[Xen-devel] [PATCH v3 00/21] x86: refactor mm.c (the easy part)

[Wei Liu <wei.liu2@xxxxxxxxxx>]

This series is part of my work to refactor x86/mm.c. It has grown to a 21
patches series so I figure I should probably get them approved first before
making more changes.

What is left is mostly PV MMU hypercall functions and their supporting code.
I'm still thinking about how to refactor those because the helper functions are
a bit convulted. The helper functions are both used by PV MMU code and the
common get / put functions. I think I need to refactor the get / put functions.
If you think there is a better approach please let me know.

The code can be found at:
