The pvhvm drivers had a few minor adjustments made to them on their way
upstream, pull them back into xen.git for consistency.

Updated with 3 new PVHVM changesets which went upstream recently.

32-bit is currently failing to build, compaining about:

  LD      .tmp_vmlinux1
arch/x86/built-in.o: In function `xen_hvm_callback_vector':
/home/jeremy/git/linux/arch/x86/kernel/entry_32.S:1092: undefined reference to `smp_xen_hvm_callback_vector'

I'm pretty sure this used to work, so I suspect this set of changes
caused the problem, but I haven't actually narrowed it down.

One thing I noticed is that all the other invocations of
BUILD_INTERRUPT() are in entry_arch.h, so we should probably normalize that.

I'll have a look at this later this afternoon if the thing I'm currently
working on works out with no unexpected problems...
