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.

+Subject: [PATCH 02/10] Fix: tracepoint event: allow same provider and event
+ name
+
+Using the same name for the provider (TRACE_SYSTEM) and event name
+causes a compilation error because the same identifiers are emitted
+twice.
+
+Fix this by prefixing the provider identifier with
+"__provider_event_desc___".

+ emitting sched_switch event (v5.18)
+
+See upstream commit :
+
+  commit fa2c3254d7cfff5f7a916ab928a562d1165f17bb
+  Author: Valentin Schneider <valentin.schneider@arm.com>

+
+    sched/tracing: Don't re-read p->state when emitting sched_switch event
+
+    As of commit
+
+      c6e7bd7afaeb ("sched/core: Optimize ttwu() spinning on p->on_cpu")
+
+    the following sequence becomes possible:
+
+                          p->__state = TASK_INTERRUPTIBLE;
+                          __schedule()
+                            deactivate_task(p);
+      ttwu()
+        READ !p->on_rq
+        p->__state=TASK_WAKING
+                            trace_sched_switch()
+                              __trace_sched_switch_state()
+                                task_state_index()
+                                  return 0;
+
+    TASK_WAKING isn't in TASK_REPORT, so the task appears as TASK_RUNNING in
+    the trace event.
+
+    Prevent this by pushing the value read from __schedule() down the trace
+    event.

+
+See upstream commit :
+
+  commit 14c174633f349cb41ea90c2c0aaddac157012f74
+  Author: Jason A. Donenfeld <Jason@zx2c4.com>
+  Date:   Thu Feb 10 16:40:44 2022 +0100
+
+    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.

+ (v5.18)
+
+See upstream commit :
+
+  commit 73f9b911faa74ac5107879de05c9489c419f41bb
+  Author: Masami Hiramatsu <mhiramat@kernel.org>
+  Date:   Sat Mar 26 11:27:05 2022 +0900
+
+    kprobes: Use rethook for kretprobe if possible
+
+    Use rethook for kretprobe function return hooking if the arch sets
+    CONFIG_HAVE_RETHOOK=y. In this case, CONFIG_KRETPROBE_ON_RETHOOK is
+    set to 'y' automatically, and the kretprobe internal data fields
+    switches to use rethook. If not, it continues to use kretprobe
+    specific function return hooks.

+    mm: compaction: cleanup the compaction trace events
+
+    As Steven suggested [1], we should access the pointers from the trace
+    event to avoid dereferencing them to the tracepoint function when the
+    tracepoint is disabled.
