Subject[PATCH] mtrr: fix UP breakage caused during switch to stop_machine
While removing custom rendezvous code and switching to stop_machine,
commit 192d8857427d "x86, mtrr: use stop_machine APIs for doing MTRR
rendezvous" completely dropped mtrr setting code on !CONFIG_SMP
breaking MTRR settting on UP. Fix it by removing the incorrect
CONFIG_SMP.
