byteorder.h when
Implement is_instr_load_store() to detect whether a given instruction
is one of the fixed-point or floating-point load/store instructions.
This function will be used in a follow-on patch to save memory hierarchy
information of the load/store.

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.

We use helpers like GENERIC_EVENT_ATTR() to list the generic events in
sysfs. To avoid name collisions, GENERIC_EVENT_ATTR() requires the perf
event macros to start with PME.

bits in the SIER to identify load/store operations and hence don't need a
similar functionality).

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
The uninitialized variables cause warnings which are treated as errors
during build (without WERROR=0).
