Following this email there are two patches that fix this potential privilege
escalation issue.  It looks like the issue has been in the kernel since 3.2 but
has became exploitable on 3.11 -RCs only.

Stephen Boyd (1):
  ARM: 7810/1: perf: Fix array out of bounds access in
    armpmu_map_hw_event()

Will Deacon (1):
  ARM: 7809/1: perf: fix event validation for software group leaders
