[PATCH v3 2/4] x86, boot: PUD VA support for physical mapping (x86_64)

2016-05-03 Thread Thomas Garnier
Minor change that allows early boot physical mapping of PUD level virtual addresses. The current implementation expect the virtual address to be PUD aligned. For KASLR memory randomization, we need to be able to randomize the offset used on the PUD table. It has no impact on current usage.
