This patch series include two parts:
1. Patch1-2 use dummy STE tables with "ste abort" hardware feature to abort unexpected
devices accessing. For more details, see the description in patch 2.
2. If the "ste abort" feature is not support, force the unexpected devices in the
secondary kernel to use the memory maps which it used in the first kernel. For more
details, see patch 5.
