Several issues were found in the implementation and these two patches were created to address those issues. These patches were originally posted as part of the larger TrenchBoot patch set but are now being posted separately since they can be merged independently of the TrenchBoot work. Changes in v2: - Add checks and failure modes for when early_memremap and memremap fail. - Fix variable declarations to use reverse fir tree format. - Use local indirect variable and remove all the inline casts. - Misc. fixes to the commit messages.
