[Xen-devel] [PATCH v3 extra 00/11] x86: refactor mm.c: page APIs and hypercalls

[Wei Liu <wei.liu2@xxxxxxxxxx>]

This series is built on top of the "easy part" [0] (and rebased on top of
current staging).

After discussing with George and Andrew on IRC, it is clear that
alloc_page_type and free_page_type are only useful for PV guests. This
immediately enables us to move them and the supporting code to PV directory.

Note that in the stubs I choose to return EINVAL but maybe we should just BUG()
there because those paths aren't supposed to be taken when !CONFIG_PV. And I'm
sure common code will BUG_ON() or BUG() sooner or later. Thoughts?

PV MMU hypercalls are moved to mm-hypercalls.c to avoid having a very huge
pv/mm.c.
