[PATCH v2 01/22] ARM: add mechanism for late code patching

2012-08-10 Thread Cyril Chemparathy
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
