2015-06-02Revert "iommu/amd: Don't allocate with __GFP_ZERO in alloc_coherent"Joerg Roedel
This reverts commit 5fc872c7323534e8f7dc21bab635e7a9b9659e07. The DMA-API does not strictly require that the memory returned by dma_alloc_coherent is zeroed out. For that another function (dma_zalloc_coherent) should be used. But all other x86 DMA-API implementation I checked zero out the memory, so that some drivers rely on it and break when it is not. It seems the (driver-)world is not yet ready for this change, so revert it. Signed-off-by: Joerg Roedel <jroedel@suse.de>

2015-06-01PCI: Preserve resource size during alignment reorderingYinghai Lu
In d74b9027a4da ("PCI: Consider additional PF's IOV BAR alignment in sizing and assigning"), we store additional alignment in realloc_head and take this into consideration for assignment. In __assign_resources_sorted(), we changed dev_res->res->start, then used resource_start() (which depends on res->start), so the recomputed res->end was completely bogus. Even if we'd had the correct size, the end would have been off by one. Preserve the resource size when we adjust its alignment.

Commit dff173de84958 ("bnx2x: Fix statistics locking scheme") changed the bnx2x locking around statistics state into using a mutex - but the lock is being accessed via a timer which is forbidden. [If compiled with CONFIG_DEBUG_MUTEXES, logs show a warning about accessing the mutex in interrupt context] This moves the implementation into using a semaphore [with size '1'] instead.

2015-06-01xen: netback: read hotplug script once at start of day.Ian Campbell
When we come to tear things down in netback_remove() and generate the uevent it is possible that the xenstore directory has already been removed (details below). In such cases netback_uevent() won't be able to read the hotplug script and will write a xenstore error node. A recent change to the hypervisor exposed this race such that we now sometimes lose it (where apparently we didn't ever before). Instead read the hotplug script configuration during setup and use it for the lifetime of the backend device. The apparently more obvious fix of moving the transition to state=Closed in netback_remove() to after the uevent does not work because it is possible that we are already in state=Closed (in reaction to the guest having disconnected as it shutdown). Being already in Closed means the toolstack is at liberty to start tearing down the xenstore directories. In principal it might be possible to arrange to unregister the device sooner (e.g on transition to Closing) such that xenstore would still be there but this state machine is fragile and prone to anger... A modern Xen system only relies on the hotplug uevent for driver domains, when the backend is in the same domain as the toolstack it will run the necessary setup/teardown directly in the correct sequence wrt xenstore changes.

2015-05-30bna: fix soft lock-up during firmware initialization failureIvan Vecera
Bug in the driver initialization causes soft-lockup if firmware initialization timeout is reached. Polling function bfa_ioc_poll_fwinit() incorrectly calls bfa_nw_iocpf_timeout() when the timeout is reached. The problem is that bfa_nw_iocpf_timeout() calls again bfa_ioc_poll_fwinit()... etc. The bfa_ioc_poll_fwinit() should directly send timeout event for iocpf and the same should be done if firmware download into HW fails.

2015-05-29dm: fix casting bug in dm_merge_bvec()Joe Thornber
dm_merge_bvec() was originally added in f6fccb ("dm: introduce merge_bvec_fn"). In that commit a value in sectors is converted to bytes using << 9, and then assigned to an int. This code made assumptions about the value of BIO_MAX_SECTORS. A later commit 148e51 ("dm: improve documentation and code clarity in dm_merge_bvec") was meant to have no functional change but it removed the use of BIO_MAX_SECTORS in favor of using queue_max_sectors(). At this point the cast from sector_t to int resulted in a zero value. The fallout being dm_merge_bvec() would only allow a single page to be added to a bio. This interim fix is minimal for the benefit of stable@ because the more comprehensive cleanup of passing a sector_t to all DM targets' merge function will impact quite a few DM targets.

dm-multipath accepts 0 path mapping. # echo '0 2097152 multipath 0 0 0 0' | dmsetup create newdev Such a mapping can be used to release underlying devices while still holding requests in its queue until working paths come back. However, once the multipath device is created over blk-mq devices, it rejects reloading of 0 path mapping: # echo '0 2097152 multipath 0 0 1 1 queue-length 0 1 1 /dev/sda 1' \ | dmsetup create mpath1 # echo '0 2097152 multipath 0 0 0 0' | dmsetup load mpath1 device-mapper: reload ioctl on mpath1 failed: Invalid argument Command failed With following kernel message: device-mapper: ioctl: can't change device type after initial table load. DM tries to inherit the current table type using dm_table_set_type() but it doesn't work as expected because of unnecessary check about whether the target type is hybrid or not. Hybrid type is for targets that work as either request-based or bio-based and not required for blk-mq or non blk-mq checking.

Pull m,ore md bugfixes gfrom Neil Brown: "Assorted fixes for new RAID5 stripe-batching functionality. Unfortunately this functionality was merged a little prematurely. The necessary testing and code review is now complete (or as complete as it can be) and to code passes a variety of tests and looks quite sensible. Also a fix for some recent locking changes - a race was introduced which causes a reshape request to sometimes fail.

2015-05-29NVMe: fix type warning on 32-bitArnd Bergmann
A recent change to the ioctl handling caused a new harmless warning in the NVMe driver on all 32-bit machines: drivers/block/nvme-core.c: In function 'nvme_submit_io': drivers/block/nvme-core.c:1794:29: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] In order to shup up that warning, this introduces a new temporary variable that uses a double cast to extract the pointer from an __u64 structure member.

2015-05-29dm: fix false warning in free_rq_clone() for unmapped requestsMike Snitzer
When stacking request-based dm device on non blk-mq device and device-mapper target could not map the request (error target is used, multipath target with all paths down, etc), the WARN_ON_ONCE() in free_rq_clone() will trigger when it shouldn't. The warning was added by commit aa6df8d ("dm: fix free_rq_clone() NULL pointer when requeueing unmapped request"). But free_rq_clone() with clone->q == NULL is valid usage for the case where dm_kill_unmapped_request() initiates request cleanup. Fix this false warning by just removing the WARN_ON -- it only generated false positives and was never useful in catching the intended case (completing clone request not being mapped e.g. clone->q being NULL).
