x86/apic: Only disable CPU x2apic mode when necessary
according to my bisect.
Jiang, Joerg - that commit seems to cause a lockup at suspend time for
me. Now, I haven't verified by reverting it from top-of-git yet, but
the bisection seemed to be pretty stable. I'll try the revert next (it
doesn't revert cleanly, but I can undo it by hand).
Any ideas? The Pixel Chromebook does have an odd and often broken
BIOS/firmware thing, but it *used* to suspend and resume very reliably
once we got around its insane TPM thing.
