When the architecture and debug specific build and runtime dependencies
were introduced, they were only applicable to "newer" kernel versions
and were enabled in the version specific recipes.
These are now common dependencies, so we can avoid the duplication and
move them to a common location.
We also change the adhoc nature of the existing elfutils definition,
as it is now detected by the kernel build and we no longer need the
work around to the native sysroot.
Finally, we change the undocumented KERNEL_DEBUG_OPTIONS to KERNEL_DEBUG
and use it to conditionally enable features that need extended support
(and support sometimes out of oe-core).

The kernel Makfile uses pkgconfig to check for libelf when enabling

the kernel Makefiles hardcode 'pkgconfig', so fail to pick up our
pkgconfig-native binary that would report the correct flags and paths
for libelf support.
Rather than patching the kernel Makefile's to use pkgconfig-native,
we can use the KERNEL_EXTRA_ARGS variable to pass the definition of
HOST_LIBELF_LIBS via the kernel build commmand line.
We conditionally set HOST_LIBELF_LIBS based on "stack" being in
a newly introduced variable KERNEL_DEBUG_OPTIONS. The value of
HOST_LIBELF_LIBS is the same as pkgconfig-native would set in a
kernel build (but we cannot call pkgconfig at the point this
variable is set).

Some distros may want to provide alternate kernel "flavors" via feeds or
within bootable images. For example, readily available builds which
provide certain diagnostic features can enable developers and testers to
more quickly resolve issues by avoiding lengthy kernel builds.
This change allows for building multiple flavors of the kernel and
module packages by templatizing kernel package names via a new
KERNEL_PACKAGE_NAME variable in kernel.bbclass. It defaults to the old
name of "kernel", but can be overridden by certain recipes providing
alternate kernel flavors.
To maintain compatibility, recipes providing alternate kernel flavors
cannot be the "preferred provider" for virtual/kernel. This is because
OE puts the preferred provider's build and source at
"tmp-glibc/work-shared/$MACHINE/kernel-build-artifacts/" and
"tmp-glibc/work-shared/$MACHINE/kernel-source/" instead of
"tmp-glibc/work/*/$PN/" like other recipes. Therefore, recipes using the
default KERNEL_PACKAGE_NAME="kernel" follows the old semantics -- build
in the old location and may be preferred provider -- while recipes using
all other KERNEL_PACKAGE_NAME's build from the normal WORKDIR and don't
provide "virtual/kernel".
Testing:
1. Add `KERNEL_PACKAGE_NAME_pn-linux-yocto-tiny = "tiny-linux"`
to local.conf so that linux-yocto-tiny may build alongside
the main kernel (linux-yocto).
2. `bitbake linux-yocto linux-yocto-tiny` to build both kernel flavors.
3. Verified image and modules IPKs exist for both:
tmp-glibc/deploy/ipk/qemux86/kernel-* for linux-yocto
tmp-glibc/deploy/ipk/qemux86/tiny-linux* for linux-yocto-tiny
4. Verified linux-yocto is the "preferred provider", and was built in
shared directory: tmp-glibc/work-shared/qemux86/kernel-*
5. Add `CORE_IMAGE_BASE_INSTALL_append_pn-core-image-base = "tiny-linux"`
to local.conf to install both kernel flavors in core-image-base.
6. `bitbake core-image-base` to build an image.
7. Verified image contains two bzImage's under /boot/, with
"yocto-standard" (linux-yocto recipe) selected to boot via symlink.

When working on the yocto-bsp and kernel-lab update for yocto 1.2
we found it was impossible for a end-user BSP to isolate patches
on a branch, since with the following commit:
[kernel-yocto: enforce SRC_URI specified branch]
Any new branch would be switched to whatever was specified on the
SRC_URI and undoing the work that the yocto-bsp tool did to support
board specific patches.
To fix this, we'll keep the enforcing of branch consistency enabled
by default, but introduce a variable "KMETA_AUDIT" that when not
set will skip the check.
There's no impact for existing users, and it is only something that
other plumbing commands and tools will need to use (or care about).

After a linux-yocto style kernel is configured, a kernel configuration
audit is executed to detect common errors or issues with the config.
This output used to be visible, but was made less obvious to not alarm
users unnecessarily (since some configuration issues are acceptable).
There are some classes of configuration issue that are worth being
visible, and that is specified configuration values that do not make the
final .config. These dropped options can result in any number of runtime
failures, so flagging them at build time makes sense.
The visibility of auditing is controlled by KCONF_AUDIT_LEVEL:
0: no reporting
1: report options that are specified, but not in the final config
2: report options that are not hardware related, but set by a BSP
The default level is 1, with level 2 and above being for BSP development
only.
If these conditions are detected, warnings will be generated as follows:
WARNING: [kernel config]: specified values did not make it into the
kernel's final configuration:
Value requested for CONFIG_SND_PCSP not in final ".config"
Requested value: "CONFIG_SND_PCSP=y"

CONFIG_EFIVAR_FS
CONFIG_EFI_PARTITION

CONFIG_NETDEVICES
CONFIG_PARTITION_ADVANCED
CONFIG_WEXT_CORE
CONFIG_WEXT_PROC

At this point thse are only a warnings, since there needs to be time for

something like this when building for MACHINE=sys940x (using intel-common):
tmp/work/core2-32-intel-common-poky-linux/linux-yocto-dev/ \
3.13++gitAUTOINC+e5d23e7879_889c6bec6b-r0/linux-sys940x-noemgd-standard-build
Note the descrepancy between core2-32-intel-common and
linux-sys940x-noemgd-standard-build. This becomes counterintuitive at
the very least when switching to another machine and attempting to reuse
this build. This patch swaps MACHINE for PACKAGE_ARCH (which is
typically MACHINE_ARCH for linux-yocto), resulting in the following
build path:
tmp/work/core2-32-intel-common-poky-linux/linux-yocto-dev/ \
3.13++gitAUTOINC+e5d23e7879_889c6bec6b-r0/linux-core2-32-intel-common-standard-build
The impact to existing MACHINEs is a replace of - with _ if MACHINE
contains one or more - charachters.

As reported by Martin Jansa <martin.jansa@gmail.com>, the following error happens
when building in a minimal environment:
| BC kernel/timeconst.h
| /bin/sh: bc: command not found
| make[3]: *** [kernel/timeconst.h] Error 127
| make[2]: *** [kernel] Error 2
| make[2]: *** Waiting for unfinished jobs....
kernel commit 70730bca [kernel: Replace timeconst.pl with a bc script] added
a kernel dependency on bc. To support the build of linux-yocto recipes in
these configurations, we add bc-native to the common dependencies.

[YOCTO #1614]
Add the kernel headers to the kernel-dev package. This packages what was
already built and kept in sysroots for building modules with bitbake.
Making this available on the target requires removing some additional
host binaries.
Move the location to /usr/src/kernel
Before use on the target, the user will need to:
# cd /usr/src/kernel
# make scripts
This renders the kernel-misc recipe empty, so remove it.
As we use /usr/src/kernel in several places (and I missed one in the
previous version), add a KERNEL_SRC_DIR variable and use that throughout
the class to avoid update errors in the future.
Now that we package the kernel headers, drop the
kernel_package_preprocess function which removed them from PKGD.
All *-sdk image recipes include dev-pkgs, so the kernel-dev package will
be installed by default on all such images.

When making changes to kernel.bbclass, it would be nice not to have to
manually change the PR of every linux-yocto*.bb file that requires it.
Move the "require kernel" line to linux-yocto.inc and update the
linux-yocto recipes to use INC_PR.
