Patch set adds PMU registers namely Sampled Instruction Address Register
(SIAR) and Sampled Data Address Register (SDAR) as part of extended regs
in PowerPC. These registers provides the instruction/data address and
adding these to extended regs helps in debug purposes.
Patch 1/2 adds SIAR and SDAR as part of the extended regs mask.
Patch 2/2 includes perf tools side changes to add the SPRs to
sample_reg_mask to use with -I? option.
