linux-toradex.git/arch/arm/include/asm/pgtable-2level-hwdef.h, branch v3.4.23 Linux kernel for Apalis and Colibri modules ARM: 7077/1: LPAE: Use a mask for physical addresses in page table entries 2011-10-06T14:40:06+00:00 Catalin Marinas catalin.marinas@arm.com 2011-09-05T16:52:36+00:00 d7c5d0dcffb3b5702d9477faceff4b8398e6fed0 With LPAE, the physical address mask is 40-bit while the page table entry is 64-bit. This patch introduces PHYS_MASK for the 2-level page table format, defined as ~0UL. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

entry is 64-bit. This patch introduces PHYS_MASK for the 2-level page
table format, defined as ~0UL.

ARM: 7076/1: LPAE: Add (pte|pmd)val_t type definitions as u32 2011-10-06T14:40:05+00:00 Catalin Marinas catalin.marinas@arm.com 2011-09-05T16:51:56+00:00 442e70c0b3536e832547eed89629435462f4b515 This patch defines the (pte|pmd)val_t as u32 and changes the page table types to be based on these. The PMD bits are converted to the corresponding type using the _AT macro. The flush_pmd_entry/clean_pmd_entry argument was changed to (void *) to allow them to be used with both PGD and PMD pointers and avoid code duplication.
