Changes since v5:
- Fix compilation on ARM

This was the removal of some spurious "&", I think?

Yeah, I forgot to keep the macro's in sync. ARM also needed the xen/percpu.h 
header file to be
explictly included into spinlock.h.

Thanks for catching this!

Sorry for not build testing before on ARM. Building the hypervisor itself using 
a prebuilt linaro
toolchain is actually very easy (no chroot required).

Do you think it's worth documenting this? So that at least hypervisor build 
failures are caught.


This is already documented (briefly) here:
