perf/x86: Fix incorrect use of do_div() in NMI warning
I completely botched understanding the calling conventions of do_div(). I assumed that do_div() returned the result instead of realizing that it modifies its argument and returns a remainder. The side-effect from this would be bogus numbers for the "msecs" value in the warning messages: INFO: NMI handler (perf_event_nmi_handler) took too long to run: 0.114 msecs Note, there was a second fix posted by Stephane Eranian for a separate patch which I also botched: http://lkml.kernel.org/r/20130704223010.GA30625@quad Signed-off-by: Dave Hansen <dave.hansen@linux.intel.com> Cc: Dave Hansen <dave@sr71.net> Link: http://lkml.kernel.org/r/20130708214404.B0B6EA66@viggo.jf.intel.com Signed-off-by: Ingo Molnar <mingo@kernel.org>
