[Xen-devel] [PATCH] Abstract writes to phys_to_machine_mapping

[Jacob Gorm Hansen <jacobg@xxxxxxx>]

hi,

for my self-migration patch, I need the ability to trap writes to the
p2m map during migration, because I keep a dictionary mapping mfns to
pfns, which I use for remapping the page tables once I am on the other
side.

The attached patch abstracts writes through an inline function defined
in page.h.
