* Perf: ARM: Support 32bit armv8-pmuv3 driverPatrick Fay2017-05-25
| | | | | | | | | | | Currently perf_event.c is 64bit specific due to inline assembly. Driver needs to support 32bit as well. Move the assembly code to asm/perf_event.h so that perf_event.c is 32/64 bit agnostic and move perf_event.c to drivers/perf from 64bit-specific arch dir.

* arm: perf: factor arm_pmu core out to driversMark Rutland2015-07-31
To enable sharing of the arm_pmu code with arm64, this patch factors it out to drivers/perf/. A new drivers/perf directory is added for performance monitor drivers to live under. MAINTAINERS is updated accordingly. Files added previously without a corresponsing MAINTAINERS update (perf_regs.c, perf_callchain.c, and perf_event.h) are also added.
