that's due to the changes in tip/x86/apic and in tip/x86/uv.

ok, i've just merged x86/apic into x86/x2apic and x86/uv as well, and
pushed out the result.

Note: it's a first raw merge and completely untested. It will now merge
cleanly into tip/master. There are probably a few details missing.

The smp-alternatives based trick that Maciej applied for write-around
can stay in the mem_apic_* methods - modern APICs do not need any
workaround in this area and can just use apic_ops.
