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