I've ported a couple of patches to the Linux pvops kernel that are necessary
for correctly running domains with paging.  In a nutshell: in the case of a
foreign attempt to map a paged-out page, the correct error code will now be
propogated up to libxc, which will already handle it correctly.

This required an implementation of mmap_batch_v2.

I've tested it using a highly-paged domain and everything looks okay (qemu will
receive the appropriate error via the mmap_batch_v2 and retry).

(My apologies if anyone/everyone receives this set of patches more than once,
I've had some trouble with both my connection dying and guilt freaking out
while I'm sending, leaving things in a bit of an unknown state.)
