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.

Athira Rajeev (2):
 powerpc/perf: Expose instruction and data address registers as part of
   extended regs
 tools/perf: Add perf tools support to expose instruction and data
   address registers as part of extended regs

Patchset looks good to me.

Hi Arnaldo,

Requesting for your review on this patchset.

So, this touches the kernel, usually I get a patchkit when the kernel
bits landed, is that the case by now?

Not yet, I'd like some changes to the kernel patch.

cheers
