linux.git/tools/include, branch v4.18.19

Merge branch 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

2018-08-05T16:13:07+00:00

Pull perf fixes from Thomas Gleixner:
 "A set of fixes for perf:

  Kernel side:

   - Fix the hardcoded index of extra PCI devices on Broadwell which
     caused a resource conflict and triggered warnings on CPU hotplug.

  Tooling:

   - Update the tools copy of several files, including perf_event.h,
     powerpc's asm/unistd.h (new io_pgetevents syscall), bpf.h and x86's
     memcpy_64.s (used in 'perf bench mem'), silencing the respective
     warnings during the perf tools build.

   - Fix the build on the alpine:edge distro"

  perf/x86/intel/uncore: Fix hardcoded index of Broadwell extra PCI devices
  perf tools: Fix the build on the alpine:edge distro

  tools headers uapi: Update tools's copy of linux/perf_event.h

tools headers uapi: Refresh linux/bpf.h copy

2018-07-30T15:35:45+00:00

To get the changes in:

  4c79579b44b1 ("bpf: Change bpf_fib_lookup to return lookup status")

That do not entail changes in tools/perf/ use of it, elliminating the
following perf build warning:

  Warning: Kernel ABI header at 'tools/include/uapi/linux/bpf.h' differs from latest version at 'include/uapi/linux/bpf.h'

tools headers uapi: Update tools's copy of linux/perf_event.h

2018-07-30T14:41:56+00:00

To get the changes in:

  6cbc304f2f36 ("perf/x86/intel: Fix unwind errors from PEBS entries (mk-II)")

That do not imply any changes in the tooling side, the (ab)use of
sample_type is entirely done in kernel space, nothing for userspace to
witness here.

This cures the following warning during perf's build:

  Warning: Kernel ABI header at 'tools/include/uapi/linux/perf_event.h' differs from latest version at 'include/uapi/linux/perf_event.h'

tools headers uapi: Synchronize drm/drm.h

To pick up the new ioctls added in these csets:

The DRM caps are not yet being decoded in 'perf trace', so this sync
doesn't incur in any change in behaviour in any tools, just silencing
this tools/perf/ build warning:
