2011-12-08	ARM: LPAE: Page table maintenance for the 3-level format	Catalin Marinas
	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>
2011-12-08	ARM: LPAE: Introduce the 3-level page table format definitions	Catalin Marinas
	This patch introduces the pgtable-3level*.h files with definitions specific to the LPAE page table format (3 levels of page tables). Each table is 4KB and has 512 64-bit entries. An entry can point to a 40-bit physical address. The young, write and exec software bits share the corresponding hardware bits (negated). Other software bits use spare bits in the PTE. The patch also changes some variable types from unsigned long or int to pteval_t or pgprot_t. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
