[V4 0/2] tools/perf: Add instruction and data address registers to extended regs in powerpc

[Athira Rajeev]

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 refactors the existing macro definition of
PERF_REG_PMU_MASK_300 and PERF_REG_PMU_MASK_31 to make it more
readable.
Patch 2/2 includes perf tools side changes to add the SPRs to
sample_reg_mask to use with -I? option.

Changelog:
Change from v3 -> v4:
- Spilt tools side patches separately since kernel side
  changes are in powerpc/next. There is no code wise changes
  from v3.

  Kernel patches are taken to powerpc/next:
  [1/4] powerpc/perf: Refactor the code definition of perf reg extended mask
  https://git.kernel.org/powerpc/c/02b182e67482d9167a13a0ff19b55037b70b21ad
  [3/4] powerpc/perf: Expose instruction and data address registers as part of extended regs
  https://git.kernel.org/powerpc/c/29908bbf7b8960d261dfdd428bbaa656275e80f3

Change from v2 -> v3:
Addressed review comments from Michael Ellerman
- Fixed the macro definition to use "unsigned long long"
  which otherwise will cause build error with perf on
  32-bit.
- Added Reviewed-by from Daniel Axtens for patch3.

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.

Athira Rajeev (2):
  tools/perf: Refactor the code definition of perf reg extended mask in
    tools side header file
  tools/perf: Add perf tools support to expose instruction and data
    address registers as part of extended regs
