From e41ceed035966d593ae34c3de33924965a6b9fba Mon Sep 17 00:00:00 2001 From: Jungseok Lee Date: Mon, 12 May 2014 10:40:38 +0100 Subject: arm64: Introduce VA_BITS and translation level options This patch adds virtual address space size and a level of translation tables to kernel configuration. It facilicates introduction of different MMU options, such as 4KB + 4 levels, 16KB + 4 levels and 64KB + 3 levels, easily. The idea is based on the discussion with Catalin Marinas: http://www.spinics.net/linux/lists/arm-kernel/msg319552.html Signed-off-by: Jungseok Lee Reviewed-by: Sungjinn Chung Acked-by: Kukjin Kim Reviewed-by: Christoffer Dall Signed-off-by: Catalin Marinas Tested-by: Jungseok Lee --- arch/arm64/include/asm/pgtable-hwdef.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'arch/arm64/include/asm/pgtable-hwdef.h') diff --git a/arch/arm64/include/asm/pgtable-hwdef.h b/arch/arm64/include/asm/pgtable-hwdef.h index 955e8c5f0afb..c7c603b489b8 100644 --- a/arch/arm64/include/asm/pgtable-hwdef.h +++ b/arch/arm64/include/asm/pgtable-hwdef.h @@ -16,7 +16,7 @@ #ifndef __ASM_PGTABLE_HWDEF_H #define __ASM_PGTABLE_HWDEF_H -#ifdef CONFIG_ARM64_64K_PAGES +#ifdef CONFIG_ARM64_2_LEVELS #include #else #include -- cgit v1.2.3
