+Subject: [PATCH 1/2] fix: cpu/hotplug: Remove deprecated CPU-hotplug
+ functions. (v5.15)
+
+The CPU-hotplug functions get|put_online_cpus() were deprecated in v4.13
+and removed in v5.15.
+
+See upstream commits :
+
+commit 8c854303ce0e38e5bbedd725ff39da7e235865d8
+Author: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
+Date: Tue Aug 3 16:16:21 2021 +0200
+
+ cpu/hotplug: Remove deprecated CPU-hotplug functions.
+
+ No users in tree use the deprecated CPU-hotplug functions anymore.
+
+ Remove them.
+
+Introduced in v4.13 :
+
+ commit 8f553c498e1772cccb39a114da4a498d22992758
+ Author: Thomas Gleixner <tglx@linutronix.de>
+ Date: Wed May 24 10:15:12 2017 +0200
+
+ cpu/hotplug: Provide cpus_read|write_[un]lock()
+
+ The counting 'rwsem' hackery of get|put_online_cpus() is going to be
+ replaced by percpu rwsem.
+
+ Rename the functions to make it clear that it's locking and not some
+ refcount style interface. These new functions will be used for the
+ preparatory patches which make the code ready for the percpu rwsem
+ conversion.
+
+ Rename all instances in the cpu hotplug code while at it.
+
+Upstream-Status: backport [https://git.lttng.org/?p=lttng-modules.git;a=commit;h=ffcc873470121ef1ebb110df3d9038a38d9cb7cb]

+Subject: [PATCH 2/2] fix: Revert "Makefile: Enable -Wimplicit-fallthrough for
+ Clang" (v5.15)
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Starting with v5.15, "-Wimplicit-fallthrough=5" was added to the build
+flags which requires the use of "__attribute__((__fallthrough__))" to
+annotate fallthrough case statements.
+
+See upstream commit by the man himself:
+
+ commit d936eb23874433caa3e3d841cfa16f5434b85dcf
+ Author: Linus Torvalds <torvalds@linux-foundation.org>
+ Date: Thu Jul 15 18:05:31 2021 -0700
+
+ Revert "Makefile: Enable -Wimplicit-fallthrough for Clang"
+
+ This reverts commit b7eb335e26a9c7f258c96b3962c283c379d3ede0.
+
+ It turns out that the problem with the clang -Wimplicit-fallthrough
+ warning is not about the kernel source code, but about clang itself, and
+ that the warning is unusable until clang fixes its broken ways.
+
+ In particular, when you enable this warning for clang, you not only get
+ warnings about implicit fallthroughs. You also get this:
+
+ warning: fallthrough annotation in unreachable code [-Wimplicit-fallthrough]
+
+ which is completely broken becasue it
+
+ (a) doesn't even tell you where the problem is (seriously: no line
+ numbers, no filename, no nothing).
+
+ (b) is fundamentally broken anyway, because there are perfectly valid
+ reasons to have a fallthrough statement even if it turns out that
+ it can perhaps not be reached.
+
+ In the kernel, an example of that second case is code in the scheduler:
+
+ switch (state) {
+ case cpuset:
+ if (IS_ENABLED(CONFIG_CPUSETS)) {
+ cpuset_cpus_allowed_fallback(p);
+ state = possible;
+ break;
+ }
+ fallthrough;
+ case possible:
+
+ where if CONFIG_CPUSETS is enabled you actually never hit the
+ fallthrough case at all. But that in no way makes the fallthrough
+ wrong.
+
+ So the warning is completely broken, and enabling it for clang is a very
+ bad idea.
+
+ In the meantime, we can keep the gcc option enabled, and make the gcc
+ build use
+
+ -Wimplicit-fallthrough=5
+
+ which means that we will at least continue to require a proper
+ fallthrough statement, and that gcc won't silently accept the magic
+ comment versions. Because gcc does this all correctly, and while the odd
+ "=5" part is kind of obscure, it's documented in [1]:
+
+ "-Wimplicit-fallthrough=5 doesn’t recognize any comments as
+ fallthrough comments, only attributes disable the warning"
+
+ so if clang ever fixes its bad behavior we can try enabling it there again.
