Revert "[PATCH] x86-64: fix x86_64-mm-sched-clock-share"

This reverts commit 184c44d2049c4db7ef6ec65794546954da2c6a0e.

As noted by Dave Jones:
   "Linus, please revert the above cset.  It doesn't seem to be
    necessary (it was added to fix a miscompile in 'make allnoconfig'
    which doesn't seem to be repeatable with it reverted) and actively
   breaks the ARM SA1100 framebuffer driver."
