[GIT PULL v2] ARM: probes: big-endian support

by Taras Kondratiuk

Hi Russell, Please pull fixes for ARM kprobes/uprobes big-endian support. It is reworked initial Ben's series for big endian support [1]. Dropped patches that are not directly related to probes and rebased series on top of Dave Long's ARM uprobes series. Current set of patches is enough to have functional BE kprobes and uprobes. One ARM kprobe test fails on Cortex-A15 boards (TC2 and Keystone2 EVM), while it passes on Pandaboard. The issue is not related to this series and already present since v3.13-rc7. v1..v2: Rebased series on top of Dave Long's ARM uprobes series. Now this series fixes both BE kprobes and BE uprobes. Tested on Pandaboard ES and TI Keystone2 EVM. pull req v1: http://www.spinics.net/lists/arm-kernel/msg300227.html [1] http://www.spinics.net/lists/arm-kernel/msg285210.html --->8 The following changes since commit c7edc9e326d53ca5ef9bed82de0740c6b107d55b: ARM: add uprobes support (2014-03-18 16:39:40 -0400) are available in the git repository at: git://git.linaro.org/people/taras.kondratiuk/linux.git tags/for_russell/arm-be-probes for you to fetch changes up to 41b5368f31f86a1c2be2bb16a1cf18d23f1223d4: ARM: kprobes-test: Workaround GAS .align bug (2014-04-01 16:48:27 +0300) ---------------------------------------------------------------- Ben Dooks (4): ARM: probes: fix instruction fetch order with <asm/opcodes.h> ARM: kprobes-test: use <asm/opcodes.h> for instruction accesses ARM: kprobes-test: use <asm/opcodes.h> for ARM instruction building ARM: kprobes-test: use <asm/opcodes.h> for Thumb instruction building Taras Kondratiuk (1): ARM: kprobes-test: Workaround GAS .align bug arch/arm/kernel/kprobes-common.c | 4 +- arch/arm/kernel/kprobes-test-arm.c | 603 +++++++++++++++++----------------- arch/arm/kernel/kprobes-test-thumb.c | 447 ++++++++++++------------- arch/arm/kernel/kprobes-test.c | 13 +- arch/arm/kernel/kprobes-test.h | 2 +- arch/arm/kernel/kprobes-thumb.c | 20 +- arch/arm/kernel/kprobes.c | 9 +- arch/arm/kernel/probes.c | 15 +- 8 files changed, 562 insertions(+), 551 deletions(-) -- Taras Kondratiuk

[LSK-testing PATCH 0/7] thermal framework DT testing

by Alex Shi

This patchset reflect the DT changes for thermal framework change on omap4 board, more specific, on panda ES board. It is used for thermal framework testing to approve new thermal framework backport is working. The patchset is on git://git.linaro.org/kernel/linux-linaro-stable.git thermal-framework-test Haojian give me lots help to find out missed patches. Thanks a lot! Any comments are appreciated! Thanks Alex [PATCH 1/7] arm: dts: add omap4 CPU thermal data [PATCH 2/7] arm: dts: add omap4460 thermal data [PATCH 3/7] ARM: omap dts syntax error fix [PATCH 4/7] arm: dts: make OMAP4460 bandgap node to belong to OCP [PATCH 5/7] ARM: 7758/1: introduce config HAS_BANDGAP [PATCH 6/7] arm: dts: add cooling properties on omap4460 cpu node [PATCH 7/7] thermal: ti-soc-thermal: use standard GPIO DT bindings
