git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace Pull namespace updates from Eric Biederman: "After a lot of discussion and work we have finally reachanged a basic understanding of what is necessary to make unprivileged mounts safe in the presence of EVM and IMA xattrs which the last commit in this series reflects. While technically it is a revert the comments it adds are important for people not getting confused in the future. Clearing up that confusion allows us to seriously work on unprivileged mounts of fuse in the next development cycle. The rest of the fixes in this set are in the intersection of user namespaces, ptrace, and exec. I started with the first fix which started a feedback cycle of finding additional issues during review and fixing them. Culiminating in a fix for a bug that has been present since at least Linux v1.0. Potentially these fixes were candidates for being merged during the rc cycle, and are certainly backport candidates but enough little things turned up during review and testing that I decided they should be handled as part of the normal development process just to be certain there were not any great surprises when it came time to backport some of these fixes" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: Revert "evm: Translate user/group ids relative to s_user_ns when computing HMAC" exec: Ensure mm->user_ns contains the execed files ptrace: Don't allow accessing an undumpable mm ptrace: Capture the ptracer's creds not PT_PTRACE_CAP mm: Add a user_ns owner to mm_struct and fix ptrace permission checks

2016-12-14Remove references to dead make variable LINUX_INCLUDEPaul Bolle2-2/+2
Commit 4fd06960f120 ("Use the new x86 setup code for i386") introduced a reference to the make variable LINUX_INCLUDE. That reference got moved around a bit and copied twice and now there are three references to it. There has never been a definition of that variable. (Presumably that is because it started out as a mistyped reference to LINUXINCLUDE.) So this reference has always been an empty string. Let's remove it before it spreads any further.

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.

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 ...

Independent of whether the vma is for anonymous memory, some arches like ppc64 would like to override pmd_move_must_withdraw(). One option is to encapsulate the vma_is_anonymous() check for general architectures inside pmd_move_must_withdraw() so that is always called and architectures that need unconditional overriding can override this function. ppc64 needs to override the function when the MMU is configured to use hash PTE's.

2016-12-13lib: radix-tree: check accounting of existing slot replacement usersJohannes Weiner1-1/+1
The bug in khugepaged fixed earlier in this series shows that radix tree slot replacement is fragile; and it will become more so when not only NULL<->!NULL transitions need to be caught but transitions from and to exceptional entries as well. We need checks. Re-implement radix_tree_replace_slot() on top of the sanity-checked __radix_tree_replace(). This requires existing callers to also pass the radix tree root, but it'll warn us when somebody replaces slots with contents that need proper accounting (transitions between NULL entries, real entries, exceptional entries) and where a replacement through the slot pointer would corrupt the radix tree node counts.

2016-12-13mm: remove x86-only restriction of movable_nodeReza Arbab1-0/+24
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.

2016-12-13powerpc/mm: allow memory hotplug into a memoryless nodeReza Arbab1-12/+1
Patch series "enable movable nodes on non-x86 configs", v7. This patchset allows more configs to make use of movable nodes. When CONFIG_MOVABLE_NODE is selected, there are two ways to introduce such nodes into the system: 1. Discover movable nodes at boot. Currently this is only possible on x86, but we will enable configs supporting fdt to do the same. 2. Hotplug and online all of a node's memory using online_movable. This is already possible on any config supporting memory hotplug, not just x86, but the Kconfig doesn't say so. We will fix that. We'll also remove some cruft on power which would prevent (2). This patch (of 5): Remove the check which prevents us from hotplugging into an empty node. The original commit b226e4621245 ("[PATCH] powerpc: don't add memory to empty node/zone"), states that this was intended to be a temporary measure. It is a workaround for an oops which no longer occurs.

2016-12-13mm: remove the page size change check in tlb_remove_pageAneesh Kumar K.V5-40/+7
Now that we check for page size change early in the loop, we can partially revert e9d55e157034a ("mm: change the interface for __tlb_remove_page"). This simplies the code much, by removing the need to track the last address with which we adjusted the range. We also go back to the older way of filling the mmu_gather array, ie, we add an entry and then check whether the gather batch is full.

2016-12-13mm: add tlb_remove_check_page_size_change to track page size changeAneesh Kumar K.V6-0/+46
With commit e77b0852b551 ("mm/mmu_gather: track page size with mmu gather and force flush if page size change") we added the ability to force a tlb flush when the page size change in a mmu_gather loop. We did that by checking for a page size change every time we added a page to mmu_gather for lazy flush/remove. We can improve that by moving the page size change check early and not doing it every time we add a page. This also helps us to do tlb flush when invalidating a range covering dax mapping. Wrt dax mapping we don't have a backing struct page and hence we don't call tlb_remove_page, which earlier forced the tlb flush on page size change. Moving the page size change check earlier means we will do the same even for dax mapping. We also avoid doing this check on architecture other than powerpc. In a later patch we will remove page size check from tlb_remove_page().
