2016-07-20block: add QUEUE_FLAG_DAX for devices to advertise their DAX supportToshi Kani
Currently, presence of direct_access() in block_device_operations indicates support of DAX on its block device. Because block_device_operations is instantiated with 'const', this DAX capablity may not be enabled conditinally. In preparation for supporting DAX to device-mapper devices, add QUEUE_FLAG_DAX to request_queue flags to advertise their DAX support. This will allow to set the DAX capability based on how mapped device is composed.

2016-07-20Input: tsc200x - report proper input_dev nameMichael Welling
Passes input_id struct to the common probe function for the tsc200x drivers instead of just the bustype. This allows for the use of the product variable to set the input_dev->name variable according to the type of touchscreen used. Note that when we introduced support for TSC2004 we started calling everything TSC200X, so let's keep this quirk.

2016-07-20tty/vt/keyboard: fix OOB access in do_compute_shiftstate()Dmitry Torokhov
The size of individual keymap in drivers/tty/vt/keyboard.c is NR_KEYS, which is currently 256, whereas number of keys/buttons in input device (and therefor in key_down) is much larger - KEY_CNT - 768, and that can cause out-of-bound access when we do sym = U(key_maps[0][k]); with large 'k'. To fix it we should not attempt iterating beyond smaller of NR_KEYS and KEY_CNT. Also while at it let's switch to for_each_set_bit() instead of open-coding it.

2016-07-20scsi/osd: open code blk_make_requestChristoph Hellwig
I wish the OSD code could simply use blk_rq_map_* helpers like everyone else, but the complex nature of deciding if we have DATA IN and/or DATA OUT buffers might make this impossible (at least for a mere human like me). But using blk_rq_append_bio at least allows sharing the setup code between request with or without dat a buffers, and given that this is the last user of blk_make_request it allows getting rid of that somewhat awkward interface.

2016-07-20block: ensure bios return from blk_get_request are properly initializedChristoph Hellwig
blk_get_request is used for BLOCK_PC and similar passthrough requests. Currently we always need to call blk_rq_set_block_pc or an open coded version of it to allow appending bios using the request mapping helpers later on, which is a somewhat awkward API. Instead move the initialization part of blk_rq_set_block_pc into blk_get_request, so that we always have a safe to use request.

These two are confusing leftover of the old world order, combining values of the REQ_OP_ and REQ_ namespaces. For callers that don't special case we mostly just replace bi_rw with bio_data_dir or op_is_write, except for the few cases where a switch over the REQ_OP_ values makes more sense.

2016-07-20block: introduce BLKDEV_DISCARD_ZERO to fix zerooutChristoph Hellwig
Currently blkdev_issue_zeroout cascades down from discards (if the driver guarantees that discards zero data), to WRITE SAME and then to a loop writing zeroes. Unfortunately we ignore run-time EOPNOTSUPP errors in the block layer blkdev_issue_discard helper to work around DM volumes that may have mixed discard support underneath. This patch intoroduces a new BLKDEV_DISCARD_ZERO flag to blkdev_issue_discard that indicates we are called for zeroing operation. This allows both to ignore the EOPNOTSUPP hack and actually consolidating the discard_zeroes_data check into the function. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Martin K.

2016-07-20libata-scsi: better style in ata_msense_*()Tom Yan
`changeable` is the "version" of mode page requested by the user. It will be less confusing/misleading if we do not check it "together" with the setting bits of the drive. Not to mention that we currently have ata_mselect_*() implemented in a way that each of them will serve exclusively a particular bit on each page. The old style will hence make the condition look even more unnecessarily arcane if the ata_msense_*() is reflecting more than one bit.

2016-07-20AHCI: Clear GHC.IS to prevent unexpectly asserting INTxPang Raymond
Due to PCI subsystem behaviour, unloading AHCI driver will disable MSI and enable INTx. When HBA supports MSIx or Multiple MSI, Driver's irq handler doesn't clear GHC.IS register. It works well when reading or writing data and GHC.IS is always non-zero. But when unloading driver (or any other operation which causes disable MSIx and enable INTx), PCI subsystem uses config write(Rx04.bit10) to enable INTx. Because GHC.IS is non-zero, HBA will falsely assume some port needs interrupt service. Then it asserts INTx. To make things worse, when AHCI controller shares the same interrupt pin with other PCI device, that PCI device's ISR will be called and nobody de-asserts previous INTx. This patch clears GHC.IS in ahci_port_stop() even when using MSIx or MMSI to prevent this case. It ensures GHC.IS is zero before PCI subsystem enables INTx. tj: Minor updates to the comment.

Tariq Toukan says: ==================== Safe flow for mlx4_en configuration change This patchset improves the mlx4_en driver resiliency, especially on systems with low memory. Upon a configuration change that requires the allocation of new resources, we first try to allocate, prior to destroying the current ones. Once it is successfully done, we release the old resources and attach the new ones. Otherwise, we stay with a functioning interface having the same old configuration. This improvement became of greater significance after removing the use of vmap. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

This patch fixes the lost of Ethernet port on low memory system, when driver frees its resources and fails to allocate new resources. Issue could happen while changing number of channels, rings size or changing the timestamp configuration. This fix is necessary because of removing vmap use in the code. When vmap was in use driver could allocate non-contiguous memory and make it contiguous with vmap. Now it could fail to allocate a large chunk of contiguous memory and lose the port. Current code tries to allocate new resources and then upon success frees the old resources.

Unfortunately warnings generated after parsing in sphinx can end up with entirely bogus files and line numbers as sources. Strangely for outright errors this is not a problem. Trying to convert warnings to errors also doesn't fix it. The only way to get useful output out of sphinx to be able to root cause the error seems to be enabling keep_warnings, which inserts a System Message into the actual output. Not pretty at all, but I don't really want to fix up core rst/sphinx code, and this gets the job done meanwhile.

Commit 4995734e973a "acpi, nfit: fix acpi_check_dsm() vs zero functions implemented" attempted to fix a QEMU regression by supporting its usage of a zero-mask as a valid response to a DSM-family probe request. However, this behavior breaks HP platforms that return a zero-mask by default causing the probe to misidentify the DSM-family. Instead, the QEMU regression can be fixed by simply not requiring the DSM family to be identified. This effectively reverts commit 4995734e973a, and removes the DSM requirement from the init path.

2016-07-19crypto: marvell - Fix wrong flag used for GFP in mv_cesa_dma_add_iv_opRomain Perier
Use the parameter 'gfp_flags' instead of 'flag' as second argument of dma_pool_alloc(). The parameter 'flag' is for the TDMA descriptor, its content has no sense for the allocator.

git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo: User visible changes: - Properly report when a function wildcard produces no matches in 'perf probe' (Masami Hiramatsu) - Balance opening and reading events in 'perf stat', which could cause it to get stuck trying to close invalid file descriptors (Mark Rutland) Infrastructure changes: - Copy more headers from the kernel, this time for headers that were just including the contents of its kernel counterparts, should help resolving the problems with linux-next, where some uapi related patches seem to be breaking tools/object/ build. (Arnaldo Carvalho de Melo) Some more combing will be done, but at least it is possible to build perf out of tree, via a detached tarball (make help | grep perf), without including kernel files in its MANIFEST (Arnaldo Carvalho de Melo) - Fix smatch found errors that were not causing problems, but are mistakes nonetheless (Dan Carpenter) - Fix string vs. byte array resolving in the python script code (Jiri Olsa) Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Ingo Molnar <mingo@kernel.org>
