As we already have kernel/events/core.c I suggest to put it into
.../common.c?

I planned to factor this out of current perf code for x86 and maybe
other architectures. Want to send separate patches independent from
ibs.

Should I add both functions already to the new file? Maybe this has
some implications to header and makefiles.
