[PATCH 0/8][v4] powerpc/perf: Export memory hierarchy level in Power7/8.

[Sukadev Bhattiprolu <sukadev@linux.vnet.ibm.com>]

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.

Sukadev Bhattiprolu (8):
  powerpc/perf: Rename Power8 macros to start with PME
  powerpc/perf: Export Power8 generic events in sysfs
  powerpc/perf: Add PM_MRK_GRP_CMPL event to sysfs.
  powerpc/perf: Define big-endian version of perf_mem_data_src
  powerpc/perf: Export Power8 memory hierarchy info to user space.
  powerpc: Rename branch_opcode() to instr_opcode()
  power: implement is_instr_load_store().
  powerpc/perf: Export Power7 memory hierarchy info to user space.
