Subject: [PATCH 0/9][v5] powerpc/perf: Export memory hierarchy level in Power7/8.

Power7 and Power8 processors save the memory hierarchy level (eg: L2, L3)
from which a load or store instruction was satisfied. Export this hierarchy
information to the user via the perf_mem_data_src object.

Thanks to input from Stephane Eranian, Michael Ellerman, Michael Neuling
and Anshuman Khandual.

Sukadev Bhattiprolu (9):
  powerpc/perf: Rename Power8 macros to start with PME
  powerpc/perf: Export Power8 generic events in sysfs
  powerpc/perf: Add Power8 event PM_MRK_GRP_CMPL to sysfs.
  powerpc: Rename branch_opcode() to instr_opcode()
  powerpc: implement is_instr_load_store().
  powerpc/perf: Define big-endian version of perf_mem_data_src
  powerpc/perf: Export Power8 memory hierarchy info to user space.
  powerpc/perf: Export Power7 memory hierarchy info to user space.
  powerpc/perf: Update perf-mem man page for Power
