Merge tag 'perf-core-for-mingo-2' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent
Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:
User visible changes:
- The mmap address range for the ring buffer now is calculated using the
contents of /proc/sys/kernel/perf_event_mlock_kb.
This fixes an -EPERM case where 'trace' was trying to use more than what
is configured on perf_event_mlock_kb. (Arnaldo Carvalho de Melo)
Infrastructure changes:
- Move bitops definitions so that they match the header file hierarchy
in the kernel sources where that code came from. (Arnaldo Carvalho de Melo)
- Adopt round{down,up}_pow_of_two from the kernel and use it instead of
equivalent code, so that we reuse more kernel code and make tools/ look
more like kernel source code, to encourage further contributions from
kernel hackers (Arnaldo Carvalho de Melo)
- Fix use after free in filename__read_build_id (Mitchell Krome)
