Yeah, the other one is in i386 headers, so We probably wan't to leave
it there. One option is to move get_cycles_sync to x86_64 headers, and
then #ifdef just the offending part.

Although the operation consists in reading tscp. I choose this to be
consistent with i386, but I have no special feelings about it. I'm
okay with changing it if you prefer.
