[Xen-changelog] [xen-unstable] libxc header fixups.

# HG changeset patch
# User Emmanuel Ackaouy <ack@xxxxxxxxxxxxx>
# Date 1169763412 0
# Node ID 50d9e2ddc377a746eb094578b264bba67045cbce
# Parent  985384fd424cd3192c14399d6df31a648b8eebb2
libxc header fixups.

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.
