Pull IOMMU updates from Joerg Roedel: - support for interrupt virtualization in the AMD IOMMU driver. These patches were shared with the KVM tree and are already merged through that tree. - generic DT-binding support for the ARM-SMMU driver. With this the driver now makes use of the generic DMA-API code. This also required some changes outside of the IOMMU code, but these are acked by the respective maintainers. - more cleanups and fixes all over the place. * tag 'iommu-updates-v4.9' of git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu: (40 commits) iommu/amd: No need to wait iommu completion if no dte irq entry change iommu/amd: Free domain id when free a domain of struct dma_ops_domain iommu/amd: Use standard bitmap operation to set bitmap iommu/amd: Clean up the cmpxchg64 invocation iommu/io-pgtable-arm: Check for v7s-incapable systems iommu/dma: Avoid PCI host bridge windows iommu/dma: Add support for mapping MSIs iommu/arm-smmu: Set domain geometry iommu/arm-smmu: Wire up generic configuration support Docs: dt: document ARM SMMU generic binding usage iommu/arm-smmu: Convert to iommu_fwspec iommu/arm-smmu: Intelligent SMR allocation iommu/arm-smmu: Add a stream map entry iterator iommu/arm-smmu: Streamline SMMU data lookups iommu/arm-smmu: Refactor mmu-masters handling iommu/arm-smmu: Keep track of S2CR state iommu/arm-smmu: Consolidate stream map entry state iommu/arm-smmu: Handle stream IDs more dynamically iommu/arm-smmu: Set PRIVCFG in stage 1 STEs iommu/arm-smmu: Support non-PCI devices with SMMUv3 ...

Pull libnvdimm updates from Dan Williams: "Aside from the recently added pmem sub-division support these have been in -next for several releases with no reported issues. The sub- division support was included in next-20161010 with no reported issues. It passes all unit tests including new tests for all the new functionality below. Summary: - PMEM sub-division support: Allow a single PMEM region to be divided into multiple namespaces. Originally, ~2 years ago, it was thought that partitions of a /dev/pmemX block device could handle sub-allocations of persistent memory for different use cases. With the decision to not support DAX mappings of raw block-devices, and the genesis of device-dax, the need for having multiple pmem-namespace per region has grown. - Device-DAX unified inode: In support of dynamic-resizing of a device-dax instance the kernel arranges for all mappings of a device-dax node to share the same inode. This allows unmap / truncate / invalidation events to affect all instances of the device similar to the behavior of mmap on block devices. - Hardware error scrubbing reworks: The original address-range-scrub and badblocks tracking solution allowed clearing entries at the individual namespace level, but it failed to clear the internal list of media errors maintained at the bus level. The result was that the next scrub or namespace disable/re-enable event would restore the cleared badblocks, but now that is fixed. The v4.8 kernel introduced an auto-scrub-on-machine-check behavior to repopulate the badblocks list. Now, in v4.9, the auto-scrub behavior can be disabled and simply arrange for the error reported in the machine-check to be added to the list. - DIMM health-event notification support: ACPI 6.1 defines a notification event code that can be send to ACPI NVDIMM devices. A poll(2) capable file descriptor for these events can be obtained from the nmemX/nfit/flags sysfs-attribute of a libnvdimm memory device. - Miscellaneous fixes: NVDIMM-N probe error, device-dax build error, and a change to dedup the flush hint list to not flush the memory controller more than necessary" * tag 'libnvdimm-for-4.9' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm: (39 commits) /dev/dax: fix Kconfig dependency build breakage dax: use correct dev_t value dax: convert devm_create_dax_dev to PTR_ERR libnvdimm, namespace: allow creation of multiple pmem-namespaces per region libnvdimm, namespace: lift single pmem limit in scan_labels() libnvdimm, namespace: filter out of range labels in scan_labels() libnvdimm, namespace: enable allocation of multiple pmem namespaces libnvdimm, namespace: update label implementation for multi-pmem libnvdimm, namespace: expand pmem device naming scheme for multi-pmem libnvdimm, region: update nd_region_available_dpa() for multi-pmem support libnvdimm, namespace: sort namespaces by dpa at init libnvdimm, namespace: allow multiple pmem-namespaces per region at scan time tools/testing/nvdimm: support for sub-dividing a pmem region libnvdimm, namespace: unify blk and pmem label scanning libnvdimm, namespace: refactor uuid_show() into a namespace_to_uuid() helper libnvdimm, label: convert label tracking to a linked list libnvdimm, region: move region-mapping input-paramters to nd_mapping_desc nvdimm: reduce duplicated wpq flushes libnvdimm: clear the internal poison_list when clearing badblocks pmem: reduce kmap_atomic sections to the memcpys only ...

looking for duplicate ->iov_base makes sense only for iovec-backed iterators; for kvec-backed ones it's pointless, for bvec-backed ones it's pointless and broken on 32bit (we walk through an array of struct bio_vec accessing them as if they were struct iovec; works by accident on 64bit, but on 32bit it'll blow up) and for pipe-backed ones it's pointless and ends up oopsing.

by making sure we call iov_iter_advance() on original iov_iter even if direct_IO (done on its copy) has returned 0. It's a no-op for old iov_iter flavours and does the right thing (== truncation of the stuff we'd allocated, but not filled) in ITER_PIPE case. Failures (e.g. -EIO) get caught and dealt with by cleanup in generic_file_read_iter(). Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

Merge my system logging cleanups, triggered by the broken '\n' patches. The line continuation handling has been broken basically forever, and the code to handle the system log records was both confusing and dubious. And it would do entirely the wrong thing unless you always had a terminating newline, partly because it couldn't actually see whether a message was marked KERN_CONT or not (but partly because the LOG_CONT handling in the recording code was rather confusing too). This re-introduces a real semantically meaningful KERN_CONT, and fixes the few places I noticed where it was missing. There are probably more missing cases, since KERN_CONT hasn't actually had any semantic meaning for at least four years (other than the checkpatch meaning of "no log level necessary, this is a continuation line"). This also allows the combination of KERN_CONT and a log level. In that case the log level will be ignored if the merging with a previous line is successful, but if a new record is needed, that new record will now get the right log level. That also means that you can at least in theory combine KERN_CONT with the "pr_info()" style helpers, although any use of pr_fmt() prefixing would make that just result in a mess, of course (the prefix would end up in the middle of a continuing line). * printk-cleanups: printk: make reading the kernel log flush pending lines printk: re-organize log_output() to be more legible printk: split out core logging code into helper function printk: reinstate KERN_CONT for printing continuation lines

After backporting commit ee44b4bc ("dlm: use sctp 1-to-1 API") series to a kernel with an older workqueue which didn't use RCU yet, it was noticed that we are freeing the workqueues in dlm_lowcomms_stop() too early as free_conn() will try to access that memory for canceling the queued works if any. This issue was introduced by commit 0d737a8c as before it such attempt to cancel the queued works wasn't performed, so the issue was not present. This patch fixes it by simply inverting the free order.

That will mean that any possible subsequent continuation will now be broken up onto a line of its own (since reading the log has finalized the beginning og the line), but if user space has activated system logging (or if there's a kernel message dump going on) that is the right thing to do. And now that we actually get the continuation flags _right_ for this all, the user space logger that is reading the kernel messages can actually see the continuation marker. Not that anybody seems to really bother with it (or care), but in theory user space can do its own message stitching. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
