2017-05-04IB/hfi1, IB/rdmavt: Move r_adefered to r_lock cache lineMike Marciniszyn
This field is causing excessive cache line bouncing. There are spare bytes in the r_lock cache line so the best approach is to make an rvt QP field and remove from the hfi1 priv field.

2017-05-04IB/hfi1: Fix checks for Offline transient stateJakub Byczkowski
In goto_offline() function pstate is masked by 0xff when compared to PLS_OFFLINE state. Mask should be 0xf0, since upper 4 bits specify the "major" state.

2017-05-04libnvdimm: handle locked label storage areasDan Williams
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.

2017-05-04libnvdimm: convert NDD_ flags to use bitops, introduce NDD_LOCKEDDan Williams
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.

Enable mlx5 IPoIB acceleration by declaring mlx5_ib_{alloc,free}_rdma_netdev and assigning the mlx5 IPoIB rdma_netdev callbacks. In addition, this patch brings in sync mlx5's IPoIB parts for net and IB trees. As a precaution, we disabled IPoIB acceleration by default (in the mlx5_core Kconfig file).

I have decided that this is the lesser evil right now. - Make gpiod_count() behave consistently across different hardware descriptions. - Fix the syntax around open drain/open source to not infer active high/low semantics.

Driver improvements: - A whole slew of drivers have their spinlocks chaned to raw spinlocks as they provide irqchips, and thus we are progressing on realtime compliance. - Use devm_irq_alloc_descs() in a slew of drivers, getting managed resources. - Support for the embedded PWM controller inside the MVEBU driver. - Debounce, open source and open drain support for the Aspeed driver. - Misc smaller fixes like spelling and syntax and whatnot" * tag 'gpio-v4.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (77 commits) gpio: f7188x: Add a missing break gpio: omap: return error if requested debounce time is not possible gpio: Add ROHM BD9571MWV-M PMIC GPIO driver gpio: gpio-wcove: fix GPIO IRQ status mask gpio: DT bindings, move tca9554 from pcf857x to pca953x gpio: move tca9554 from pcf857x to pca953x gpio: arizona: Correct check whether the pin is an input gpio: Add XRA1403 DTS binding documentation dt-bindings: add exar to vendor prefixes list gpio: gpio-wcove: fix irq pending status bit width gpio: dwapb: use dwapb_read instead of readl_relaxed gpio: aspeed: Add open-source and open-drain support gpio: aspeed: Add debounce support gpio: aspeed: dt: Add optional clocks property gpio: aspeed: dt: Fix description alignment in bindings document gpio: mvebu: Add limited PWM support gpio: Use unsigned int for interrupt numbers gpio: f7188x: Add F71889A GPIO support. gpio: core: Decouple open drain/source flag with active low/high gpio: arizona: Correct handling for reading input GPIOs ...

dm-cache's smq policy tries hard to do it's work during the idle periods when there is no IO.

To achieve this, pass @idle=true to queue_promotion()'s free_target_met() call so that free_target_met() doesn't short-circuit the possibility of demotion simply because it isn't an idle period.

2017-05-03zram: reduce load operation in page_same_filledSangwoo Park
In page_same_filled function, all elements in the page is compared with next index value. The current comparison routine compares the (i)th and (i+1)th values of the page. In this case, two load operaions occur for each comparison. But if we store first value of the page stores at 'val' variable and using it to compare with others, the load opearation is reduced. It reduce load operation per page by up to 64times.

Patch series "zram clean up", v2. This patchset aims to clean up zram . [1] clean up multiple pages's bvec handling. [2] clean up partial IO handling [3-6] clean up zram via using accessor and removing pointless structure.

The reason is zram expects each bvec in bio contains a single page but nvme can attach a huge bulk of pages attached to the bio's bvec so that zram's index arithmetic could be wrong so that out-of-bound access makes system panic. [1] in mainline solved solved the problem by limiting max_sectors with SECTORS_PER_PAGE but it makes zram slow because bio should split with each pages so this patch makes zram aware of multiple pages in a bvec so it could solve without any regression(ie, bio split).

2017-05-03oom: improve oom disable handlingMichal Hocko
Tetsuo has reported that sysrq triggered OOM killer will print a misleading information when no tasks are selected: sysrq: SysRq : Manual OOM execution Out of memory: Kill process 4468 ((agetty)) score 0 or sacrifice child Killed process 4468 ((agetty)) total-vm:43704kB, anon-rss:1760kB, file-rss:0kB, shmem-rss:0kB sysrq: SysRq : Manual OOM execution Out of memory: Kill process 4469 (systemd-cgroups) score 0 or sacrifice child Killed process 4469 (systemd-cgroups) total-vm:10704kB, anon-rss:120kB, file-rss:0kB, shmem-rss:0kB sysrq: SysRq : Manual OOM execution sysrq: OOM request ignored because killer is disabled sysrq: SysRq : Manual OOM execution sysrq: OOM request ignored because killer is disabled sysrq: SysRq : Manual OOM execution sysrq: OOM request ignored because killer is disabled The real reason is that there are no eligible tasks for the OOM killer to select but since commit 7c5f64f84483 ("mm: oom: deduplicate victim selection code for memcg and global oom") the semantic of out_of_memory has changed without updating moom_callback. This patch updates moom_callback to tell that no task was eligible which is the case for both oom killer disabled and no eligible tasks. In order to help distinguish first case from the second add printk to both oom_killer_{enable,disable}. This information is useful on its own because it might help debugging potential memory allocation failures.

git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma Pull rdma updates from Doug Ledford: "More exchaustive description of primary updates in this release: - Lots of driver fixes and misc fixes across the board. - I had to base on a net-next tree because the IPoIB Accelorator patches needed it. Unfortunately, it was known to Mellanox that there would need to be an IPoIB accelorator patch to the net tree (which left some functions turned off by an #ifdef construct to avoid warnings about defined but unused functions), then one to the RDMA tree, then a fixup that went back and re-enabled the functions in the net tree and enabled their use in the rdma tree Also, a sparse fix was sent to the net tree after I did my pull, and the fixup patch conflicts quite directly with that sparse fix, so I'm going to submit the fixup patch towards the end of the merge window by itself and based upon your master branch at the time. - Two separate rounds of hfi1 fixes, one that got dropped from last release because it came in just a day or two before the end of the merge window and then the one from this release cycle. Of note is that I now have a third series that just landed from Intel yesterday. It is not included in this pull request, but I may submit it by the end of the week. I'll talk to Intel about improving the timing of thier submissions for my workflow. - Changes to our idr usage in the RDMA subsystem that will tie into our cgroup management and also into the upcoming changes for the RDMA kernel<->userspace API. - Addition of support for a netdev to be tied to an RDMA device at the core level - Addition of the VNIC driver from Intel. While IPoIB provides IP over InfiniBand (and *only* IP, no lower layer protocol headers are allowed or supported), the VNIC driver presents a virtual Ethernet device with support for things like varying Ethertypes, VLANs, priorities and other features of Ethernet. The virtual devices are centrally managed by the OPA fabric manager, making this (for the time being) a strictly OPA specific feature. - Improvements to the On-Demand Paging support in the RDMA subsystem. - Addition of three significant OPA changes. While we added OPA support some time ago (via the hfi1 driver), the RDMA subsystem has so far glossed over the areas where OPA and InfiniBand differ. With this release we are starting to add support for the OPA extensions into the RDMA core in the following area: Extended port information for OPA is now supported, extended Address Handle attributes for OPA are now supported, and extended SA Queries to get OPA specific subnet information is now supported. Concise summary from the tag: - idr usage and locking changes - build fix for hns - ipoib debug path record file fix - hfi1 updates - core RDMA netdev addition - Intel VNIC driver addition - Enhanced accelerators for IPoIB addition - Debug cleanups in cxgb3/4 - Trivial cleanups from SF Markus Elfring - Misc rxe fixes from Mellanox - Misc ipoib fixes from Mellanox - Lots of mlx4/mlx5 changes from Mellanox - Misc fixes across the RDMA subsystem - ODP paging fixes and improvements - qedr updates - hfi1 updates - OPA port info patches - OPA AH patches - OPA SA Query patches" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: (191 commits) infiniband: avoid dereferencing uninitialized dst on error path IB/SA: Add OPA addr header IB/mlx5: Add port_xmit_wait to counter registers read IB/ocrdma: fix out of bounds access to local buffer IB/mlx4: Fix incorrect order of formal and actual parameters IB/mlx4: Change flush logic so it adheres to the variable name mlx5: Fix mlx5_ib_map_mr_sg mr length IB/rxe: Don't clamp residual length to mtu IB/SA: Add support to query OPA path records IB/SA: Add OPA path record type IB/SA: Split struct sa_path_rec based on IB and ROCE specific fields IB/SA: Introduce path record specific types IB/SA: Rename ib_sa_path_rec to sa_path_rec IB/CM: Add braces when using sizeof IB/core: Define 'opa' rdma_ah_attr type IB/core: Define 'ib' and 'roce' rdma_ah_attr types IB/core: Use rdma_ah_attr accessor functions IB/core: Add accessor functions for rdma_ah_attr fields IB/PVRDMA: Rename ib_ah_attr related functions IB/mthca: Rename to_ib_ah_attr to to_rdma_ah_attr ...
