Said tree also cures x86 and folds the SH build fix.
Matt, you said it broke SH completely, but did you try perf stat? perf
record is not supposed to work on SH due to the hardware not having an
overflow interrupt.
Which made me think, what on SH guarantees we update the counter often
enough not to suffer from counter wrap? Would it make sense to make the
SH code hook into their arch tick handler and update the counters from
there?
