kernel.bbclass: Complete fix for modules symlink

The fix backported in commit aa9fc551 of oe-core does not completely fix the
issue (Yocto #4595) as intended. The modules symlink is still created in the
working directory instead of in the deploy directory. To fix this, we just need
to use an absolute path to ${DEPLOYDIR} when creating the symlink.

+<title>Kernel Modification Example</title>
+
+    <para>
+        Kernel modification involves changing or adding configurations to an existing kernel,
+        changing or adding recipes to the kernel that are needed to support specific hardware features,
+        or even altering the source code itself.
+        This appendix presents simple examples that modify the kernel source code,
+        change the kernel configuration, and add a kernel source recipe.
+        <note>
+            You can use the <filename>yocto-kernel</filename> script
+            found in the <link linkend='source-directory'>Source Directory</link>
+            under <filename>scripts</filename> to manage kernel patches and configuration.

+            This example adds some simple QEMU emulator console output at boot time by
+            adding <filename>printk</filename> statements to the kernel's
+            <filename>calibrate.c</filename> source code file.
+            Booting the modified image causes the added messages to appear on the emulator's

+            <para>
+                Before you modify the kernel, you need to know what Git repositories and file
+                structures you need.
+                Briefly, you need the following:

+                        Also in this example, the Source Directory contains local copies of the

+                Once you have Source Directory set up,

+                From inside the local repository you can see the branch names and the tag names used
+                in the upstream Git repository by using either of the following commands:

+                Before we make changes to the kernel source files, this example first builds the

+                <note>
+                    Because a full build can take hours, you should check two variables in the
+                    <filename>build</filename> directory that is created after you source the
+                    <filename>&OE_INIT_FILE;</filename> script.
+                    You can find these variables

+                    in the <filename>build/conf</filename> directory in the
+                    <filename>local.conf</filename> configuration file.
+                    By default, these variables are commented out.
+                    If your host development system supports multi-core and multi-thread capabilities,
+                    you can uncomment these statements and set the variables to significantly shorten
+                    the full build time.
+                    As a guideline, set both <filename>BB_NUMBER_THREADS</filename> and
+                    <filename>PARALLEL_MAKE</filename> to twice the number
+                    of cores your machine supports.
+                </note>
+                The following two commands <filename>source</filename> the build environment setup script
+                and build the default <filename>qemux86</filename> image.
+                If necessary, the script creates the build directory:
+                <literallayout class='monospaced'>
+     $ cd ~/poky
+     $ source &OE_INIT_FILE;
+     You had no conf/local.conf file. This configuration file has therefore been

+            Whether it is managing multiple implementations of a particular feature or tuning and
+            optimizing board specific features, both flexibility and maintainability are key concerns.
+            The Linux kernels available through the Yocto Project are presented with the embedded
+            developer's needs in mind and have evolved to assist in these key concerns.
+            For example, prior methods such as applying hundreds of patches to an extracted
+            tarball have been replaced with proven techniques that allow easy inspection,
+            bisection and analysis of changes.

+        <para>
+            Kernels available through the Yocto Project, like other kernels, are based off the Linux
+            kernel releases from <ulink url='http://www.kernel.org'></ulink>.
+            At the beginning of a major development cycle, the Yocto Project team
+            chooses its kernel based on factors such as release timing, the anticipated release
+            timing of final upstream <filename>kernel.org</filename> versions, and Yocto Project
+            feature requirements.
+            Typically, the kernel chosen is in the
+            final stages of development by the community.
+            In other words, the kernel is in the release
+            candidate or "rc" phase and not yet a final release.
+            But, by being in the final stages of external development, the team knows that the
+            <filename>kernel.org</filename> final release will clearly be within the early stages of
+            the Yocto Project development window.
+        </para>
+        <para>
+            This balance allows the team to deliver the most up-to-date kernel
+            possible, while still ensuring that the team has a stable official release for
+            the baseline Linux kernel version.
+        </para>
+        <para>
+            The ultimate source for kernels available through the Yocto Project are released kernels
+            from <filename>kernel.org</filename>.
+            In addition to a foundational kernel from <filename>kernel.org</filename>, the
+            kernels available contain a mix of important new mainline
+            developments, non-mainline developments (when there is no alternative),
+            Board Support Package (BSP) developments,
+            and custom features.
+            These additions result in a commercially released Yocto Project Linux kernel that caters
+            to specific embedded designer needs for targeted hardware.
+        </para>
+        <para>
+            Once a kernel is officially released, the Yocto Project team goes into
+            their next development cycle, or upward revision (uprev) cycle, while still
+            continuing maintenance on the released kernel.
+            It is important to note that the most sustainable and stable way
+            to include feature development upstream is through a kernel uprev process.
+            Back-porting hundreds of individual fixes and minor features from various
+            kernel versions is not sustainable and can easily compromise quality.
+        </para>
+        <para>
+            During the uprev cycle, the Yocto Project team uses an ongoing analysis of
+            kernel development, BSP support, and release timing to select the best
+            possible <filename>kernel.org</filename> version.
+            The team continually monitors community kernel
+            development to look for significant features of interest.
+            The team does consider back-porting large features if they have a significant advantage.
+            User or community demand can also trigger a back-port or creation of new
+            functionality in the Yocto Project baseline kernel during the uprev cycle.
+        </para>
+        <para>
+            Generally speaking, every new kernel both adds features and introduces new bugs.
+            These consequences are the basic properties of upstream kernel development and are
+            managed by the Yocto Project team's kernel strategy.
+            It is the Yocto Project team's policy to not back-port minor features to the released kernel.
+            They only consider back-porting significant technological jumps - and, that is done
+            after a complete gap analysis.
+            The reason for this policy is that back-porting any small to medium sized change
+            from an evolving kernel can easily create mismatches, incompatibilities and very
+            subtle errors.
+        </para>
+        <para>
+            These policies result in both a stable and a cutting
+            edge kernel that mixes forward ports of existing features and significant and critical
+            new functionality.
+            Forward porting functionality in the kernels available through the Yocto Project kernel
+            can be thought of as a "micro uprev."
+            The many “micro uprevs” produce a kernel version with a mix of
+            important new mainline, non-mainline, BSP developments and feature integrations.
+            This kernel gives insight into new features and allows focused
+            amounts of testing to be done on the kernel, which prevents

+            <para>
+                As mentioned earlier, a key goal of the Yocto Project is to present the
+                developer with
+                a kernel that has a clear and continuous history that is visible to the user.
+                The architecture and mechanisms used achieve that goal in a manner similar to the

+            </para>
+            <para>
+                You can think of a Yocto Project kernel as consisting of a baseline Linux kernel with
+                added features logically structured on top of the baseline.
+                The features are tagged and organized by way of a branching strategy implemented by the
+                source code manager (SCM) Git.
+                For information on Git as applied to the Yocto Project, see the
+                "<ulink url='&YOCTO_DOCS_DEV_URL;#git'>Git</ulink>" section in the

+                The result is that the user has the ability to see the added features and
+                the commits that make up those features.
+                In addition to being able to see added features, the user can also view the history of what

+                The "Yocto Project Baseline Kernel" contains functionality that is common to every kernel

+                Placing these common features in the
+                tree this way means features don't have to be duplicated along individual branches of the

+                From the Yocto Project Baseline Kernel, branch points represent specific functionality

+                The illustration represents this through three BSP-specific branches and a real-time

+            <title>Branching Strategy and Workflow</title>
+            <para>
+                The Yocto Project team creates kernel branches at points where functionality is
+                no longer shared and thus, needs to be isolated.
+                For example, board-specific incompatibilities would require different functionality
+                and would require a branch to separate the features.
+                Likewise, for specific kernel features, the same branching strategy is used.
+            </para>
+            <para>
+                This branching strategy results in a tree that has features organized to be specific
+                for particular functionality, single kernel types, or a subset of kernel types.
+                This strategy also results in not having to store the same feature twice
+                internally in the tree.
+                Rather, the kernel team stores the unique differences required to apply the
+                feature onto the kernel type in question.
+                <note>
+                    The Yocto Project team strives to place features in the tree such that they can be
+                    shared by all boards and kernel types where possible.
+                    However, during development cycles or when large features are merged,
+                    the team cannot always follow this practice.
+                    In those cases, the team uses isolated branches to merge features.
+                </note>
+            </para>
+            <para>
+                BSP-specific code additions are handled in a similar manner to kernel-specific additions.
+                Some BSPs only make sense given certain kernel types.
+                So, for these types, the team creates branches off the end of that kernel type for all
+                of the BSPs that are supported on that kernel type.
+                From the perspective of the tools that create the BSP branch, the BSP is really no
+                different than a feature.
+                Consequently, the same branching strategy applies to BSPs as it does to features.
+                So again, rather than store the BSP twice, the team only stores the unique
+                differences for the BSP across the supported multiple kernels.
+            </para>
+            <para>
+                While this strategy can result in a tree with a significant number of branches, it is
+                important to realize that from the developer's point of view, there is a linear
+                path that travels from the baseline <filename>kernel.org</filename>, through a select
+                group of features and ends with their BSP-specific commits.
+                In other words, the divisions of the kernel are transparent and are not relevant
+                to the developer on a day-to-day basis.
+                From the developer's perspective, this path is the "master" branch.
+                The developer does not need to be aware of the existence of any other branches at all.
+                Of course, there is value in the existence of these branches
+                in the tree, should a person decide to explore them.
+                For example, a comparison between two BSPs at either the commit level or at the line-by-line
+                code <filename>diff</filename> level is now a trivial operation.
+            </para>
+            <para>
+                Working with the kernel as a structured tree follows recognized community best practices.
+                In particular, the kernel as shipped with the product, should be
+                considered an "upstream source" and viewed as a series of
+                historical and documented modifications (commits).
+                These modifications represent the development and stabilization done

+            <para>
+                Because commits only change at significant release points in the product life cycle,
+                developers can work on a branch created
+                from the last relevant commit in the shipped Yocto Project kernel.
+                As mentioned previously, the structure is transparent to the developer
+                because the kernel tree is left in this state after cloning and building the kernel.

+        <para>
+            Kernel configuration, along with kernel features, defines how a kernel
+            image is built for the Yocto Project.
+            Through configuration settings, you can customize a Yocto Project kernel to be
+            specific to particular hardware.
+            For example, you can specify sound support or networking support.
+            This section describes basic concepts behind Kernel configuration within the
+            Yocto Project and references you to other areas for specific configuration
+            applications.
+        </para>
+
+        <para>
+            Conceptually, configuration of a Yocto Project kernel occurs similarly to that needed for any
+            Linux kernel.
+            The build process for a Yocto Project kernel uses a <filename>.config</filename> file, which
+            is created through the Linux Kernel Configuration (LKC) tool.
+            You can directly set various configurations in the
+            <filename>.config</filename> file by using the <filename>menuconfig</filename>
+            tool as built by BitBake.
+            You can also define configurations in the file by using configuration fragments.
+            <note>
+                It is not recommended that you edit the <filename>.config</filename> file directly.
+            </note>
+            Here are some brief descriptions of the ways you can affect the
+            <filename>.config</filename> file:

+                <listitem><para><emphasis>The <filename>menuconfig</filename> Tool:</emphasis>
+                    One of many front-ends that allows you to define kernel configurations.
+                    Some others are <filename>make config</filename>,
+                    <filename>make nconfig</filename>, and <filename>make gconfig</filename>.
+                    In the Yocto Project environment, you must use BitBake to build the
+                    <filename>menuconfig</filename> tool before you can use it to define
+                    configurations:
+                    <literallayout class='monospaced'>
+     $ bitbake linux-yocto -c menuconfig
+                    </literallayout>
+                    After the tool is built, you can interact with it normally.
+                    You can see how <filename>menuconfig</filename> is used to change a simple

+        <title>Tree Construction</title>
+        <para>
+            This section describes construction of the Yocto Project kernel source repositories
+            as accomplished by the Yocto Project team to create kernel repositories.
+            These kernel repositories are found under the heading "Yocto Linux Kernel" at
+            <ulink url='&YOCTO_GIT_URL;/cgit.cgi'>&YOCTO_GIT_URL;/cgit.cgi</ulink>
+            and can be shipped as part of a Yocto Project release.
+            The team creates these repositories by
+            compiling and executing the set of feature descriptions for every BSP/feature
+            in the product.
+            Those feature descriptions list all necessary patches,
+            configuration, branching, tagging and feature divisions found in a kernel.
+            Thus, the Yocto Project kernel repository (or tree) is built.
+        </para>
+        <para>
+            The existence of this tree allows you to access and clone a particular
+            Yocto Project kernel repository and use it to build images based on their configurations
+            and features.
+        </para>
+        <para>
+            You can find the files used to describe all the valid features and BSPs
+            in the Yocto Project kernel in any clone of the Yocto Project kernel source repository
+            Git tree.
+            For example, the following command clones the Yocto Project baseline kernel that
+            branched off of <filename>linux.org</filename> version 3.4:
+            <literallayout class='monospaced'>
+     $ git clone git://git.yoctoproject.org/linux-yocto-3.4
+            </literallayout>
+            For another example of how to set up a local Git repository of the Yocto Project
+            kernel files, see the
+            "<ulink url='&YOCTO_DOCS_DEV_URL;#local-kernel-files'>Yocto Project Kernel</ulink>" bulleted
+            item in the Yocto Project Development Manual.
+        </para>
+        <para>
+            Once you have cloned the kernel Git repository on your local machine, you can
+            switch to the <filename>meta</filename> branch within the repository.
+            Here is an example that assumes the local Git repository for the kernel is in
+            a top-level directory named <filename>linux-yocto-3.4</filename>:
+            <literallayout class='monospaced'>
+     $ cd ~/linux-yocto-3.4
+     $ git checkout -b meta origin/meta
+            </literallayout>
+            Once you have checked out and switched to the <filename>meta</filename> branch,
+            you can see a snapshot of all the kernel configuration and feature descriptions that are
+            used to build that particular kernel repository.
+            These descriptions are in the form of <filename>.scc</filename> files.
+        </para>
+        <para>
+            You should realize, however, that browsing your local kernel repository
+            for feature descriptions and patches is not an effective way to determine what is in a
+            particular kernel branch.
+            Instead, you should use Git directly to discover the changes in a branch.
+            Using Git is an efficient and flexible way to inspect changes to the kernel.
+            For examples showing how to use Git to inspect kernel commits, see the following sections
+            in this chapter.
+            <note>
+                Ground up reconstruction of the complete kernel tree is an action only taken by the
+                Yocto Project team during an active development cycle.
+                When you create a clone of the kernel Git repository, you are simply making it
+                efficiently available for building and development.

+        <para>
+            The following steps describe what happens when the Yocto Project Team constructs
+            the Yocto Project kernel source Git repository (or tree) found at
+            <ulink url='&YOCTO_GIT_URL;/cgit.cgi'></ulink> given the
+            introduction of a new top-level kernel feature or BSP.
+            These are the actions that effectively create the tree
+            that includes the new feature, patch or BSP:

+            Once a local Git repository of the Yocto Project kernel exists on a development system,
+            you can consider the compilation phase of kernel development - building a kernel image.
+            Some prerequisites exist that are validated by the build process before compilation
+            starts:

+            The OpenEmbedded build system makes sure these conditions exist before attempting compilation.

+        <para>
+            Before building a kernel, the build process verifies the tree
+            and configures the kernel by processing all of the
+            configuration "fragments" specified by feature descriptions in the <filename>.scc</filename>
+            files.
+            As the features are compiled, associated kernel configuration fragments are noted
+            and recorded in the <filename>meta-*</filename> series of directories in their compilation order.
+            The fragments are migrated, pre-processed and passed to the Linux Kernel
+            Configuration subsystem (<filename>lkc</filename>) as raw input in the form
+            of a <filename>.config</filename> file.
+            The <filename>lkc</filename> uses its own internal dependency constraints to do the final
+            processing of that information and generates the final <filename>.config</filename> file
+            that is used during compilation.

+
+        <para>
+            Using the board's architecture and other relevant values from the board's template,

+
+        <para>
+            The other thing that you notice once you configure a kernel is that
+            the build process generates a build tree that is separate from your kernel's local Git
+            source repository tree.
+            This build tree has a name that uses the following form, where
+            <filename>${MACHINE}</filename> is the metadata name of the machine (BSP) and "kernel_type" is one
+            of the Yocto Project supported kernel types (e.g. "standard"):
+        <literallayout class='monospaced'>
+     linux-${MACHINE}-&lt;kernel_type&gt;-build
+        </literallayout>
+        </para>
+
+        <para>
+            The existing support in the <filename>kernel.org</filename> tree achieves this
+            default functionality.
+        </para>
+
+        <para>
+            This behavior means that all the generated files for a particular machine or BSP are now in
+            the build tree directory.
+            The files include the final <filename>.config</filename> file, all the <filename>.o</filename>
+            files, the <filename>.a</filename> files, and so forth.
+            Since each machine or BSP has its own separate build directory in its own separate branch
+            of the Git repository, you can easily switch between different builds.

+

+            As previously noted, the Yocto Project kernel has built-in Git integration.
+            However, these utilities are not the only way to work with the kernel repository.
+            The Yocto Project has not made changes to Git or to other tools that
+            would invalidate alternate workflows.
+            Additionally, the way the kernel repository is constructed results in using
+            only core Git functionality, thus allowing any number of tools or front ends to use the
+            resulting tree.

+
+        <para>
+            This section contains several workflow examples.

+            You can find Git documentation at
+            <ulink url='http://git-scm.com/documentation'></ulink>.
+            You can find a simple overview of using Git with the Yocto Project in the

+
+            <para>
+                A common question when working with a kernel is:
+                "What changes have been applied to this tree?"
+            </para>
+
+            <para>
+                In projects that have a collection of directories that
+                contain patches to the kernel, it is possible to inspect or "grep" the contents
+                of the directories to get a general feel for the changes.
+                This sort of patch inspection is not an efficient way to determine what has been
+                done to the kernel.
+                The reason it is inefficient is because there are many optional patches that are
+                selected based on the kernel type and the feature description.
+                Additionally, patches could exist in directories that are not included in the search.
+            </para>
+
+            <para>
+                A more efficient way to determine what has changed in the branch is to use
+                Git and inspect or search the kernel tree.
+                This method gives you a full view of not only the source code modifications,
+                but also provides the reasons for the changes.

+                    Following are a few examples that show how to use Git commands to examine changes.
+                    Because Git repositories in the Yocto Project do not break existing Git
+                    functionality, and because there exists many permutations of these types of
+                    Git commands, many methods exist by which you can discover changes.
+                    <note>
+                        In the following examples, unless you provide a commit range,
+                        <filename>kernel.org</filename> history is blended with Yocto Project
+                        kernel changes.
+                        You can form ranges by using branch names from the kernel tree as the
+                        upper and lower commit markers with the Git commands.
+                        You can see the branch names through the web interface to the
+                        Yocto Project source repositories at
+                        <ulink url='http://git.yoctoproject.org/cgit.cgi'></ulink>.
+                        For example, the branch names for the <filename>linux-yocto-3.4</filename>

+                    To see a full range of the changes, use the

+
+                <para>
+                    Here is an example that looks at what has changed in the

+
+                <para>
+                    If you want to see code differences associated with all the changes, use

+                    Developers use tags in the Yocto Project kernel tree to divide changes for significant

+                    Once you know a particular tag, you can use Git commands

+                    to show the branches that contain a particular feature.
+                    This command shows the branches that contain the <filename>systemtap</filename>

+                    This section describes how you can "bulk" export changes that have not
+                    been separated or divided.
+                    This situation works well when you are simply storing patches outside of the kernel
+                    source repository, either permanently or temporarily, and you are not committing
+                    incremental changes during development.

+                        This technique is not appropriate for full integration of upstream submission
+                        because changes are not properly divided and do not provide an avenue for per-change
+                        commit messages.
+                        Therefore, this example assumes that changes have not been committed incrementally

+                        The reason for this recommendation is because the branch or tag provides a
+                        reference point to facilitate locating and exporting local changes.

+
+                <para>
+                    This section describes how to export changes for external upstream submission.
+                    If the patch series is large or the maintainer prefers to pull
+                    changes, you can submit these changes by using a pull request.
+                    However, it is common to send patches as an email series.
+                    This method allows easy review and integration of the changes.
+                    <note>
+                        Before sending patches for review be sure you understand the
+                        community standards for submitting and documenting changes and follow their best practices.
+                        For example, kernel patches should follow standards such as:
+                        <itemizedlist>
+                            <listitem><para>
+                                <ulink url='http://linux.yyz.us/patch-format.html'></ulink></para></listitem>
+                            <listitem><para>Documentation/SubmittingPatches (in any linux
+                                kernel source tree)</para></listitem>
+                        </itemizedlist>
+                    </note>
+                </para>
+
+                <para>
+                    The messages used to commit changes are a large part of these standards.
+                    Consequently, be sure that the headers for each commit have the required information.
+                    For information on how to follow the Yocto Project commit message standards, see the
+                    "<ulink url='&YOCTO_DOCS_DEV_URL;#how-to-submit-a-change'>How to Submit a
+                    Change</ulink>" section in the Yocto Project Development Manual.
+                </para>
+
+                <para>
+                    If the initial commits were not properly documented or do not meet those standards,
+                    you can re-base by using the <filename>git rebase -i</filename> command to
+                    manipulate the commits and
+                    get them into the required format.
+                    Other techniques such as branching and cherry-picking commits are also viable options.
+                </para>
+
+                <para>
+                    Once you complete the commits, you can generate the email that sends the patches
+                    to the maintainer(s) or lists that review and integrate changes.
+                    The command <filename>git send-email</filename> is commonly used to ensure
+                    that patches are properly
+                    formatted for easy application and avoid mailer-induced patch damage.
+                </para>

+                <para>
+                    The following is an example of dumping patches for external submission:

+                    When you want to export changes for import into another
+                    Source Code Manager (SCM), you can use any of the previously discussed
+                    techniques.
+                    However, if the patches are manually applied to a secondary tree and then
+                    that tree is checked into the SCM, you can lose change information such as
+                    commit logs.
+                    This process is not recommended.
+                </para>
+
+                <para>
+                    Many SCMs can directly import Git commits, or can translate Git patches so that
+                    information is not lost.
+                    Those facilities are SCM-dependent and you should use them whenever possible.

+                This section describes kernel development in an SCM other than Git,
+                which is not the same as exporting changes to another SCM described earlier.
+                For this scenario, you use the OpenEmbedded build system to

+                    This method is preferred because it has the most flexibility and potential to maintain

+
+   Structure
+   ---------
+
+   The stylesheet is divided into the following sections:
+
+       Positioning
+          Margins, paddings, width, font-size, clearing.
+       Decorations
+          Borders, style
+       Colors
+          Colors
+       Graphics
+          Graphical backgrounds
+       Nasty IE tweaks
+          Workarounds needed to make it work in internet explorer,
+          currently makes the stylesheet non validating, but up until
+          this point it is validating.
