[Xen-devel] [PATCH v4 00/31] x86: refactor mm.c

[Wei Liu <wei.liu2@xxxxxxxxxx>]

This series is basically all patches in v3 rebased on top of staging, since the
security issues blocking v3 are now published.

I also added BUG() in pv_{alloc,free}_page_type stubs.

The last patch to move the code comment is dropped for now.

The code can be found at:
