Merge tag 'perf-core-for-mingo-5.5-20191128' 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:
perf script:
Adrian Hunter:
- Fix brstackinsn for AUXTRACE.
- Fix invalid LBR/binary mismatch error.
perf diff:
Arnaldo Carvalho de Melo:
- Use llabs() with 64-bit values, fixing the build in some 32-bit
architectures.
perf pmu:
Andi Kleen:
- Use file system cache to optimize sysfs access.
x86:
Adrian Hunter:
- Add some more Intel instructions to the opcode map and to the perf
test entry:

perf affinity:
Andi Kleen:
- Add infrastructure to save/restore affinity
perf maps:
Arnaldo Carvalho de Melo:
- Merge 'struct maps' with 'struct map_groups', as there is a
1x1 relationship, simplifying code overal.
perf build:
Jiri Olsa:
- Allow to link with libbpf dynamicaly.
