[Qemu-devel] [PATCH 0/6] Multi-level page tables and userland mapping fixes, v3

[Richard Henderson <rth@twiddle.net>]

Changes since v2:
  * Fix two errors pointed out by pbrook: l1_map size in system mode,
    and h2g_valid definition for 64-on-32-bit.
  * Assertions that addresses are not outside the bounds of the 
    guest address space.
  * Re-base vs master, after l1_map_phys changes.
