x86/xen/gdt: Use X86_FEATURE_XENPV instead of globals for the GDT fixup
Xen imposes special requirements on the GDT. Rather than using a global variable for the pgprot, just use an explicit special case for Xen -- this makes it clearer what's going on. It also debloats 64-bit kernels very slightly.
