[Xen-devel] [patch 07/10] libxc header fixups.

[Gerd Hoffmann <kraxel@xxxxxxxxxx>]

Make some arch-specific #defines for page table handling
available unconditionally, add a suffix to avoid name clashes.

The versions without suffix are defined depending on the
architecture like they used to, so code using them continues
to work.
