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 (10):
  powerpc: Rename branch_opcode() to instr_opcode()
  powerpc/Power7: detect load/store instructions
  tools/perf: silence compiler warnings
  tools/perf: Remove local byteorder.h.
  powerpc/perf: Remove PME_ prefix for power7 events
  powerpc/perf: Export Power8 generic events in sysfs
  powerpc/perf: Add Power8 event PM_MRK_GRP_CMPL to sysfs.
  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.
