[PATCH 01/13] perf, x86: Fix Nehalem PMU quirk
The idea was to run all three counters, which means we need to program 7 into the enable mask, not 3 (which is two bits).

[PATCH 05/13] perf, powerpc: Convert the FSL driver to use local64_t

[RFC][PATCH 00/13] perf pmu interface changes -v3
The first 5 patches are fixes to the existing code and should probably end up in .35, Dave has his sparc64 fix already queued I think, Paulus could you take the FSL fixes? The rest of these patches prepare the perf code for multiple pmus (no user interface yet, Lin Ming is working on that). These patches remove ... 9 Jul 2010 05:04
