Jeremy Fitzhardinge b75fe4e5b8 xen: check EFER for NX before setting up GDT mapping 
x86-64 assumes NX is available by default, so we need to
explicitly check for it before using NX.  Some first-generation
Intel x86-64 processors didn't support NX, and even recent systems
allow it to be disabled in BIOS.

[ Impact: prevent Xen crash on NX-less 64-bit machines ]
