Subject: [PATCH v4 00/13] ARM LPAE Fixes - Part 1

This series is a repost of the LPAE related changes in preparation for the
introduction of the Keystone sub-architecture.  The original series has now
been split, and this particular series excludes the earlier changes to the
runtime code patching implementation.  Earlier versions of this series can be
found at [1], [2], [3] and [4].

These patches are also available in git:
