  tools headers UAPI: Synch KVM's svm.h header with the kernel (2022-06-26 12:32:55 -0300)

----------------------------------------------------------------
perf tools fixes for v5.19: 2nd batch

- Enable ignore_missing_thread in 'perf stat', enabling counting with '--pid'
  when threads disappear during counting session setup.

- Adjust output data offset for backward compatibility in 'perf inject'.

- Fix missing free in copy_kcore_dir() in 'perf inject'.

- Fix caching files with a wrong build ID.

- Sync drm, cpufeatures, vhost and svn headers with the kernel.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
Gwith a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one.

There is still the mageia:7 distro + clang 8 failure, seemingly unrelated to
the patches in this series, it'll be investigated. It builds just fine with gcc
8.4.

There is also a strange one with openmandriva:4.2 and openmandriva:cooker,
where on the feature build test it doesn't manage to find libpthread, because
the pthread functions (and the ones in librt, IIRC) are on the main libc, so a
test for that is needed to avoid adding '-lpthread and -lrt' in distros where
this is the case. It's in the TODO list.

Ubuntu 20.04 is failing on a corner case where perf links with libllvm and libclang,
which isn't the default perf build.

Cross building on 32-bit MIPS debian is failing due to redefinition of 'struct flock'
on a 'perf trace' beautifier, to be investigated.

Another regression alt:sisyphus, will be eventually on the non-default libllvm build.
