2012-01-27Merge branch 'perf/fast' into perf/coreIngo Molnar1-2/+0
Merge reason: Lets ready it for v3.4 Signed-off-by: Ingo Molnar <mingo@elte.hu>
2011-12-21perf, arch: Rework perf_event_index()Peter Zijlstra1-2/+0
Put the logic to compute the event index into a per pmu method. This is required because the x86 rules are weird and wonderful and don't match the capabilities of the current scheme. AFAIK only powerpc actually has a usable userspace read of the PMCs but I'm not at all sure anybody actually used that. ARM is restored to the default since it currently does not support userspace access at all. And all software events are provided with a method that reports their index as 0 (disabled).

2011-11-25lib: move GENERIC_IOMAP to lib/KconfigMichael S. Tsirkin1-3/+1
define GENERIC_IOMAP in a central location instead of all architectures. This will be helpful for the follow-up patch which makes it select other configs. Code is also a bit shorter this way. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
