[Xen-devel] [PATCH v5 1/7] x86: move some xen mm function declarations

[Hongyan Xia <hongyxia@xxxxxxxxxx>]

From: Wei Liu <wei.liu2@xxxxxxxxxx>

They were put into page.h but mm.h is more appropriate.

The real reason is that I will be adding some new functions which
takes mfn_t. It turns out it is a bit difficult to do in page.h.

No functional change.

Changed since v3:
- move Xen PTE API declarations next to do_page_walk().
