[Xen-devel][PATCH] Fix the NX bit support issue for PAE/64bit guest on x86-64

["Xin, Xiaohui" <xiaohui.xin@xxxxxxxxx>]

With this patch, the PAE/64bit guest on x86-64 can support NX bit successfully.

The PAE guest can run on SMP 64-bit Xen0 now.

And it optimizes the save/restore action for EFER MSR during the context switch.
