This series is a follow on to the RFC series posted earlier (archived at [1]).
The major change introduced here is the modification to the kernel patching
mechanism for phys_to_virt/virt_to_phys, in order to support LPAE platforms
that require late patching.  In addition to these changes, we've updated the
series based on feedback from the earlier posting.

Most of the patches in this series are fixes and extensions to LPAE support on
ARM. The last three patches in this series are specific to the TI Keystone
platform, and are being provided here for the sake of completeness.  These
three patches are dependent on the smpops patch set (see [2]), and are not
ready to be merged in as yet.

Can you explain why you want the kernel loaded above the 4GB watermark?
This seems silly to me, as the kernel needs to run at points with a 1:1
physical to virtual mapping, and you can't do that if the kernel is
stored in physical memory above the 4GB watermark.
