perf/x86/intel: Disable userspace RDPMC usage for large PEBS
So this whole commit log is about disabling RDPMC usage for "large PEBS"
but the actual change disables RDPMC if "PERF_X86_EVENT_FREERUNNING"
Either the commit log is really misleading, or else a poor name was chosen
for this feature.
Its the same thing, and yes that might want renaming I suppose.
Yes, I will send a patch to rename the "FREERUNNING" to "LARGE_PEBS",
and fix the confusion.
Thanks,
Kan
