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.
