Ugh, I misread .Ldefault_entry in head_32.S, it skips over the entire EFER code
if PAE=0. Apparently I didn't test this with non-PAE paging and EPT?
Paolo, I'll send a revert since it's in kvm/next, but even better would be if
you can drop the patch :-) Lucky for me you didn't pick up patch 4/4 that
depends on this...
I'll revisit this mess in a few weeks.
Rather, let's keep this, see if anyone complains and possibly add a
"depends on X86_PAE || X86_64" to KVM.
