[PATCH 0/1] perf/x86: Fix time_shift in perf_event_mmap_page

[Adrian Hunter <adrian.hunter@intel.com>]

Hi

There is a problem with my patch:
commit b20112edeadf ("perf/x86: Improve accuracy of perf/sched clock")
which is in tip at the moment.

The problem is that userspace does not expect time_shift in perf_event_mmap_page
to be as much as 32.  Here is a proposed fix.
