with ARMv6, the CPUs support the BE-8 variant of big-endian (byte-invariant). This patch adds the core support: - setting of the BE-8 mode via the CPSR.E register for both kernel and user threads - big-endian page table walking - REV used to rotate instructions read from memory during fault processing as they are still little-endian format - Kconfig and Makefile support for BE-8. The --be8 option must be passed to the final linking stage to convert the instructions to little-endian Signed-off-by: Catalin Marinas --- arch/arm/Makefile | 3 +++ arch/arm/boot/compressed/Makefile | 5 ++++- arch/arm/boot/compressed/head.S | 6 ++++++ arch/arm/include/asm/processor.h | 1 + arch/arm/include/asm/ptrace.h | 10 ++++++++++ arch/arm/kernel/entry-armv.S | 3 +++ arch/arm/kernel/entry-common.S | 3 +++ arch/arm/kernel/process.c | 2 +- arch/arm/mm/Kconfig | 14 ++++++++++++++ arch/arm/mm/abort-ev6.S | 3 +++ arch/arm/mm/proc-v6.S | 3 +++ arch/arm/mm/proc-v7.S | 3 +++ 12 files changed, 54 insertions(+), 2 deletions(-) diff --git a/arch/arm/Makefile b/arch/arm/Makefile index e84729bf13d4..1167a4e8c7a8 100644 --- a/arch/arm/Makefile +++ b/arch/arm/Makefile @@ -11,6 +11,9 @@ # Copyright (C) 1995-2001 by Russell King LDFLAGS_vmlinux :=-p --no-undefined -X +ifeq ($(CONFIG_CPU_ENDIAN_BE8),y) +LDFLAGS_vmlinux += --be8 +endif CPPFLAGS_vmlinux.lds = -DTEXT_OFFSET=$(TEXT_OFFSET) OBJCOPYFLAGS :=-O binary -R .note -R .note.gnu.build-id -R .comment -S GZFLAGS :=-9 diff --git a/arch/arm/boot/compressed/Makefile b/arch/arm/boot/compressed/Makefile index fbe5eef1f6c9..ce39dc540085 100644 --- a/arch/arm/boot/compressed/Makefile +++ b/arch/arm/boot/compressed/Makefile @@ -40,7 +40,7 @@ ifeq ($(CONFIG_PXA_SHARPSL),y) OBJS += head-sharpsl.o endif -ifeq ($(CONFIG_CPU_BIG_ENDIAN),y) +ifeq ($(CONFIG_CPU_ENDIAN_BE32),y) ifeq ($(CONFIG_CPU_CP15),y) OBJS += big-endian.o else @@ -78,6 +78,9 @@ EXTRA_AFLAGS := -Wa,-march=all # linker symbols.

The main problem is that the faulty instruction (which needs to be emulated in software) will be restarted several times (normally until a context switch disables the VFP). This patch ensures that the VFP exception is treated as synchronous.
