ARM: LPAE: Page table maintenance for the 3-level format
This patch modifies the pgd/pmd/pte manipulation functions to support the 3-level page table format. Since there is no need for an 'ext' argument to cpu_set_pte_ext(), this patch conditionally defines a different prototype for this function when CONFIG_ARM_LPAE. The patch also introduces the L_PGD_SWAPPER flag to mark pgd entries pointing to pmd tables pre-allocated in the swapper_pg_dir and avoid trying to free them at run-time. This flag is 0 with the classic page table format. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
