git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull driver core updates from Greg KH: "Here's the new driver core patches for 4.10-rc1. Big thing here is the nice addition of "functional dependencies" to the driver core. The idea has been talked about for a very long time, great job to Rafael for stepping up and implementing it. It's been tested for longer than the 4.9-rc1 date, we held off on merging it earlier in order to feel more comfortable about it. Other than that, it's just a handful of small other patches, some good cleanups to the mess that is the firmware class code, and we have a test driver for the deferred probe logic.

Not as big as 4.9 was, but still just over a thousand changes.

2016-12-13Merge branch 'for-4.10/block' of git://git.kernel.dk/linux-blockLinus Torvalds5-20/+85
Pull block layer updates from Jens Axboe: "This is the main block pull request this series. Contrary to previous release, I've kept the core and driver changes in the same branch. We always ended up having dependencies between the two for obvious reasons, so makes more sense to keep them together. That said, I'll probably try and keep more topical branches going forward, especially for cycles that end up being as busy as this one. The major parts of this pull request is: - Improved support for O_DIRECT on block devices, with a small private implementation instead of using the pig that is fs/direct-io.c. From Christoph. - Request completion tracking in a scalable fashion. This is utilized by two components in this pull, the new hybrid polling and the writeback queue throttling code. - Improved support for polling with O_DIRECT, adding a hybrid mode that combines pure polling with an initial sleep. From me. - Support for automatic throttling of writeback queues on the block side. This uses feedback from the device completion latencies to scale the queue on the block side up or down. From me. - Support from SMR drives in the block layer and for SD. From Hannes and Shaun. - Multi-connection support for nbd. From Josef. - Cleanup of request and bio flags, so we have a clear split between which are bio (or rq) private, and which ones are shared. From Christoph. - A set of patches from Bart, that improve how we handle queue stopping and starting in blk-mq. - Support for WRITE_ZEROES from Chaitanya. - Lightnvm updates from Javier/Matias. - Supoort for FC for the nvme-over-fabrics code.

Pull VFIO updates from Alex Williamson: - VFIO updates for v4.10 primarily include a new Mediated Device interface, which essentially allows software defined devices to be exposed to users through VFIO. The host vendor driver providing this virtual device polices, or mediates user access to the device. These devices often incorporate portions of real devices, for instance the primary initial users of this interface expose vGPUs which allow the user to map mediated devices, or mdevs, to a portion of a physical GPU. QEMU composes these mdevs into PCI representations using the existing VFIO user API. This enables both Intel KVM-GT support, which is also expected to arrive into Linux mainline during the v4.10 merge window, as well as NVIDIA vGPU, and also Channel I/O devices (aka CCW devices) for s390 virtualization support.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "This is a fairly quiet release. We don't have any patches to the core framework. The only patch that can even be considered "core" adds another clk_get() variant. The rest of the changes are in drivers for various SoCs, and we have a few bits for ARM shmobile architecture code (dts and mach) due to the dependency we're breaking between shmobile architecture code and its clk driver. Those shmobile bits have also been pulled into arm-soc tree.

Pull remoteproc updates from Bjorn Andersson: - introduce remoteproc "subdevice" support, which allows remoteproc driver to associate devices to the "running" state of the remoteproc, allowing devices to be probed and removed as the remote processor is booted, shut down or recovering from a crash. - handling of virtio device resources was improved, vring memory is now allocated as part of other memory allocation. This ensures that all vrings for all virtio devices are allocated before we boot the remote processor. - the debugfs mechanism for starting and stopping remoteproc instances was replaced with a sysfs interface, also providing a mechanism for specifying firmware to use by the instance. This allows user space to load and boot use case specific firmware on remote processors. - new drivers for the ST Slimcore and Qualcomm Hexagon DSP as well as removal of the unused StE modem loader. - finally support for crash recovery in the Qualcomm Wirelss subsystem (used for WiFi/BT/FM on a number of platforms) and a number of bug fixes and cleanups * tag 'rproc-v4.10' of git://github.com/andersson/remoteproc: (49 commits) remoteproc: qcom_adsp_pil: select qcom_scm remoteproc: Drop wait in __rproc_boot() remoteproc/ste: Delete unused driver remoteproc: Remove "experimental" warning remoteproc: qcom_adsp_pil: select qcom_scm dt-binding: soc: qcom: smd: Add label property remoteproc: qcom: mdt_loader: add include for sizes remoteproc: Update last rproc_put users to rproc_free remoteproc: qcom: adsp: Add missing MODULE_DEVICE_TABLE remoteproc: wcnss-pil: add QCOM_SMD dependency dmaengine: st_fdma: Revert: "Revert: Update st_fdma to 'depends on REMOTEPROC'" remoteproc: Add support for xo clock remoteproc: adsp-pil: fix recursive dependency remoteproc: Introduce Qualcomm ADSP PIL dt-binding: remoteproc: Introduce ADSP loader binding remoteproc: qcom_wcnss: Fix circular module dependency remoteproc: Merge table_ptr and cached_table pointers remoteproc: Remove custom vdev handler list remoteproc: Update max_notifyid as we allocate vrings remoteproc: Decouple vdev resources and devices ...

2016-12-12mm: make transparent hugepage size publicHugh Dickins1-0/+5
Test programs want to know the size of a transparent hugepage. While it is commonly the same as the size of a hugetlbfs page (shown as Hugepagesize in /proc/meminfo), that is not always so: powerpc implements transparent hugepages in a different way from hugetlbfs pages, so it's coincidence when their sizes are the same; and x86 and others can support more than one hugetlbfs page size. Add /sys/kernel/mm/transparent_hugepage/hpage_pmd_size to show the THP size in bytes - it's the same for Anonymous and Shmem hugepages. Call it hpage_pmd_size (after HPAGE_PMD_SIZE) rather than hpage_size, in case some transparent support for pud and pgd pages is added later.

2016-12-12mm: remove x86-only restriction of movable_nodeReza Arbab1-1/+1
In commit c5320926e370 ("mem-hotplug: introduce movable_node boot option"), the memblock allocation direction is changed to bottom-up and then back to top-down like this: 1. memblock_set_bottom_up(true), called by cmdline_parse_movable_node(). 2. memblock_set_bottom_up(false), called by x86's numa_init(). Even though (1) occurs in generic mm code, it is wrapped by #ifdef CONFIG_MOVABLE_NODE, which depends on X86_64. This means that when we extend CONFIG_MOVABLE_NODE to non-x86 arches, things will be unbalanced. (1) will happen for them, but (2) will not. This toggle was added in the first place because x86 has a delay between adding memblocks and marking them as hotpluggable. Since other arches do this marking either immediately or not at all, they do not require the bottom-up toggle. So, resolve things by moving (1) from cmdline_parse_movable_node() to x86's setup_arch(), immediately after the movable_node parameter has been parsed.
