Pull intel iommu updates from David Woodhouse: "This lays a little of the groundwork for upcoming Shared Virtual Memory support — fixing some bogus #defines for capability bits and adding the new ones, and starting to use the new wider page tables where we can, in anticipation of actually filling in the new fields therein. It also allows graphics devices to be assigned to VM guests again. This got broken in 3.17 by disallowing assignment of RMRR-afflicted devices. Like USB, we do understand why there's an RMRR for graphics devices — and unlike USB, it's actually sane. So we can make an exception for graphics devices, just as we do USB controllers. Finally, tone down the warning about the X2APIC_OPT_OUT bit, due to persistent requests. X2APIC_OPT_OUT was added to the spec as a nasty hack to allow broken BIOSes to forbid us from using X2APIC when they do stupid and invasive things and would break if we did. Someone noticed that since Windows doesn't have full IOMMU support for DMA protection, setting the X2APIC_OPT_OUT bit made Windows avoid initialising the IOMMU on the graphics unit altogether. This means that it would be available for use in "driver mode", where the IOMMU registers are made available through a BAR of the graphics device and the graphics driver can do SVM all for itself. So they started setting the X2APIC_OPT_OUT bit on *all* platforms with SVM capabilities. And even the platforms which *might*, if the planets had been aligned correctly, possibly have had SVM capability but which in practice actually don't" * git://git.infradead.org/intel-iommu: iommu/vt-d: support extended root and context entries iommu/vt-d: Add new extended capabilities from v2.3 VT-d specification iommu/vt-d: Allow RMRR on graphics devices too iommu/vt-d: Print x2apic opt out info instead of printing a warning iommu/vt-d: kill bogus ecap_niotlb_iunits()

2015-04-24platform/chrome: chromeos_laptop - instantiate Atmel at primary addressDmitry Torokhov
The new Atmel MXT driver expects i2c client's address contain the primary (main address) of the chip, and calculates the expected bootloader address form the primary address. Unfortunately chrome_laptop does probe the devices and if touchpad (or touchscreen, or both) comes up in bootloader mode the i2c device gets instantiated with the bootloader address which confuses the driver. To work around this issue let's probe the primary address first. If the device is not detected at the primary address we'll probe alternative addresses as "dummy" devices. If any of them are found, destroy the dummy client and instantiate client with proper name at primary address still.

2015-04-24toshiba_acpi: Do not register vendor backlight when acpi_video bl is availableHans de Goede
commit a39f46df33c6 ("toshiba_acpi: Fix regression caused by backlight extra check code") causes the backlight to no longer work on the Toshiba Z30, reverting that commit fixes this but restores the original issue fixed by that commit. Looking at the toshiba_acpi backlight code for a fix for this I noticed that the toshiba code is the only code under platform/x86 which unconditionally registers a vendor acpi backlight interface, without checking for acpi_video backlight support first. This commit adds the necessary checks bringing toshiba_acpi in line with the other drivers, and fixing the Z30 regression without needing to revert the commit causing it. Chances are that there will be some Toshiba models which have a non working acpi-video implementation while the toshiba vendor backlight interface does work, this commit adds an empty dmi_id table where such systems can be added, this is identical to how other drivers handle such systems.

Pull md updates from Neil Brown: "More updates that usual this time. A few have performance impacts which hould mostly be positive, but RAID5 (in particular) can be very work-load ensitive... We'll have to wait and see. Highlights: - "experimental" code for managing md/raid1 across a cluster using DLM. Code is not ready for general use and triggers a WARNING if used. However it is looking good and mostly done and having in mainline will help co-ordinate development. - RAID5/6 can now batch multiple (4K wide) stripe_heads so as to handle a full (chunk wide) stripe as a single unit. - RAID6 can now perform read-modify-write cycles which should help performance on larger arrays: 6 or more devices. - RAID5/6 stripe cache now grows and shrinks dynamically. The value set is used as a minimum. - Resync is now allowed to go a little faster than the 'mininum' when there is competing IO. How much faster depends on the speed of the devices, so the effective minimum should scale with device speed to some extent" * tag 'md/4.1' of git://neil.brown.name/md: (58 commits) md/raid5: don't do chunk aligned read on degraded array. md/raid5: allow the stripe_cache to grow and shrink. md/raid5: change ->inactive_blocked to a bit-flag. md/raid5: move max_nr_stripes management into grow_one_stripe and drop_one_stripe md/raid5: pass gfp_t arg to grow_one_stripe() md/raid5: introduce configuration option rmw_level md/raid5: activate raid6 rmw feature md/raid6 algorithms: xor_syndrome() for SSE2 md/raid6 algorithms: xor_syndrome() for generic int md/raid6 algorithms: improve test program md/raid6 algorithms: delta syndrome functions raid5: handle expansion/resync case with stripe batching raid5: handle io error of batch list RAID5: batch adjacent full stripe write raid5: track overwrite disk count raid5: add a new flag to track if a stripe can be batched raid5: use flex_array for scribble data md raid0: access mddev->queue (request queue member) conditionally because it is not set when accessed from dm-raid md: allow resync to go faster when there is competing IO. md: remove 'go_faster' option from ->sync_request() ...

git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull initial ACPI support for arm64 from Will Deacon: "This series introduces preliminary ACPI 5.1 support to the arm64 kernel using the "hardware reduced" profile. We don't support any peripherals yet, so it's fairly limited in scope: - MEMORY init (UEFI) - ACPI discovery (RSDP via UEFI) - CPU init (FADT) - GIC init (MADT) - SMP boot (MADT + PSCI) - ACPI Kconfig options (dependent on EXPERT) ACPI for arm64 has been in development for a while now and hardware has been available that can boot with either FDT or ACPI tables. This has been made possible by both changes to the ACPI spec to cater for ARM-based machines (known as "hardware-reduced" in ACPI parlance) but also a Linaro-driven effort to get this supported on top of the Linux kernel. This pull request is the result of that work. These changes allow us to initialise the CPUs, interrupt controller, and timers via ACPI tables, with memory information and cmdline coming from EFI. We don't support a hybrid ACPI/FDT scheme. Of course, there is still plenty of work to do (a serial console would be nice!) but I expect that to happen on a per-driver basis after this core series has been merged. Anyway, the diff stat here is fairly horrible, but splitting this up and merging it via all the different subsystems would have been extremely painful. Instead, we've got all the relevant Acks in place and I've not seen anything other than trivial (Kconfig) conflicts in -next (for completeness, I've included my resolution below). Nearly half of the insertions fall under Documentation/. So, we'll see how this goes. Right now, it all depends on EXPERT and I fully expect people to use FDT by default for the immediate future" * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (31 commits) ARM64 / ACPI: make acpi_map_gic_cpu_interface() as void function ARM64 / ACPI: Ignore the return error value of acpi_map_gic_cpu_interface() ARM64 / ACPI: fix usage of acpi_map_gic_cpu_interface ARM64: kernel: acpi: honour acpi=force command line parameter ARM64: kernel: acpi: refactor ACPI tables init and checks ARM64: kernel: psci: let ACPI probe PSCI version ARM64: kernel: psci: factor out probe function ACPI: move arm64 GSI IRQ model to generic GSI IRQ layer ARM64 / ACPI: Don't unflatten device tree if acpi=force is passed ARM64 / ACPI: additions of ACPI documentation for arm64 Documentation: ACPI for ARM64 ARM64 / ACPI: Enable ARM64 in Kconfig XEN / ACPI: Make XEN ACPI depend on X86 ARM64 / ACPI: Select ACPI_REDUCED_HARDWARE_ONLY if ACPI is enabled on ARM64 clocksource / arch_timer: Parse GTDT to initialize arch timer irqchip: Add GICv2 specific ACPI boot support ARM64 / ACPI: Introduce ACPI_IRQ_MODEL_GIC and register device's gsi ACPI / processor: Make it possible to get CPU hardware ID via GICC ACPI / processor: Introduce phys_cpuid_t for CPU hardware ID ARM64 / ACPI: Parse MADT for SMP initialization ...

2015-04-24ACPI / scan: Add a scan handler for PRP0001Rafael J. Wysocki
If the special PRP0001 device ID is present in the given device's list of ACPI/PNP IDs and the device has a valid "compatible" property in the _DSD, it should be enumerated using the default mechanism, unless some scan handlers match the IDs preceding PRP0001 in the device's list of ACPI/PNP IDs. In addition to that, no scan handlers matching the IDs following PRP0001 in that list should be attached to the device. To make that happen, define a scan handler that will match PRP0001 and trigger the default enumeration for the matching devices if the "compatible" property is present for them. Since that requires the check for platform_id and device->handler to be removed from acpi_default_enumeration(), move the fallback invocation of acpi_default_enumeration() to acpi_bus_attach() (after it's checked if there's a matching ACPI driver for the device), which is a better place to call it, and do the platform_id check in there too (device->handler is guaranteed to be unset at the point where the function is looking for a matching ACPI driver).
