Note: Upgrade lttng-modules to 2.13.14 to fix fcheck error which occurs
with commit 782202de6478f68caaed4567017095ad906c4eef in kernel "file: Rename fcheck
lookup_fd_rcu" which does replaces fcheck with lookup_fd_rcu.

The root cause appears to be that this particular mips kernel does not
have CONFIG_COMPACTION avaiable, and hence we end up with the struct
declaration within this tracepoint, and then conflicting types.

While putting the conditional around only compaction_migratepages seemed
sufficient to get the build working, it doesn't look like any of the
tracepoints should be valid, so we extend it to all definitions.

  random: remove unused tracepoints

  These explicit tracepoints aren't really used and show sign of aging.
  It's work to keep these up to date, and before I attempted to keep them
  up to date, they weren't up to date, which indicates that they're not
  really used. These days there are better ways of introspecting anyway.

Which causes the following build failure
lttng-modules-2.13.3/src/probes/lttng-probe-random.c:18:10: fatal error: trace/events/random.h: No such file or directory
|    18 | #include <trace/events/random.h>

7cdf493ae7 lttng-modules: fix build against 5.18-rc7+
lttng-modules fails to build against 5.18-rc7, the details of the fix
are as follows:

   The commit [fix: sched/tracing: Don't re-read p->state when emitting
   sched_switch event (v5.18)] was correct, but the kernel changed their
   mind with the following commit:

      commit 9c2136be0878c88c53dea26943ce40bb03ad8d8d
      Author: Delyan Kratunov <delyank@fb.com>
      Date:   Wed May 11 18:28:36 2022 +0000

          sched/tracing: Append prev_state to tp args instead

          Commit fa2c3254d7cf (sched/tracing: Don't re-read p->state when emitting
          sched_switch event, 2022-01-20) added a new prev_state argument to the
          sched_switch tracepoint, before the prev task_struct pointer.

          This reordering of arguments broke BPF programs that use the raw
          tracepoint (e.g. tp_btf programs). The type of the second argument has
          changed and existing programs that assume a task_struct* argument
          (e.g. for bpf_task_storage access) will now fail to verify.

          If we instead append the new argument to the end, all existing programs
          would continue to work and can conditionally extract the prev_state
          argument on supported kernel versions.

          Fixes: fa2c3254d7cf (sched/tracing: Don't re-read p->state when emitting sched_switch event, 2022-01-20)

   By reordering the parameters (again) we can get back up and building.

b3ea0a07d4 lttng-modules: support kernel 5.18+
Backporting changes from lttng master to support building against
the 5.18+ kernel. No changes required to the patches. Once a new
-stable 2.13.x is released, we can drop these patches. To enable
newer kernel development against the LTS, it is worth pulling these
in while we wait for an upstream release.

85a97d3985 lttng-modules: Make it build when CONFIG_TRACEPOINTS is not enabled again
Makefile-Do-not-fail-if-CONFIG_TRACEPOINTS-is-not-en.patch was updated
with the 2.13.0 update (commit 5dad15af), but unfortunately it no
longer did what it was intended to do. There is also
0001-src-Kbuild-change-missing-CONFIG_TRACEPOINTS-to-warn.patch, which
was based on the former patch, but it too does not solve the problem.

Unify the two patches, and actually disable building of the kernel
module if CONFIG_TRACEPOINTS is not enabled, the way it was intended.

	* Fix: version check error in btrfs instrumentation
	* Fix: update btrfs instrumentation for kernel 4.14
	* Fix: update writeback instrumentation for kernel 4.14
	* Fix: update block instrumentation for kernel 4.14
	* Fix: vmalloc wrapper on kernel < 2.6.38
	* Fix: vmalloc wrapper on kernel >= 4.12
	* Add kmalloc failover to vmalloc
	* Fix: mmap: caches aliased on virtual addresses

into a similar problem as Linux experienced with __builtin_constant_p

f5b4ca2ad7 lttng-modules: Do not fail if CONFIG_TRACEPOINTS is not enabled
The lttng-modules are being pulled by the tools-profile image feature,
however, not every kernel has the CONFIG_TRACEPOINTS feature enabled.

This change makes the build do not fail when CONFIG_TRACEPOINTS is not
available, allowing it to be kept being pulled by default.
