Mark Rutland	883d50a0ed	arm64: simplify pgd_alloc ... Currently pgd_alloc has a redundant NULL check in its return path that can be removed with no ill effects. With that removed it's also possible to return early and eliminate the new_pgd temporary variable. This patch applies said modifications, making the logic of pgd_alloc correspond 1-1 with that of pgd_free.

Catalin Marinas	1d18c47c73	arm64: MMU fault handling and page table management ... This patch adds support for the handling of the MMU faults (exception entry code introduced by a previous patch) and page table management. The user translation table is pointed to by TTBR0 and the kernel one (swapper_pg_dir) by TTBR1. There is no translation information shared or address space overlapping between user and kernel page tables.
