[PATCH V7 2/4] perf/powerpc: add support for sampling intr machine state

2016-01-06 Thread Anju T
The perf infrastructure uses a bit mask to find out valid registers to display. Define a register mask for supported registers defined in asm/perf_regs.h. The bit positions also correspond to register IDs which is used by perf infrastructure to fetch the register values. CONFIG_HAVE_PERF_REGS
