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 1/4 and 2/4 refactors the existing macro definition of
PERF_REG_PMU_MASK_300 and PERF_REG_PMU_MASK_31 to make it more
readable.
Patch 3/4 adds SIAR and SDAR as part of the extended regs mask.
Patch 4/4 includes perf tools side changes to add the SPRs to
sample_reg_mask to use with -I? option.
Changelog:
Change from v1 -> v2:
Addressed review comments from Michael Ellerman
- Refactored the perf reg extended mask value macros for
PERF_REG_PMU_MASK_300 and PERF_REG_PMU_MASK_31 to
make it more readable. Also moved PERF_REG_EXTENDED_MAX
along with enum definition similar to PERF_REG_POWERPC_MAX.
