[GIT PULL] perf/urgent improvements and fixes

[Arnaldo Carvalho de Melo <acme@kernel.org>]

Hi Ingo,

	Please consider pulling, this is based on 5.2-rc1+, to cope with
9c8ad7a2ff0b ("uapi, x86: Fix the syscall numbering of the mount API
syscalls [ver #2]"), as that wasn't in tip/perf/urgent at the time.

Best regards,

- Arnaldo

  tools headers UAPI: Sync kvm.h headers with the kernel sources (2019-05-27 11:05:32 -0300)

----------------------------------------------------------------
perf/urgent fixes:

BPF:

  Jiri Olsa:

  - Fixup determination of end of kernel map, to avoid having BPF programs,
    that are after the kernel headers and just before module texts mixed up in
    the kernel map.

  - Preserve eBPF maps when loading kcore.

  - Fix up DSO name padding in 'perf script --call-trace', as BPF DSO names are
    much larger than what we used to have there.

  - Add --show-bpf-events to 'perf script'.

tools UAPI header copies:

  Arnaldo Carvalho de Melo:

  - Update copy of files related to new fspick, fsmount, fsconfig, fsopen,
    move_mount and open_tree syscalls.

  - Sync cpufeatures.h, sched.h, fs.h, drm.h, i915_drm.h and kvm.h headers.

perf trace:

  Arnaldo Carvalho de Melo:

  - Add string table generators and beautify arguments for the new fspick,
    fsmount, fsconfig, fsopen, move_mount and open_tree syscalls, as well
    as new values for arguments of clone and sync_file_range syscalls.

perf version:

  Arnaldo Carvalho de Melo:

  - Append 12 git SHA chars to the version string.

Namespaces:

  Namhyung Kim:

  - Add missing byte swap ops for namespace events when processing records from
    perf.data files that could have been recorded in a arch with a different
    endianness.

  - Add missing --namespaces option to 'perf top', to generate and process
    namespace events, just like present for 'perf record'.

  - Fix access to the thread namespaces list by using the namespaces_lock.

perf data:

  Shawn Landden:

  - Fix 'strncat may truncate' build failure with recent gcc.

Intel PT:

  Andrian Hunter:

  - Fix itrace defaults for 'perf script', not using the 'use_browser' variable
    to figure out what options are better for 'script' and 'report'

  - Allow root fixing up buildid cache permissions in the perf-with-kcore.sh
    script when sharing that cache with another user.

s/390

  Thomas Richter:

  - Fix s390 missing module symbol and warning for non-root users in 'perf record'.

arm64:

  Vitaly Chikunov:

  - Fix mksyscalltbl when system kernel headers are ahead of 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.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

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/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
