Since commit e2bcbd7769ee ("tools headers UAPI: remove stale lirc.h"),
the build of the selftests fails on rhel 8 since its version of
/usr/include/linux/lirc.h has no definition of RC_PROTO_RCMM32, etc [1].

These are some trivial fixups, which were needed to build the tests with
clang and -Werror. The following issues are fixed:
- Remove various unused variables.
- In child_poll_leader_exit_test, clang isn't smart enough to realize
syscall(SYS_exit, 0) won't return, so it complains we never return
from a non-void function. Add an extra exit(0) to appease it.
- In test_pidfd_poll_leader_exit, ret may be branched on despite being
uninitialized, if we have !use_waitpid. Initialize it to zero to get
the right behavior in that case.

When running the pidfd_fdinfo_test on arm64, it fails for me. After some
digging, the reason is that the child exits due to SIGBUS, because it
overflows the 1024 byte stack we've reserved for it.
To fix the issue, increase the stack size to 8192 bytes (this number is
somewhat arbitrary, and was arrived at through experimentation -- I kept
doubling until the failure no longer occurred).
Also, let's make the issue easier to debug. wait_for_pid() returns an
ambiguous value: it may return -1 in all of these cases:
1. waitpid() itself returned -1
2. waitpid() returned success, but we found !WIFEXITED(status).
3. The child process exited, but it did so with a -1 exit code.
There's no way for the caller to tell the difference. So, at least log
which occurred, so the test runner can debug things.
While debugging this, I found that we had !WIFEXITED(), because the
child exited due to a signal. This seems like a reasonably common case,
so also print out whether or not we have WIFSIGNALED(), and the
associated WTERMSIG() (if any). This lets us see the SIGBUS I'm fixing
clearly when it occurs.
Finally, I'm suspicious of allocating the child's stack on our stack.
man clone(2) suggests that the correct way to do this is with mmap(),
and in particular by setting MAP_STACK. So, switch to doing it that way
instead.

Paul Heidekrüger pointed out that the Linux Kernel Memory Model
documentation doesn't mention the distinction between syntactic and
semantic dependencies. This is an important difference, because the
compiler can easily break dependencies that are only syntactic, not
semantic.
This patch adds a few paragraphs to the LKMM documentation explaining
these issues and illustrating how they can matter.

The torture-test scripting's long-standing use of KVM as the environment
variable tracking the pathname of the rcutorture directory now conflicts
with allmodconfig builds due to the virt/kvm/Makefile.kvm file's use
of this as a makefile variable. This commit therefore changes the
torture-test scripting from KVM to RCUTORTURE, avoiding the name conflict.

but not TREE01.2.

Compressing KASAN vmlinux files reduces torture.sh res file size from
about 100G to about 50G, which is good, but the KCSAN vmlinux files

In a clear-cut case of "not thinking big enough", kvm.sh limits the
multipliers for torture-test scenarios to three digits. Although this is
large enough for any single system that I have ever run rcutorture on,
it does become a problem when you want to use kvm-remote.sh to run as
many instances of TREE09 as fit on a set of 20 systems with 80 CPUs each.
Yes, one could simply say "--configs '800*TREE09 800*TREE09'", but this
commit removes the need for that sort of hacky workaround by permitting
four-digit repetition numbers, thus allowing "--configs '1600*TREE09'".
Five-digit repetition numbers remain off the menu. Should they ever
really be needed, they can easily be added!

When cross-building tools with clang, we run `which $(CROSS_COMPILE)gcc`
to detect whether a GCC toolchain provides the standard libraries. It is
only a helper because some distros put libraries where LLVM does not
automatically find them. On other systems, LLVM detects the libc
automatically and does not need this. There, it is completely fine not
to have a GCC at all, but some versions of `which' display an error when
the command is not found:
which: no aarch64-linux-gnu-gcc in ($PATH)
Since the error can safely be ignored, throw it to /dev/null.

To pick the changes in:

This actually adds a new prctl arg, but it has to be dealt with

This new PR_SET_VMA value isn't in sequence with all the other prctl
arguments and instead uses a big, 0x prefixed hex number: 0x53564d41 (S V M A).
This makes it harder to generate a string table as it would be rather
sparse, so make the regexp more stricter to avoid catching those.
A followup patch for 'perf trace' to cope with such oddities will be
needed, but then its a matter for the next merge window.
The next patch will update the prctl.h file to cope with this perf build

vdso_test_abi contains a batch of tests that verify the validity of the
vDSO ABI.
When a vDSO symbol is not found the relevant test is skipped reporting
KSFT_SKIP. All the tests return values are then added in a single
variable which is checked to verify failures. This approach can have
side effects which result in reporting the wrong kselftest exit status.
Fix vdso_test_abi verifying the return code of each test separately.

Currently we unconditionally test the ability to set the vector length
inheritance flag via ptrace meaning that we generate false failures on
systems that don't support SVE when we attempt to set the vector length
there. Check the hwcap and mark the tests as skipped when it's not present.
