// CC Stephane for RAPL related bug

Bjorn, sorry this bug report is mis-titled. The only new bug that show
up in aa11fc58dc is on rapl_pmu_init. And it shows up only 1 time, so
it's hard to reproduce and the bisect is likely not accurate.  I'll
retry the bisect with more repeat count. Sorry for the disturbing!
