Mark Salter	bec7cedc8a	arm64: export __cpu_{clear,copy}_user_page functions ... The __cpu_clear_user_page() and __cpu_copy_user_page() functions are not currently exported. This prevents modules from using clear_user_page() and copy_user_page().

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.
