commit ecf1e225 upstream. Instead of the one when another syscall takes place while another is being processed (in another CPU, but we show it serialized, so need to "interrupt" the other), and also when finally showing the sys_enter + sys_exit + duration, where we were showing the sample->time for the sys_exit, duh.

commit 1f22e454 upstream. According to the firmware spec, FLOW_STEERING_IB_UC_QP_RANGE command is supported only if dmfs_ipoib bit is set. If it isn't set we want to ensure allocating NET_IF QPs fail. We do so by filling out the allocation bitmap. By thus, the NET_IF QPs allocating function won't find any free QP and will fail.

commit befcabcd upstream. If OpenSM runs over a ConnectX-3, and there are ConnectX-4 or Connect-IB VFs active on the network, the OpenSM will receive QP1 packets containing a GRH where the destination GID is the "Well-Known GID" -- which is not a GID in the HCA Port's GID Table. This GID must be tested-for separately -- and packets which contain this destination GID should be routed to slave 0 (the PF).

commit c482af64 upstream. For non-special QPs, the port value becomes non-zero only at the RESET-to-INIT transition. If the QP has not undergone that transition, its port number value is still zero. If such a QP is destroyed before being moved out of the RESET state, subtracting one from the qp port number results in a negative value. Using that negative value as an index into the qp1_proxy array results in an out-of-bounds array reference. Fix this by testing that the QP type is one that uses qp1_proxy before using the port number. For special QPs of all types, the port number is specified at QP creation time.

commit afd02cd3 upstream. When enabling many VFs, the total amount of DMA mappings increase significantly. This causes DMA allocations to take a lot of time since they are serialized in the kernel. As a result the driver enters into fatal condition due to timeout and the system hangs. To recover from this we disable MR cache for VFs. PFs will still have a full cache and VFs cache can be manipulated as usual after driver load. Fixes: e126ba97 ('mlx5: Add driver for Mellanox Connect-IB adapters') Signed-off-by:

commit 5d7400c4 upstream. Always stating PIN_CONFIG_BIAS_DISABLE is supported gives untrue output when examining /sys/kernel/debug/pinctrl/e6060000.pfc/pinconf-pins if the operation get_bias() is implemented but the pin is not handled by the get_bias() implementation. In that case the output will state that "input bias disabled" indicating that this pin has bias control support. Make support for PIN_CONFIG_BIAS_DISABLE depend on that the pin either supports SH_PFC_PIN_CFG_PULL_UP or SH_PFC_PIN_CFG_PULL_DOWN. This also solves the issue where SoC specific implementations print error messages if their particular implementation of {set,get}_bias() is called with a pin it does not know about. Signed-off-by:

commit 20156ce2 upstream. The find_num_contig() will return 1 when the pmd is not present. It will cause a kernel dead loop in the following scenaro: 1.) pmd entry is not present. 2.) the page fault occurs: ... hugetlb_fault() --> hugetlb_no_page() --> set_huge_pte_at() 3.) set_huge_pte_at() will only set the first PMD entry, since the find_num_contig just return 1 in this case. So the PMD entries are all empty except the first one. 4.) when kernel accesses the address mapped by the second PMD entry, a new page fault occurs: ... hugetlb_fault() --> huge_ptep_set_access_flags() The second PMD entry is still empty now. 5.) When the kernel returns, the access will cause a page fault again. The kernel will run like the "4)" above. We will see a dead loop since here. The dead loop is caught in the 32M hugetlb page (2M PMD + Contiguous bit). This patch removes wrong pmd check, and fixes this dead loop. This patch also removes the redundant checks for PGD/PUD in the find_num_contig(). Acked-by:

commit d4791db5 upstream. Whenever a PE is initialised in powernv, opal_pci_eeh_freeze_clear() is called. This is to remove any existing freeze, and has no negative side effects if the PE is already in an unfrozen state. On PHB backends that don't support this operation and return OPAL_UNSUPPORTED, this creates a scary and misleading warning message. Skip the warning message on init if OPAL_UNSUPPORTED is returned. As far as I'm aware, this currently only affects NPUs. Fixes: 313483dd ("powerpc/powernv: Unfreeze PE on allocation") Signed-off-by:

commit 555c1632 upstream. Version 3.00 of the ISA states that the PATS (partition table size) field of the PTCR (partition table control register) and the PRTS (process table size) field of the partition table entry must both be less than or equal to 24. However the actual size of the partition and process tables is equal to 2 to the power of 12 plus the PATS and PRTS fields, respectively. This means that the max allowable size of each of these tables is 2^36 or 64GB for both. Thus when checking the size shift for each we should be checking for values of greater than 36 instead of the current check for shifts larger than 24 and 23. Fixes: 2bfd65e4Signed-off-by:

commit c02ebfdd upstream. Commit 0e87e58b ("blk-mq: improve warning for running a queue on the wrong CPU") attempts to avoid triggering the WARN_ON in __blk_mq_run_hw_queue when the expected CPU is dead. Problem is, in the last batch execution before round robin, blk_mq_hctx_next_cpu can schedule a dead CPU and also update next_cpu to the next alive CPU in the mask, which will trigger the WARN_ON despite the previous workaround. The following patch fixes this scenario by always scheduling the value in hctx->next_cpu. This changes the moment when we round-robin the CPU running the hctx, but it really doesn't matter, since it still executes BLK_MQ_CPU_WORK_BATCH times in a row before switching to another CPU.

The GHES NMI handler, ghes_notify_nmi() runs the ghes_proc_irq_work work queue which ends up setting IRQ_WORK_VECTOR (0xf6). The "faulty" IR line set at arch/x86/kernel/apic/apic.c:1349 is also 0xf6 (specifically APIC IRR for irqs 255 to 224 is 0x400000) which confirms that something has set the IRQ_WORK_VECTOR line prior to the APIC being initialized. Commit 2383844d ("GHES: Elliminate double-loop in the NMI handler") incorrectly modified the behavior such that the handler returns NMI_HANDLED only if an error was processed, and incorrectly runs the ghes work queue for every NMI. This patch modifies the ghes_proc_irq_work() to run as it did prior to 2383844d ("GHES: Elliminate double-loop in the NMI handler") by properly returning NMI_HANDLED and only calling the work queue if NMI_HANDLED has been set.

commit 9a05e754 upstream.

commit 6b243fcf upstream. This changes the way that we support the new ISA v3.00 HPTE format. Instead of adapting everything that uses HPTE values to handle either the old format or the new format, depending on which CPU we are on, we now convert explicitly between old and new formats if necessary in the low-level routines that actually access HPTEs in memory. This limits the amount of code that needs to know about the new format and makes the conversions explicit. This is OK because the old format contains all the information that is in the new format. This also fixes operation under a hypervisor, because the H_ENTER hypercall (and other hypercalls that deal with HPTEs) will continue to require the HPTE value to be supplied in the old format. At present the kernel will not boot in HPT mode on POWER9 under a hypervisor. This fixes and partially reverts commit 50de596d ("powerpc/mm/hash: Add support for Power9 Hash", 2016-04-29).

commit 6de1a507 upstream. The tie between the main WCNSS driver and the IRIS driver causes a circular dependency between the two modules. Neither part makes sense to have on their own so lets merge them into one module. For the sake of picking up the clock and regulator resources described in the iris of_node we need an associated struct device. But, to keep the size of the patch down we continue to represent the IRIS part as its own platform_driver, within the same module, rather than setting up a dummy device.
