Following text might have a better reference to the current problem:

Currently vunmap() is called from  from xen/arch/arm/cpuerrata.c with an
address potentially not page aligned. Instead of fixing that in ARM code,
we let vunmap() making alignment by itself and stripping other existing
vunmap() calls from prior masking. This makes it consistent with how
{,un}map_domain_page() currently works.

With the main change, also:
 - replace opencoded PAGE_MASK macro in vm_index()
