[PATCH v6 0/7] arm64: perf: Broadcom Vulcan PMU support

[Ashok Kumar]

Cleaned up event naming convention as per ARM ARM.

Added macros for complete ARMv8 recommended implementation defined events.

changed pmu register access to make use of read/write_sys_reg.

Common architectural and micro-architectural events which are exported to /sys
are now filtered using PMCEIDn_EL0

Added support for Broadcom Vulcan PMU.

changes since v5 [5]:
 Incorporated the following review comments from Mark.
 * Folded armv8pmu_probe_num_events and armv8pmu_read_common_events_bitmap.
 * Changed format string in event number print from 0x%02llx to 0x%03llx
 * Added ARM ARM doc number in commit logs wherever referenced.
 * Fixed sysreg.h order in perf_event.c

changes since v4 [4]:
 * Used read/write_sys_reg for pmu register access as per Suzuki's review 
   comment from v2.

   structure as per Mark's review comments.
