[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.

[PATCH] arm64: Fix build due to HMP tracepoints

by Mark Brown

From: Mark Brown <broonie(a)linaro.org> Commit 2353c1f800 (arm: ipi raise/start/end tracing) added tracepoints for IPIs in the generic GIC driver but only added definitions for them on ARM, causing build failures on ARM64. Fix this by adding equivalent definitions for arm64.
