[PATCH 0 of 4] x86/mm: Four fixes

[Andres Lagar-Cavilla <andres@lagarcavilla.org>]

In this series we post four patches with bugfixes to p2m, hap, paging and
sharing code:

- Make a few asserts on shared pages type and counts more accurate
 (this time done right, hopefully!)
- Bugfix interactions between the balloon and the paging and sharing
 subsystems. Posted a week ago, probably slipped through the cracks.
- Added a missing sanity check for sharing/paging/access memops.
- Fix vmx_load_pdptrs to crash the guest instead of the host in the
 presence of paged out cr3's.
