2017-02-24mm: replace FAULT_FLAG_SIZE with parameter to huge_faultDave Jiang
Since the introduction of FAULT_FLAG_SIZE to the vm_fault flag, it has been somewhat painful with getting the flags set and removed at the correct locations. More than one kernel oops was introduced due to difficulties of getting the placement correctly. Remove the flag values and introduce an input parameter to huge_fault that indicates the size of the page entry. This makes the code easier to trace and should avoid the issues we see with the fault flags where removal of the flag was necessary in the fallback paths.

2017-02-24mm,fs,dax: change ->pmd_fault to ->huge_faultDave Jiang
Patch series "1G transparent hugepage support for device dax", v2. The following series implements support for 1G trasparent hugepage on x86 for device dax. The bulk of the code was written by Mathew Wilcox a while back supporting transparent 1G hugepage for fs DAX. I have forward ported the relevant bits to 4.10-rc. The current submission has only the necessary code to support device DAX. Comments from Dan Williams: So the motivation and intended user of this functionality mirrors the motivation and users of 1GB page support in hugetlbfs. Given expected capacities of persistent memory devices an in-memory database may want to reduce tlb pressure beyond what they can already achieve with 2MB mappings of a device-dax file. We have customer feedback to that effect as Willy mentioned in his previous version of these patches [1]. [1]: https://lkml.org/lkml/2016/1/31/52 Comments from Nilesh @ Oracle: There are applications which have a process model; and if you assume 10,000 processes attempting to mmap all the 6TB memory available on a server; we are looking at the following: processes : 10,000 memory : 6TB pte @ 4k page size: 8 bytes / 4K of memory * #processes = 6TB / 4k * 8 * 10000 = 1.5GB * 80000 = 120,000GB pmd @ 2M page size: 120,000 / 512 = ~240GB pud @ 1G page size: 240GB / 512 = ~480MB As you can see with 2M pages, this system will use up an exorbitant amount of DRAM to hold the page tables; but the 1G pages finally brings it down to a reasonable level. Memory sizes will keep increasing; so this number will keep increasing. An argument can be made to convert the applications from process model to thread model, but in the real world that may not be always practical. Hopefully this helps explain the use case where this is valuable. This patch (of 3): In preparation for adding the ability to handle PUD pages, convert vm_operations_struct.pmd_fault to vm_operations_struct.huge_fault. The vm_fault structure is extended to include a union of the different page table pointers that may be needed, and three flag bits are reserved to indicate which type of pointer is in the union.

2017-02-24zram: remove waitqueue for IO doneMinchan Kim
zram_reset_device() waits for ongoing writepage pages to be completed by zram->refcount logic. However, it's pointless because before the reset, we prevent further opening of zram by zram->claim and flush all of pending IO by fsync_bdev so there should be no pending IO at the zram_reset_device(). So let's remove that code which is even broken due to the lack of wake_up elsewhere.

This is a treewide change also updating all users. - Pass a GPIO label down to gpiod_request() from fwnode_get_named_gpiod(). This makes debugfs and the userspace ABI correctly reflect the current in-kernel consumer of a pin taken using this abstraction. This is a treewide change also updating all users. - Rename devm_get_gpiod_from_child() to devm_fwnode_get_gpiod_from_child() to reflect the fact that this function is operating on a fwnode object. This is a treewide change also updating all users. - Make it possible to take multiple GPIOs in a single hog of device tree hogs. - The refactorings switching GPIO chips to use the .set_config() callback using standard pin control properties and providing a backend into the pin control subsystem that were also merged into the pin control tree naturally appear here too. Testing instrumentation: - A whole slew of cleanups and improvements to the mockup GPIO driver. We now have an extended userspace test exercising the subsystem, and we can inject interrupts etc from userspace to fully test the core GPIO functionality.

2017-02-23net/mlx4_core: Use cq quota in SRIOV when creating completion EQsJack Morgenstein
When creating EQs to handle CQ completion events for the PF or for VFs, we create enough EQE entries to handle completions for the max number of CQs that can use that EQ. When SRIOV is activated, the max number of CQs a VF (or the PF) can obtain is its CQ quota (determined by the Hypervisor resource tracker). Therefore, when creating an EQ, the number of EQE entries that the VF should request for that EQ is the CQ quota value (and not the total number of CQs available in the FW). Under SRIOV, the PF, also must use its CQ quota, because the resource tracker also controls how many CQs the PF can obtain. Using the FW total CQs instead of the CQ quota when creating EQs resulted wasting MTT entries, due to allocating more EQEs than were needed.

probed PFs In the VF driver, module parameter mlx4_log_num_mgm_entry_size was mistakenly overwritten -- and in a manner which overrode the device-managed flow steering option encoded in the parameter. log_num_mgm_entry_size is a global module parameter which affects all ConnectX-3 PFs installed on that host. If a VF changes log_num_mgm_entry_size, this will affect all PFs which are probed subsequent to the change (by disabling DMFS for those PFs).

2017-02-23net/mlx5e: Fix wrong CQE decompressionTariq Toukan
In cqe compression with striding RQ, the decompression of the CQE field wqe_counter was done with a wrong wraparound value. This caused handling cqes with a wrong pointer to wqe (rx descriptor) and creating SKBs with wrong data, pointing to wrong (and already consumed) strides/pages. The meaning of the CQE field wqe_counter in striding RQ holds the stride index instead of the WQE index. Hence, when decompressing a CQE, wqe_counter should have wrapped-around the number of strides in a single multi-packet WQE. We dropped this wrap-around mask at all in CQE decompression of striding RQ. It is not needed as in such cases the CQE compression session would break because of different value of wqe_id field, starting a new compression session. Tested: ethtool -K ethxx lro off/on ethtool --set-priv-flags ethxx rx_cqe_compress on super_netperf 16 {ipv4,ipv6} -t TCP_STREAM -m 50 -D verified no csum errors and no page refcount issues.

2017-02-23net/mlx5e: Update MPWQE stride size when modifying CQE compress stateSaeed Mahameed
When the admin enables/disables cqe compression, updating mpwqe stride size is required: CQE compress ON ==> stride size = 256B CQE compress OFF ==> stride size = 64B This is already done on driver load via mlx5e_set_rq_type_params, all we need is just to call it on arbitrary admin changes of cqe compression state via priv flags or when changing timestamping state (as it is mutually exclusive with cqe compression). This bug introduces no functional damage, it only makes cqe compression occur less often, since in ConnectX4-LX CQE compression is performed only on packets smaller than stride size. Tested: ethtool --set-priv-flags ethxx rx_cqe_compress on pktgen with 64 < pkt size < 256 and netperf TCP_STREAM (IPv4/IPv6) verify `ethtool -S ethxx | grep compress` are advancing more often (rapidly) Fixes: 7219ab34f184 ("net/mlx5e: CQE compression") Signed-off-by: Saeed Mahameed <saeedm@mellanox.com> Reviewed-by: Tariq Toukan <tariqt@mellanox.com> Cc: kernel-team@fb.com Signed-off-by: David S.

2017-02-23net/mlx5e: Fix broken CQE compression initializationTariq Toukan
Some of RQ type parameters are derived from CQE compression state flag, CQE compression flag was initialized only after RQ type parameters setup. This leads to load RQ with stride size smaller than what we want for when CQE compression is on. This bug introduces no functional damage, it only makes CQE compression occur less often, since in ConnectX4-LX CQE compression is performed only on packets smaller than stride size. Fix this by marking default status of CQE compression in PFLAG prior to calling mlx5e_set_rq_priv_params(), as it inits some fields based on it. Tested: load driver on systems where rx CQE compress will be on (MH) pktgen with 64 < pkt size < 256 and netperf TCP_STREAM (IPv4/IPv6) verify `ethtool -S ethxx | grep compress` are advancing more often (rapidly) Fixes: 2fc4bfb7250d ("net/mlx5e: Dynamic RQ type infrastructure") Signed-off-by: Tariq Toukan <tariqt@mellanox.com> Cc: kernel-team@fb.com Signed-off-by: Saeed Mahameed <saeedm@mellanox.com> Signed-off-by: David S.

2017-02-23net/mlx5e: Register/unregister vport representors on interface attach/detachSaeed Mahameed
Currently vport representors are added only on driver load and removed on driver unload. Apparently we forgot to handle them when we added the seamless reset flow feature. This caused to leave the representors netdevs alive and active with open HW resources on pci shutdown and on error reset flows. To overcome this we move their handling to interface attach/detach, so they would be cleaned up on shutdown and recreated on reset flows.
