Pull ARM SoC fixes from Arnd Bergmann: "There is a small backlog of at91 patches here, the most significant is the addition of some sama5d2 Xplained nodes that were waiting on an MFD include file to get merged through another tree. We normally try to sort those out before the merge window opens, but the maintainer wasn't aware of that here and I decided to merge the changes this time as an exception. On OMAP a series of audio changes for dra7 missed the merge window but turned out to be necessary to fix a boot time imprecise external abort error and to get audio working. The other changes are the usual simple changes, here is a list sorted by platform: at91: removal of a useless defconfig option removal of some legacy DT pieces use of the proper watchdog compatible string update of the MAINTAINERS entries for some Atmel drivers drivers/scpi: hide get_scpi_ops in module from built-in code imx: add missing .irq_set_type for i.MX GPC irq_chip. fix the wrong spi-num-chipselects settings for Vybrid DSPI devices. fix a merge error in Vybrid dts regarding to ADC device property keystone: fix the optional PDSP firmware loading fix linking RAM setup for QMs fix crash with clk_ignore_unused mediatek: Enable SCPSYS power domain driver by default mvebu: fix QNAP TS219 power-off in dts fix legacy get_irqnr_and_base for dove and orion5x omap: fix l4 related boot time errors for dm81xx use lockless cldm/pwrdm api in omap4_boot_secondary remove t410 abort handler to avoid hiding other critical errors mark cpuidle tracepoints as _rcuidle fix module alias for omap-ocp2scp pxa: palm: Fix typos in PWM lookup table code renesas: missing __initconst annotation for r8a7793_boards_compat_dt rockchip: disable mmc-tuning on the veyron-minnie board adding the init state for the over-temperature-protection zx: only build power domain code when CONFIG_PM=y" * tag 'fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (31 commits) ARM: OMAP4+: SMP: use lockless clkdm/pwrdm api in omap4_boot_secondary arm: omap2+: add missing HWMOD_NO_IDLEST in 81xx hwmod data ARM: orion5x: Fix legacy get_irqnr_and_base ARM: dove: Fix legacy get_irqnr_and_base soc: Mediatek: Enable SCPSYS power domain driver by default ARM: dts: vfxxx: Fix dspi[01] spi-num-chipselects.

Pull block layer fixes from Jens Axboe: "A round of fixes/updates for the current series. This looks a little bigger than it is, but that's mainly because we pushed the lightnvm enabled null_blk change out of the merge window so it could be updated a bit. The rest of the volume is also mostly lightnvm. In particular: - Lightnvm. Various fixes, additions, updates from Matias and Javier, as well as from Wenwei Tao. - NVMe: - Fix for potential arithmetic overflow from Keith. - Also from Keith, ensure that we reap pending completions from a completion queue before deleting it. Fixes kernel crashes when resetting a device with IO pending. - Various little lightnvm related tweaks from Matias. - Fixup flushes to go through the IO scheduler, for the cases where a flush is not required. Fixes a case in CFQ where we would be idling and not see this request, hence not break the idling. From Jan Kara. - Use list_{first,prev,next} in elevator.c for cleaner code. From Gelian Tang. - Fix for a warning trigger on btrfs and raid on single queue blk-mq devices, where we would flush plug callbacks with preemption disabled. From me. - A mac partition validation fix from Kees Cook. - Two merge fixes from Ming, marked stable. A third part is adding a new warning so we'll notice this quicker in the future, if we screw up the accounting. - Cleanup of thread name/creation in mtip32xx from Rasmus Villemoes" * 'for-linus' of git://git.kernel.dk/linux-block: (32 commits) blk-merge: warn if figured out segment number is bigger than nr_phys_segments blk-merge: fix blk_bio_segment_split block: fix segment split blk-mq: fix calling unplug callbacks with preempt disabled mac: validate mac_partition is within sector mtip32xx: use formatting capability of kthread_create_on_node NVMe: reap completion entries when deleting queue lightnvm: add free and bad lun info to show luns lightnvm: keep track of block counts nvme: lightnvm: use admin queues for admin cmds lightnvm: missing free on init error lightnvm: wrong return value and redundant free null_blk: do not del gendisk with lightnvm null_blk: use device addressing mode null_blk: use ppa_cache pool NVMe: Fix possible arithmetic overflow for max segments blk-flush: Queue through IO scheduler when flush not required null_blk: register as a LightNVM device elevator: use list_{first,prev,next}_entry lightnvm: cleanup queue before target removal ...

ARM: dts: keystone: k2l: fix kernel crash when clk_ignore_unused is not in bootargs

2015-11-23T18:36:27Z

Currently kernel crash randomly when K2L EVM is booted without clk_ignore_unused in the bootargs. This workaround is not needed on other K2 devices such as K2HK and K2E and with this fix, we can remove the workaround altogether. netcp driver on K2L uses linked ram on OSR (On chip Static RAM) and requires the clock to this peripheral enabled for proper functioning. This is the reason for the kernel crash. So add the clock node to fix this issue. While at it, remove the workaround documentation as well. With the fix applied, clk_summary dump shows the clock to OSR enabled. cat /sys/kernel/debug/clk/clk_summary ------cut-------------- tcp3d-1 0 0 399360000 0 0 tcp3d-0 0 0 399360000 0 0 osr 1 1 399360000 0 0 fftc-0 0 0 399360000 0 0 -----cut---------------- Signed-off-by: Murali Karicheri Signed-off-by: Santosh Shilimkar

Pull more power management and ACPI updates from Rafael Wysocki: "These are mostly fixes and cleanups (ACPI core, PM core, cpufreq, ACPI EC driver, device properties) including three reverts of recent intel_pstate driver commits due to a regression introduced by one of them plus support for Atom Airmont cores in intel_pstate (which really boils down to adding new frequency tables for Airmont) and additional turbostat updates. Specifics: - Revert three recent intel_pstate driver commits one of which introduced a regression and the remaining two depend on the problematic one (Rafael Wysocki). - Fix breakage related to the recently introduced ACPI _CCA object support in the PCI DMA setup code (Suravee Suthikulpanit). - Fix up the recently introduced ACPI CPPC support to only use the hardware-reduced version of the PCCT structure as the only architecture to support it (ARM64) will only use hardware-reduced ACPI anyway (Ashwin Chaugule). - Fix a cpufreq mediatek driver build problem (Arnd Bergmann). - Fix the SMBus transaction handling implementation in the ACPI core to avoid re-entrant calls to wait_event_timeout() which makes intermittent boot stalls related to the Smart Battery Subsystem initialization go away and revert a workaround of another problem with the same underlying root cause (Chris Bainbridge). - Fix the generic wakeup interrupts framework to avoid using invalid IRQ numbers (Dmitry Torokhov). - Remove a redundant check from the ACPI EC driver (Markus Elfring). - Modify the intel_pstate driver so it can support more Atom flavors than just one (Baytrail) and add support for Atom Airmont cores (which require new freqnency tables) to it (Philippe Longepe). - Clean up MSR-related symbols in turbostat (Len Brown)" * tag 'pm+acpi-4.4-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: PCI: Fix OF logic in pci_dma_configure() Revert "Documentation: kernel_parameters for Intel P state driver" cpufreq: mediatek: fix build error cpufreq: intel_pstate: Add separate support for Airmont cores cpufreq: intel_pstate: Replace BYT with ATOM Revert "cpufreq: intel_pstate: Use ACPI perf configuration" Revert "cpufreq: intel_pstate: Avoid calculation for max/min" ACPI-EC: Drop unnecessary check made before calling acpi_ec_delete_query() Revert "ACPI / SBS: Add 5 us delay to fix SBS hangs on MacBook" ACPI / SMBus: Fix boot stalls / high CPU caused by reentrant code PM / wakeirq: check that wake IRQ is valid before accepting it ACPI / CPPC: Use h/w reduced version of the PCCT structure x86: remove unused definition of MSR_NHM_PLATFORM_INFO tools/power turbostat: use new name for MSR_PLATFORM_INFO

null_blk: register as a LightNVM device

2015-11-16T22:22:28Z

Add support for registering as a LightNVM device. This allows us to evaluate the performance of the LightNVM subsystem. In /drivers/Makefile, LightNVM is moved above block device drivers to make sure that the LightNVM media managers have been initialized before drivers under /drivers/block are initialized.
