Since commit 713e9b80 ("nios2: Switch to generic __xchg()") asm/cmpxchg.h for nios2 is merely including asm-generic/cmpxchg.h. Thus, the wrapper can be omitted and the generic header can be used directly. Signed-off-by:

Since 2014, you can't successfully build kernels with GNU Make version 3.80. Example errors: $ git describe v4.11 $ make --version | head -1 GNU Make 3.80 $ make defconfig HOSTCC scripts/basic/fixdep scripts/Makefile.host:135: *** missing separator. Stop. make: *** [defconfig] Error 2 $ make ARCH=arm64 help arch/arm64/Makefile:43: *** unterminated call to function `warning': missing `)'. Stop. $ make help >/dev/null ./Documentation/Makefile.sphinx:25: Extraneous text after `else' directive ./Documentation/Makefile.sphinx:31: *** only one `else' per conditional. Stop. make: *** [help] Error 2 The first breakage was introduced by commit c8589d1e ("kbuild: handle multi-objs dependency appropriately"). Since then (i.e. v3.18), GNU Make 3.80 has not been able to compile the kernel, but nobody has ever complained aboutt (or noticed) it. Even GNU Make 3.81 is more than 10 years old. It would not hurt to match the documentation with reality instead of fixing makefiles. Signed-off-by:

Pull libnvdimm updates from Dan Williams: "The bulk of this has been in multiple -next releases. There were a few late breaking fixes and small features that got added in the last couple days, but the whole set has received a build success notification from the kbuild robot. Change summary: - Region media error reporting: A libnvdimm region device is the parent to one or more namespaces. To date, media errors have been reported via the "badblocks" attribute attached to pmem block devices for namespaces in "raw" or "memory" mode. Given that namespaces can be in "device-dax" or "btt-sector" mode this new interface reports media errors generically, i.e. independent of namespace modes or state. This subsequently allows userspace tooling to craft "ACPI 6.1 Section 9.20.7.6 Function Index 4 - Clear Uncorrectable Error" requests and submit them via the ioctl path for NVDIMM root bus devices. - Introduce 'struct dax_device' and 'struct dax_operations': Prompted by a request from Linus and feedback from Christoph this allows for dax capable drivers to publish their own custom dax operations. This fixes the broken assumption that all dax operations are related to a persistent memory device, and makes it easier for other architectures and platforms to add customized persistent memory support. - 'libnvdimm' core updates: A new "deep_flush" sysfs attribute is available for storage appliance applications to manually trigger memory controllers to drain write-pending buffers that would otherwise be flushed automatically by the platform ADR (asynchronous-DRAM-refresh) mechanism at a power loss event. Support for "locked" DIMMs is included to prevent namespaces from surfacing when the namespace label data area is locked. Finally, fixes for various reported deadlocks and crashes, also tagged for -stable. - ACPI / nfit driver updates: General updates of the nfit driver to add DSM command overrides, ACPI 6.1 health state flags support, DSM payload debug available by default, and various fixes.

This makes glock lookup faster and more bullet-proof. - Andreas also wrote a patch to revert a patch in the evict path that caused occasional deadlocks, and is no longer needed. - Andrew Price wrote a patch to re-enable fallocate for the rindex system file to enable gfs2_grow to grow properly on secondary file system grow operations. - I wrote a patch to initialize an inode number field to make certain kernel trace points more understandable. - I also wrote a patch that makes GFS2 file system "withdraw" work more like it should by ignoring operations after a withdraw that would formerly cause a BUG() and kernel panic. - I also reworked the entire truncate/delete algorithm, scrapping the old recursive algorithm in favor of a new non-recursive algorithm. This was done for performance: This way, GFS2 no longer needs to lock multiple resource groups while doing truncates and deletes of files that cross multiple resource group boundaries, allowing for better parallelism. It also solves a problem whereby deleting large files would request a large chunk of kernel memory, which resulted in a get_page_from_freelist warning. - Due to a regression found during testing, I added a new patch to correct 'GFS2: Prevent BUG from occurring when normal Withdraws occur'." * tag 'gfs2-4.12.fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2: GFS2: Allow glocks to be unlocked after withdraw GFS2: Non-recursive delete gfs2: Re-enable fallocate for the rindex Revert "GFS2: Wait for iopen glock dequeues" gfs2: Switch to rhashtable_lookup_get_insert_fast GFS2: Temporarily zero i_no_addr when creating a dinode gfs2: Don't pack struct lm_lockname gfs2: Deduplicate gfs2_{glocks,glstats}_open gfs2: Replace rhashtable_walk_init with rhashtable_walk_enter GFS2: Prevent BUG from occurring when normal Withdraws occur

This bug fixes a regression introduced by patch 0d1c7ae9. The intent of the patch was to stop promoting glocks after a file system is withdrawn due to a variety of errors, because doing so results in a BUG(). (You should be able to unmount after a withdraw rather than having the kernel panic.) Unfortunately, it also stopped demotions, so glocks could not be unlocked after withdraw, which means the unmount would hang. This patch allows function do_xmote to demote locks to an unlocked state after a withdraw, but not promote them. Signed-off-by:

Commit 28b783e4 ("xfs: bufferhead chains are invalid after end_page_writeback") fixed one use-after-free issue by pre-calculating the loop conditionals before calling bh->b_end_io() in the end_io processing loop, but it assigned 'next' pointer before checking end offset boundary & breaking the loop, at which point the bh might be freed already, and caused use-after-free.

While honouring the DMA_ATTR_FORCE_CONTIGUOUS on arm64 (commit 44176bb3: "arm64: Add support for DMA_ATTR_FORCE_CONTIGUOUS to IOMMU"), the existing uses of dma_mmap_attrs() and dma_get_sgtable() have been broken by passing a physically contiguous vm_struct with an invalid pages pointer through the common iommu API. Since the coherent allocation with DMA_ATTR_FORCE_CONTIGUOUS uses CMA, this patch simply reuses the existing swiotlb logic for mmap and get_sgtable. Note that the current implementation of get_sgtable (both swiotlb and iommu) is broken if dma_declare_coherent_memory() is used since such memory does not have a corresponding struct page. To be addressed in a subsequent patch. Fixes: 44176bb3 ("arm64: Add support for DMA_ATTR_FORCE_CONTIGUOUS to IOMMU") Reported-by:

In OpenRISC we do not have a bootloader passed initrd, but the built in initramfs does contain the /init and other binaries, including modules. The previous commit 08865514 ("initramfs: finish fput() before accessing any binary from initramfs") made a change to only call fput() if the bootloader initrd was available, this caused intermittent crashes for OpenRISC. This patch changes the fput() to happen unconditionally if any rootfs is loaded. Also, I added some comments to make it a bit more clear why we call unpack_to_rootfs() multiple times.

drm/tegra: Changes for v4.12-rc1 This contains various fixes to the host1x driver as well as a plug for a leak of kernel pointers to userspace. A fairly big addition this time around is the Video Image Composer (VIC) support that can be used to accelerate some 2D and image compositing operations. Furthermore the driver now supports FB modifiers, so we no longer rely on a custom IOCTL to set those. Finally this contains a few preparatory patches for Tegra186 support which unfortunately didn't quite make it this time, but will hopefully be ready for v4.13. * tag 'drm/tegra/for-4.12-rc1' of git://anongit.freedesktop.org/tegra/linux: gpu: host1x: Fix host1x driver shutdown gpu: host1x: Support module reset gpu: host1x: Sort includes alphabetically drm/tegra: Add VIC support dt-bindings: Add bindings for the Tegra VIC drm/tegra: Add falcon helper library drm/tegra: Add Tegra DRM allocation API drm/tegra: Add tiling FB modifiers drm/tegra: Don't leak kernel pointer to userspace drm/tegra: Protect IOMMU operations by mutex drm/tegra: Enable IOVA API when IOMMU support is enabled gpu: host1x: Add IOMMU support gpu: host1x: Fix potential out-of-bounds access iommu/iova: Fix compile error with CONFIG_IOMMU_IOVA=m iommu: Add dummy implementations for !IOMMU_IOVA MAINTAINERS: Add related headers to IOMMU section iommu/iova: Consolidate code for adding new node to iovad domain rbtree

Per the latest version of the "NVDIMM DSM Interface Example" [1], the label data retrieval routine can report a "locked" status. In this case all regions associated with that DIMM are disabled until the label area is unlocked. Provide generic libnvdimm enabling for NVDIMMs with label data area locking capabilities.

This is a preparation patch for handling locked nvdimm label regions, a new concept as introduced by the latest DSM document on pmem.io [1]. A future patch will leverage nvdimm_set_locked() at DIMM probe time to flag regions that can not be enabled. There should be no functional difference resulting from this change.
