Subject: [PATCHSET/RFC 0/2] perf: Fix issues reported by perf fuzzer

hi,
Vince reported several issues with perf code hit by perf fuzzer,
in here:
  http://marc.info/?l=linux-kernel&m=141806390822670&w=2

I run the fuzzer, but wasn't able to hit issues reported
by Vince. But.. I was lucky enough to hit other 2 issues
described in following patches ;-)

As I dont follow the uncore code much, it is sort of RFC
patchset. However I'm running the fuzzer now for several
hours and can't hit any other issue.

thanks,
jirka
