[RFC PATCH 0/4] Big Endian support for ARM64 kernel

by Ankit Jindal

This patchset adds support for using Big Endian mode of AArch64 CPUs All patches have been tested on APM X-Gene Storm SOC. The Big Endian toolchain used for development can be found at: http://cbuild.validation.linaro.org/snapshots/big_endian We have tested both 32bit BE and 64bit BE root filesystems with these patches. The 64bit BE root filesystem was build manually using busybox-1.21.1 and above mentioned toolchain. The 32bit BE root filesystem was readily available from Linaro releases located at: http://snapshots.linaro.org/openembedded/images Ankit Jindal (4): ARM64: Add Kconfig option to enable Big Endian kernel ARM64: Include appropriate byteorder for Big Endian ARM64: Big Endian fixes for kernel booting ARM64: Support for 32-bit big endian userspace arch/arm64/Kconfig | 2 ++ arch/arm64/Makefile | 7 +++++++ arch/arm64/include/asm/assembler.h | 7 +++++++ arch/arm64/include/asm/processor.h | 3 +++ arch/arm64/include/uapi/asm/byteorder.h | 4 ++++ arch/arm64/kernel/head.S | 34 +++++++++++++++++++++++++++++++ arch/arm64/kernel/setup.c | 19 +++++++++++++---- arch/arm64/kernel/signal32.c | 4 ++++ arch/arm64/kernel/smp_spin_table.c | 5 +++-- arch/arm64/mm/Kconfig | 7 +++++++ arch/arm64/mm/proc.S | 2 +- 11 files changed, 87 insertions(+), 7 deletions(-) create mode 100644 arch/arm64/mm/Kconfig -- 1.7.9.5

[PATCH v2] ARM: cci driver need big endian fixes in asm code

by Victor Kamensky

Hi All, This is version 2 of cci big endian fix. Idea of this way of fixing was suggested by Ben Dooks [1]. Compared to previous solution this one does not use ifdefs and looks much cleaner. This was tested on TC2 both LE and BE, CONFIG_ARM_CCI was enabled. [1] http://lists.infradead.org/pipermail/linux-arm-kernel/2013-October/203248.h… Thanks, Victor Victor Kamensky (1): ARM: cci driver need big endian fixes in asm code drivers/bus/arm-cci.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) -- 1.8.1.4

[PATCH 0/5] edac, highbank: Add Calxeda ECX-2000 support

by Robert Richter

This patch series enables ECC edac support for Calxeda ECX-2000 (Midway). The ECX-2000 memory controller is similar to Highbank but has different register bases for error and interrupt registers. Testing the driver uncovered a bug in the interrupt initialization. So there is also a fix for this for all the Highbank edac drivers. The interrupt was enabled too early which caused a crash if there are interrupts pending (ECC errors) during driver initialization. Also some improvements and unification of edac log messages I found useful. -Robert Rob Herring (1): ARM: dts: calxeda: move memory-controller node out of ecx-common.dtsi Robert Richter (4): edac, highbank: Fix interrupt setup of mem and l2 controller edac, highbank: Add Calxeda ECX-2000 support edac, highbank: Improve and unify naming edac: Unify reporting of device info for device, mc and pci .../devicetree/bindings/arm/calxeda/mem-ctrlr.txt | 4 +- arch/arm/boot/dts/ecx-2000.dts | 6 + arch/arm/boot/dts/ecx-common.dtsi | 6 - arch/arm/boot/dts/highbank.dts | 6 + drivers/edac/edac_device.c | 9 +- drivers/edac/edac_mc.c | 6 +- drivers/edac/edac_pci.c | 8 +- drivers/edac/highbank_l2_edac.c | 33 +++--- drivers/edac/highbank_mc_edac.c | 128 +++++++++++++-------- 9 files changed, 127 insertions(+), 79 deletions(-) -- 1.8.4.rc3

[PATCH] ARM: trace: Add tracepoint for the Inter Processor Interrupt

by Daniel Lezcano

The Inter Processor Interrupt is used on ARM to tell another processor to do a specific action. This is mainly used to emulate a timer interrupt on an idle cpu, force a cpu to reschedule or run a function on another processor context. Add a tracepoint when raising an IPI and in the entry/exit handler function.
