git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pin control updates from Linus Walleij: "This kernel cycle was quite calm when it comes to pin control and there is really just one major change, and that is the introduction of devm_pinctrl_register() managed resources. Apart from that linear development, details below. Core changes: - Add the devm_pinctrl_register() API and switch all applicable drivers to use it, saving lots of lines of code all over the place. New drivers: - driver for the Broadcom NS2 SoC - subdriver for the PXA25x SoCs - subdriver for the AMLogic Meson GXBB SoC Driver improvements: - the Intel Baytrail driver now properly supports pin control - Nomadik, Rockchip, Broadcom BCM2835 support the .get_direction() callback in the GPIO portions - continued development and stabilization of several SH-PFC SoC subdrivers: r8a7795, r8a7790, r8a7794 etc" * tag 'pinctrl-v4.7-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (85 commits) Revert "pinctrl: tegra: avoid parked_reg and parked_bank" pinctrl: meson: Fix eth_tx_en bit index pinctrl: tegra: avoid parked_reg and parked_bank pinctrl: tegra: Correctly check the supported configuration pinctrl: amlogic: Add support for Amlogic Meson GXBB SoC pinctrl: rockchip: fix pull setting error for rk3399 pinctrl: stm32: Implement .pin_config_dbg_show() pinctrl: nomadik: hide nmk_gpio_get_mode when unused pinctrl: ns2: rename pinctrl_utils_dt_free_map pinctrl: at91: Merge clk_prepare and clk_enable into clk_prepare_enable pinctrl: at91: Make at91_gpio_template const pinctrl: baytrail: fix some error handling in debugfs pinctrl: ns2: add pinmux driver support for Broadcom NS2 SoC pinctrl: sirf/atlas7: trivial fix of spelling mistake on flagged pinctrl: sh-pfc: Kill unused variable in sh_pfc_remove() pinctrl: nomadik: implement .get_direction() pinctrl: nomadik: use BIT() with offsets consequently pinctrl: exynos5440: Use off-stack memory for pinctrl_gpio_range pinctrl: zynq: Use devm_pinctrl_register() for pinctrl registration pinctrl: u300: Use devm_pinctrl_register() for pinctrl registration ...

The amount of changes in arch/arm for any of them is miniscule, as all the interesting code is in device driver subsystems (irqchip, clk, pinctrl, ...) these days. I'm listing them here, as the addition of the Kconfig statement is the main relevant milestone for a new platform. In each case, some drivers are are shared with existing platforms, while other drivers are added for v4.7 as well, or come in a later release. - The Aspeed platform is probably the most interesting one, this is what most whitebox servers use as their baseboard management controller. We get support for the very common ast2400 and ast2500 SoCs. The OpenBMC project focuses on this chip, and the LWN article about their ELC 2016 presentation at https://lwn.net/Articles/683320/ triggered the submission, but the code comes from IBM's OpenPOWER team rather than the team at Facebook. There are still a lot more drivers that need to get added over time, and I hope both teams can work together on that. - OXNAS is an old platform for Network Attached Storage devices from Oxford Semiconductor. There are models with ARM10 (!) and ARM11MPCore cores, but for now, we only support the original ARM9 based versions. The product lineup was subsequently part of PLX, Avago and now the new Broadcom Ltd. https://wiki.openwrt.org/doc/hardware/soc/soc.oxnas has some more information. - V2M-MPS2 is a prototyping platform from ARM for their Cortex-M cores and is related to the existing Realview / Versatile Express lineup, but without MMU. We now support various NOMMU platforms, so adding a new one is fairly straightforward. http://infocenter.arm.com/help/topic/com.arm.doc.100112_0100_03_en/ has detailed information about the platform. Other noteworthy updates: - Work on LPC32xx has resumed, and Vladimir Zapolskiy and Sylvain Lemieux are now maintaining the platform. This is an older ARM9 based platform from NXP (not Freescale), but it remains in use in embedded markets. - Kevin Hilman is now co-maintaining the Amlogic Meson platform for both 32-bit and 64-bit ARM, and started contributing some patches. - As is often the case, work on the OMAP platforms makes up the bulk of the actual SoC code changes in arch/arm, but there isn't a lot of that either" * tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (42 commits) MAINTAINERS: ARM/Amlogic: add co-maintainer, misc. updates MAINTAINERS: add ARM/NXP LPC32XX SoC specific drivers to the section MAINTAINERS: add new maintainers of NXP LPC32xx SoC MAINTAINERS: move ARM/NXP LPC32xx record to ARM section arm: Add Aspeed machine ARM: lpc32xx: remove duplicate const on lpc32xx_auxdata_lookup ARM: lpc32xx: remove leftovers of legacy clock source and provider drivers ARM: lpc32xx: remove reboot header file ARM: dove: Remove CLK_IS_ROOT ARM: orion5x: Remove CLK_IS_ROOT ARM: mv78xx0: Remove CLK_IS_ROOT ARM: davinci: da850: use clk->set_parent for async3 ARM: davinci: Move clock init after ioremap.

2016-05-18iwlwifi: fix mis-merge that breaks the driverLinus Torvalds1-1/+2
My laptop that uses the intel 7680 iwlwifi module would no longer connects to the network. It would fail with a "Microcode SW error detected." and spew out register state over and over again without ever connecting to the network. The cause is mis-merge in commit 909b27f70643, where David seems to have lost some of the changes to iwl_mvm_set_tx_cmd() from commit 5c08b0f5026f ("iwlwifi: mvm: don't override the rate with the AMSDU len"). The reason seems to be a conflict with commit d8fe484470dd ("iwlwifi: mvm: add support for new TX CMD API"), which touched a line adjacent to the changes in 909b27f70643. David missed the fact that "info->driver_data[0]" had become "skb_info->driver_data[0]". Then he removed the skb_info because it was unused. This just re-updates iwl_mvm_set_tx_cmd() with the lost two lines.

2016-05-18xfs: concurrent readdir hangs on data buffer locksDave Chinner1-9/+14
There's a three-process deadlock involving shared/exclusive barriers and inverted lock orders in the directory readdir implementation. It's a pre-existing problem with lock ordering, exposed by the VFS parallelisation code. process 1 process 2 process 3 --------- --------- --------- readdir iolock(shared) get_leaf_dents iterate entries ilock(shared) map, lock and read buffer iunlock(shared) process entries in buffer ..... readdir iolock(shared) get_leaf_dents iterate entries ilock(shared) map, lock buffer <blocks> finish ->iterate_shared file_accessed() ->update_time start transaction ilock(excl) <blocks> ..... finishes processing buffer get next buffer ilock(shared) <blocks> And that's the deadlock. Fix this by dropping the current buffer lock in process 1 before trying to map the next buffer. This means we keep the lock order of ilock -> buffer lock intact and hence will allow process 3 to make progress and drop it's ilock(shared) once it is done.

2016-05-18KVM: MTRR: remove MSR 0x2f8Andy Honig1-2/+0
MSR 0x2f8 accessed the 124th Variable Range MTRR ever since MTRR support was introduced by 9ba075a664df ("KVM: MTRR support"). 0x2f8 became harmful when 910a6aae4e2e ("KVM: MTRR: exactly define the size of variable MTRRs") shrinked the array of VR MTRRs from 256 to 8, which made access to index 124 out of bounds. The surrounding code only WARNs in this situation, thus the guest gained a limited read/write access to struct kvm_arch_vcpu. 0x2f8 is not a valid VR MTRR MSR, because KVM has/advertises only 16 VR MTRR MSRs, 0x200-0x20f. Every VR MTRR is set up using two MSRs, 0x2f8 was treated as a PHYSBASE and 0x2f9 would be its PHYSMASK, but 0x2f9 was not implemented in KVM, therefore 0x2f8 could never do anything useful and getting rid of it is safe.

2016-05-18KVM: x86: make hwapic_isr_update and hwapic_irr_update look the samePaolo Bonzini4-10/+10
Neither APICv nor AVIC actually need the first argument of hwapic_isr_update, but the vCPU makes more sense than passing the pointer to the whole virtual machine! In fact in the APICv case it's just happening that the vCPU is used implicitly, through the loaded VMCS. The second argument instead is named differently, make it consistent.

2016-05-18svm: Manage vcpu load/unload when enable AVICSuravee Suthikulpanit1-0/+89
When a vcpu is loaded/unloaded to a physical core, we need to update host physical APIC ID information in the Physical APIC-ID table accordingly. Also, when vCPU is blocking/un-blocking (due to halt instruction), we need to make sure that the is-running bit in set accordingly in the physical APIC-ID table.

2016-05-18svm: Add interrupt injection via AVICSuravee Suthikulpanit1-4/+35
This patch introduces a new mechanism to inject interrupt using AVIC. Since VINTR is not supported when enable AVIC, we need to inject interrupt via APIC backing page instead. This patch also adds support for AVIC doorbell, which is used by KVM to signal a running vcpu to check IRR for injected interrupts.

2016-05-18KVM: x86: Detect and Initialize AVIC supportSuravee Suthikulpanit3-1/+231
This patch introduces AVIC-related data structure, and AVIC initialization code. There are three main data structures for AVIC: * Virtual APIC (vAPIC) backing page (per-VCPU) * Physical APIC ID table (per-VM) * Logical APIC ID table (per-VM) Currently, AVIC is disabled by default. Users can manually enable AVIC via kernel boot option kvm-amd.avic=1 or during kvm-amd module loading with parameter avic=1.

2016-05-18KVM: shrink halt polling even more for invalid wakeupsChristian Borntraeger1-3/+4
commit 3491caf2755e ("KVM: halt_polling: provide a way to qualify wakeups during poll") added more aggressive shrinking of the polling interval if the wakeup did not match some criteria. This still allows to keep polling enabled if the polling time was smaller that the current max poll time (block_ns <= vcpu->halt_poll_ns). Performance measurement shows that even more aggressive shrinking (shrink polling on any invalid wakeup) reduces absolute and relative (to the workload) CPU usage even further.

2016-05-18arc: axs103_smp: Fix CPU frequency to 100MHz for dual-coreAlexey Brodkin2-3/+1
The most recent release of AXS103 [v1.1] is proven to work at 100 MHz in dual-core mode so this change uses mentioned feature. For that we: * Update axc003_idu.dtsi with mention of really-used CPU clock freq * Remove clock override in AXS platform code for dual-core HW Note we're still leaving a hack for clock "downgrade" on early boot for quad-core hardware. Also note this change will break functionality of AXS103 v1.0 hardware. That means all users of AXS103 __must__ upgrade their boards with the most recent firmware.
