Subject: [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 .
