| * | arm: Fix build error with context tracking callsFrederic Weisbecker2013-09-271-4/+4
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ad65782fba50 (context_tracking: Optimize main APIs off case with static key) converted context tracking main APIs to inline function and left ARM asm callers behind. This can be easily fixed by making ARM calling the post static keys context tracking function. We just need to replicate the static key checks there. We'll remove these later when ARM will support the context tracking static keys.

| | | | | | | | | | | | | | | | | | | | | | | | | | Patch 638591c enabled building the AES assembler code in Thumb2 mode. However, this code used arithmetic involving PC rather than adr{l} instructions to generate PC-relative references to the lookup tables, and this needs to take into account the different PC offset when running in Thumb mode.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 377747c40657 ("ARM: entry: allow ARM-private syscalls to be restarted") reworked the low-level syscall dispatcher to allow restarting of ARM-private syscalls. Unfortunately, this relocated the label used to dispatch a private syscall from the trace path, so that the invocation would be bypassed altogether! This causes applications to fail under strace as soon as they rely on a private syscall (e.g. set_tls): set_tls(0xb6fad4c0, 0xb6fadb98, 0xb6fb1050, 0xb6fad4c0, 0xb6fb1050) = -1 ENOSYS (Function not implemented) This patch fixes the label so that we correctly dispatch private syscalls from the trace path.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit cdc58d602d2e657602a90c190cbf745886c95977 "cpufreq: imx6q-cpufreq: remove device tree parsing for cpu nodes" assumed the pdev->dev is set to cpu0 device in the platform code. But it actually points to the virtual cpufreq-cpu0 platform device which is not present in the device tree. Most of the information needed by cpufreq is stored in cpu0 DT node. So cpu_dev must point to cpu0 device. This patch fixes the wrong assignment to cpu_dev.

That caused the WLAN to stop working as the related .dts entries fell through the cracks. I don't have the "1283 PG 2.21 connectivity device" on my 4430sdp, but the earlier version of this patch was tested by Luciano Coelho. This version has left out the input logic for MMC CLK line compared to the earlier version as that is not bidirectional, and should be safe to do.

That caused the WLAN to stop working as the related .dts entries fell through the cracks. The legacy muxing was setting pulls for GPIO 48 and 49, so let's keep that behaviour for now to avoid further regressions for BT and FM. Also input logic was enabled for MMC CLK line, but I've verified that the input logic we don't need enabled for CLK line as it's not bidirectional. Also, we want to use non-removable instead of ti,non-removable as the ti,non-removable also sets no_regulator_off_init which is really not what we want as then wl12xx won't get powered up and down which is needed for resetting it. Note that looks like the WLAN interface fails to come up after a warm reset, but that most likely was also happening with the legacy booting and needs a separate fix.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a cpu goes to a deep idle state where its local timer is shutdown, it notifies the time frame work to use the broadcast timer instead. Unfortunately, the broadcast device could wake up any CPU, including an idle one which is not concerned by the wake up at all. This implies, in the worst case, an idle CPU will wake up to send an IPI to another idle cpu. This patch fixes this for ARM platforms using timer-sp, by setting CLOCK_EVT_FEAT_DYNIRQ feature.

| * | arch: mm: pass userspace fault flag to generic fault handlerJohannes Weiner2013-09-121-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unlike global OOM handling, memory cgroup code will invoke the OOM killer in any OOM situation because it has no way of telling faults occuring in kernel context - which could be handled more gracefully - from user-triggered faults. Pass a flag that identifies faults originating in user space from the architecture-specific fault handlers to generic code so that memcg OOM handling can be improved.

| * | arch: mm: do not invoke OOM killer on kernel fault OOMJohannes Weiner2013-09-121-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Kernel faults are expected to handle OOM conditions gracefully (gup, uaccess etc.), so they should never invoke the OOM killer. Reserve this for faults triggered in user context when it is the only option. Most architectures already do this, fix up the remaining few.

Also included are few small devicetree updates for sunxi, since it enables me to use one of their newer boards (cubieboard2) for additional test coverage. The support for that SoC is new for 3.12, so there's no exposure to new regressions due to it" * tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: ARM: dts: sun7i: olinuxino-micro: Enable the EMAC ARM: dts: sun7i: cubieboard2: Enable the EMAC ARM: dts: sun7i: Add the muxing options for the EMAC ARM: dts: sun7i: Enable the Ethernet in the A20 i2c: davinci: Fix bad dev_get_platdata() conversion ARM: vexpress: allow dcscb and tc2_pm in a combined ARMv6+v7 build ARM: shmobile: lager: Do not use register_type field of struct sh_eth_plat_data ARM: pxa: ssp: Check return values from phandle lookups ARM: PCI: versatile: Fix SMAP register offsets ARM: PCI: versatile: Fix PCI I/O ARM: PCI: versatile: Fix map_irq function to match hardware ARM: ep93xx: Don't use modem interface on the second UART ARM: shmobile: r8a7779: Update early timer initialisation order
