[PATCH v4 0/5] MIPS/Perf-events: Sync with mainline upper layer (v4)

[Deng-Cheng Zhu <dengcheng.zhu@gmail.com>]

Current MIPS Perf-events uses older interfaces to the generic layer. So it
will not work. This patch set fixes this issue (reported by Wu Zhangjin) by
adding MIPS counterparts for a list of previous commits that went to
mainline earlier.

Changes:
v4 - v3:
o Rebase this patch set to have early_initcall instead of arch_initcall for
init_hw_perf_events.
o Change the arguments of perf_pmu_register() in Patch #2.
v3 - v2:
o Keep all mentioned commits in the form of number + title + original
summary + (MIPS specific info when needed).
v2 - v1:
o Corrected the return value of the event check in validate_event().

  MIPS/Perf-events: Fix event check in validate_event()
  MIPS/Perf-events: Work with the new callchain interface
  MIPS/Perf-events: Use unsigned delta for right shift in event update
