[PATCH v3 01/17] ARM: add mechanism for late code patching

The original phys_to_virt/virt_to_phys patching implementation relied on early patching prior to MMU initialization. On PAE systems running out of >4G address space, this would have entailed an additional round of patching after switching over to the high address space. The approach implemented h
