    powerpc/perf: Update perf_regs structure to include MMCRA · 6529870c
    Madhavan Srinivasan authored
    On each sample, Monitor Mode Control Register A (MMCRA) content is
    saved in pt_regs. MMCRA does not have a entry as-is in the pt_regs but
    instead, MMCRA content is saved in the "dsisr" register of pt_regs.
    
    Patch adds another entry to the perf_regs structure to include the
    "MMCRA" printing which internally maps to the "dsisr" of pt_regs.
    
    It also check for the MMCRA availability in the platform and present
    value accordingly
    
    mpe: This was the 2nd patch in a series with commit 333804dc
    
    
    ("powerpc/perf: Update perf_regs structure to include SIER") but I
    accidentally only merged the 1st patch, so merge this one now.
