[PATCH 0/5] nds32: Perf support

[Nickhu]

These two commit are perf supporting for nds32.
There are three perfomance counters in nds32, and
each of them can counts different events. You can
use 'perf list' to show the available events that
can be used.

Nickhu (5):
  nds32: Perf porting
  nds32: Fix bug in bitfield.h
  nds32: Add perf call-graph support.
  nds32: Fix perf multiple events map to same counter.
  nds32: Add document for NDS32 PMU.
