MIPS hardware performance counters may have either 32-bit or 64-bit
wide counter registers.  The current implementation only supports the
32-bit variety.

These patches aim to add support for 64-bit wide counters while
mantaining support for 32-bit.

Changes from v1:

o Removed Octeon processor support to a separate patch set.

o Rebased against v5 of Deng-Cheng Zhu's cleanups:
      http://patchwork.linux-mips.org/patch/2011/
      http://patchwork.linux-mips.org/patch/2012/
      http://patchwork.linux-mips.org/patch/2013/
      http://patchwork.linux-mips.org/patch/2014/
      http://patchwork.linux-mips.org/patch/2015/

o Tried to fix problem where 32-bit counters generated way too many
  interrupts.

David Daney (4):
  MIPS: Add accessor macros for 64-bit performance counter registers.
  MIPS: perf: Cleanup formatting in arch/mips/kernel/perf_event.c
  MIPS: perf: Reorganize contents of perf support files.
  MIPS: perf: Add support for 64-bit perf counters.
