2014-01-25iscsi-target: Convert gfp_t parameter to task state bitmaskNicholas Bellinger
This patch propigates the use of task state bitmask now used by percpu_ida_alloc() up the iscsi-target callchain, replacing the use of GFP_ATOMIC for TASK_RUNNING, and GFP_KERNEL for TASK_INTERRUPTIBLE. Also, drop the unnecessary gfp_t parameter to isert_allocate_cmd(), and just pass TASK_INTERRUPTIBLE into iscsit_allocate_cmd(). Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
2014-01-25iscsi-target: Fix connection reset hang with percpu_ida_allocNicholas Bellinger
This patch addresses a bug where connection reset would hang indefinately once percpu_ida_alloc() was starved for tags, due to the fact that it always assumed uninterruptible sleep mode. So now make percpu_ida_alloc() check for signal_pending_state() for making interruptible sleep optional, and convert iscsit_allocate_cmd() to set TASK_INTERRUPTIBLE for GFP_KERNEL, or TASK_RUNNING for GFP_ATOMIC.

git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux Pull thermal management updates from Zhang Rui: "This time, the biggest change is the work of representing hardware thermal properties in device tree infrastructure. This work includes the introduction of a device tree bindings for describing the hardware thermal behavior and limits, and also a parser to read and interpret the data, and build thermal zones and thermal binding parameters. It also contains three examples on how to use the new representation on sensor devices, using three different drivers to accomplish it. One driver is in thermal subsystem, the TI SoC thermal, and the other two drivers are in hwmon subsystem. Actually, this would be the first step of the complete work because we still need to check other potential drivers to be converted and then validate the proposed API. But the reason why I include it in this pull request is that, first, this change does not hurt any others without using this approach, second, the principle and concept of this change would not break after converting the remaining drivers. BTW, as you can see, there are several points in this change that do not belong to thermal subsystem. Because it has been suggested by Guenter R that in such cases, it is recommended to send the complete series via one single subsystem. Specifics: - representing hardware thermal properties in device tree infrastructure - fix a regression that the imx thermal driver breaks system suspend. - introduce ACPI INT3403 thermal driver to retrieve temperature data from the INT3403 ACPI device object present on some systems. - introduce debug statement for thermal core and step_wise governor. - assorted fixes and cleanups for thermal core, cpu cooling, exynos thrmal, intel powerclamp and imx thermal driver" * 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux: (34 commits) thermal: remove const flag from .ops of imx thermal Thermal: update thermal zone device after setting emul_temp intel_powerclamp: Fix cstate counter detection. thermal: imx: add necessary clk operation Thermal cpu cooling: return error if no valid cpu frequency entry thermal: fix cpu_cooling max_level behavior thermal: rcar-thermal: Enable driver compilation with COMPILE_TEST thermal: debug: add debug statement for core and step_wise thermal: imx_thermal: add module device table drivers: thermal: Mark function as static in x86_pkg_temp_thermal.c thermal:samsung: fix compilation warning thermal: imx: correct suspend/resume flow thermal: exynos: fix error return code Thermal: ACPI INT3403 thermal driver MAINTAINERS: add thermal bindings entry in thermal domain arm: dts: make OMAP4460 bandgap node to belong to OCP arm: dts: make OMAP443x bandgap node to belong to OCP arm: dts: add cooling properties on omap5 cpu node arm: dts: add omap5 thermal data arm: dts: add omap5 CORE thermal data ...

2014-01-24ipv6: reallocate addrconf router for ipv6 address when lo device upGao feng
commit 25fb6ca4ed9cad72f14f61629b68dc03c0d9713f "net IPv6 : Fix broken IPv6 routing table after loopback down-up" allocates addrconf router for ipv6 address when lo device up. but commit a881ae1f625c599b460cc8f8a7fcb1c438f699ad "ipv6:don't call addrconf_dst_alloc again when enable lo" breaks this behavior. Since the addrconf router is moved to the garbage list when lo device down, we should release this router and rellocate a new one for ipv6 address when lo device up.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull ACPI and power management updates from Rafael Wysocki: "As far as the number of commits goes, the top spot belongs to ACPI this time with cpufreq in the second position and a handful of PM core, PNP and cpuidle updates. They are fixes and cleanups mostly, as usual, with a couple of new features in the mix. The most visible change is probably that we will create struct acpi_device objects (visible in sysfs) for all devices represented in the ACPI tables regardless of their status and there will be a new sysfs attribute under those objects allowing user space to check that status via _STA. Consequently, ACPI device eject or generally hot-removal will not delete those objects, unless the table containing the corresponding namespace nodes is unloaded, which is extremely rare. Also ACPI container hotplug will be handled quite a bit differently and cpufreq will support CPU boost ("turbo") generically and not only in the acpi-cpufreq driver. Specifics: - ACPI core changes to make it create a struct acpi_device object for every device represented in the ACPI tables during all namespace scans regardless of the current status of that device. In accordance with this, ACPI hotplug operations will not delete those objects, unless the underlying ACPI tables go away. - On top of the above, new sysfs attribute for ACPI device objects allowing user space to check device status by triggering the execution of _STA for its ACPI object. From Srinivas Pandruvada. - ACPI core hotplug changes reducing code duplication, integrating the PCI root hotplug with the core and reworking container hotplug. - ACPI core simplifications making it use ACPI_COMPANION() in the code "glueing" ACPI device objects to "physical" devices. - ACPICA update to upstream version 20131218. This adds support for the DBG2 and PCCT tables to ACPICA, fixes some bugs and improves debug facilities. From Bob Moore, Lv Zheng and Betty Dall. - Init code change to carry out the early ACPI initialization earlier. That should allow us to use ACPI during the timekeeping initialization and possibly to simplify the EFI initialization too. From Chun-Yi Lee. - Clenups of the inclusions of ACPI headers in many places all over from Lv Zheng and Rashika Kheria (work in progress). - New helper for ACPI _DSM execution and rework of the code in drivers that uses _DSM to execute it via the new helper.

2014-01-24MIPS: KVM: remove shadow_tlb codeJames Hogan
The kvm_mips_init_shadow_tlb() function is called from kvm_arch_vcpu_init() and initialises entries 0 to current_cpu_data.tlbsize-1 of the virtual cpu's shadow_tlb[64] array. However newer cores with FTLBs can have a tlbsize > 64, for example the ProAptiv I'm testing on has a total tlbsize of 576. This causes kvm_mips_init_shadow_tlb() to overflow the shadow_tlb[64] array and overwrite the comparecount_timer among other things, causing a lock up when starting a KVM guest. Aside from kvm_mips_init_shadow_tlb() which only initialises it, the shadow_tlb[64] array is only actually used by the following functions: - kvm_shadow_tlb_put() & kvm_shadow_tlb_load() These are never called. The only call sites are #if 0'd out. - kvm_mips_dump_shadow_tlbs() This is never called. It was originally added for trap & emulate, but turned out to be unnecessary so it was disabled. So instead of fixing the shadow_tlb initialisation code, lets just remove the shadow_tlb[64] array and the above functions entirely. The only functional change here is the removal of broken shadow_tlb initialisation. The rest just deletes dead code.

2014-01-24MIPS: KVM: use common EHINV aware UNIQUE_ENTRYHIJames Hogan
When KVM is enabled and TLB invalidation is supported, kvm_mips_flush_host_tlb() can cause a machine check exception due to multiple matching TLB entries. This can occur on shutdown even when KVM hasn't been actively used. Commit adb78de9eae8 (MIPS: mm: Move UNIQUE_ENTRYHI macro to a header file) created a common UNIQUE_ENTRYHI in asm/tlb.h but it didn't update the copy of UNIQUE_ENTRYHI in kvm_tlb.c to use it. Commit 36b175451399 (MIPS: tlb: Set the EHINV bit for TLBINVF cores when invalidating the TLB) later added TLB invalidation (EHINV) support to the common UNIQUE_ENTRYHI. Therefore make kvm_tlb.c use the EHINV aware UNIQUE_ENTRYHI implementation in asm/tlb.h too.

2014-01-24bcma: prevent irq handler from firing when registeredHauke Mehrtens
With this patch we prevent the irq from being fired when it is registered. The Hardware fires an IRQ when input signal XOR polarity AND gpio mask is 1. Now we are setting polarity to a vlaue so that is is 0 when we register it. In addition we also set the irq mask register to 0 when the irq handler is initialized, so all gpio irqs are masked and there will be no unexpected irq.

2014-01-24MIPS: bcm63xx: cpu: Replace BUG() with panic()Markos Chandras
BUG() can be a noop if CONFIG_BUG is not selected, leading to the following build problem on a randconfig: arch/mips/bcm63xx/cpu.c: In function 'detect_cpu_clock': arch/mips/bcm63xx/cpu.c:254:1: error: control reaches end of non-void function [-Werror=return-type] We fix this problem by replacing BUG() with panic() since it's best to handle the case of an unknown board instead of silently returning a random clock frequency.

This old wgt634u.c was trying to implement a bit ugly support for Netgear WGT634U. It provided info about LED, flash mapping & layout and was trying to handle reset button.

So far this adds support for one Netgear model only, but it's designed and ready to add many more device. We could hopefully import database from OpenWrt.

2014-01-24MIPS: BCM47XX: Prepare support for LEDsRafał Miłecki
So far this is mostly just a proof of concept, database consists of a single device. Creating a nice iterateable array wasn't an option because devices have different amount of LEDs. And we don't want to waste memory just because of support for a device with dozens on LEDs.

2014-01-24MIPS: BCM47XX: do not use cpu_wait instruction on BCM4706Hauke Mehrtens
The BCM4706 has a problem with the CPU wait instruction. When r4k_wait or r4k_wait_irqoff is used will just hang and not return from a msleep(). Removing the cpu_wait functionality is a workaround for this problem. The BCM4716 does not have this problem. The BCM4706 SoC uses a MIPS 74K V4.9 CPU.
