[PATCH V3 1/3] perf/powerpc:add ability to sample intr machine state in power

The enum definition assigns an 'id' to each register in "struct pt_regs" of arch/powerpc.The order of these values in the enum definition are based on the corresponding macros in arch/powerpc/include/uapi/asm/ptrace.h . Signed-off-by: Anju T <a...@linux.vnet.ibm.com> --- arch

[PATCH V3 3/3] tools/perf:Map the ID values with register names
