Don't attempt to use clflush on the local APIC register window. Various
CPUs exhibit bad behavior if this is done (Intel Errata AAJ3, hangs on
Pentium-M, and trashing of the local APIC registers on a VIA C7). The
local APIC is implicitly mapped UC already via MTRRs, so the clflush isn't
necessary anyway.
