[PATCH v2 0/6] ARM: mm: Extend the runtime patch stub for PAE systems

[Santosh Shilimkar]

This is version 2 of the series which addresses the comments/suggestions
we received on earlier version. The series trying to extend the existing
v2p runtime patching for LPAE machines which can have physical memory
beyond 4 GB. Keystone is one such ARM machine.

In testing various modes(LPAE/non-LPAE, ARM/THMUB), we found an issue
with the patching code for THUMB2 build. So there is a patch added in
the series to address it. I was planning to squash it in the parent
64 bit patch but thought of keeping it separate for ease of review.
We can squash it while merging the patches. 

Special thanks to Nicolas for his valuable feedback on the earlier
version.
