SubjectRe: [GIT PULL] perf changes for v3.8
Hmm. This may be entirely unrelated to this particular pull request, but

perf record -e cycles:pp

no longer works on my westmere machine (Operation not supported). It
used to work, but I haven't tried to bisect it, since I hope somebody
will just go "oh, I know what's up".

dmesg says:

Performance Events: PEBS fmt1+, 16-deep LBR, Westmere events, Intel
PMU driver.
perf_event_intel: CPUID marked event: 'bus cycles' unavailable
... version: 3
... bit width: 48
... generic registers: 4
... value mask: 0000ffffffffffff
... max period: 000000007fffffff
... fixed-purpose events: 3
... event mask: 000000070000000f

Any ideas?

Linus
