Pull sparc fixes from David Miller: 1) With modern networking cards we can run out of 32-bit DMA space, so support 64-bit DMA addressing when possible on sparc64. From Dave Tushar. 2) Some signal frame validation checks are inverted on sparc32, fix from Andreas Larsson. 3) Lockdep tables can get too large in some circumstances on sparc64, add a way to adjust the size a bit. From Babu Moger. 4) Fix NUMA node probing on some sun4v systems, from Thomas Tai. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc: sparc: drop duplicate header scatterlist.h lockdep: Limit static allocations if PROVE_LOCKING_SMALL is defined config: Adding the new config parameter CONFIG_PROVE_LOCKING_SMALL for sparc sunbmac: Fix compiler warning sunqe: Fix compiler warnings sparc64: Enable 64-bit DMA sparc64: Enable sun4v dma ops to use IOMMU v2 APIs sparc64: Bind PCIe devices to use IOMMU v2 service sparc64: Initialize iommu_map_table and iommu_pool sparc64: Add ATU (new IOMMU) support sparc64: Add FORCE_MAX_ZONEORDER and default to 13 sparc64: fix compile warning section mismatch in find_node() sparc32: Fix inverted invalid_frame_pointer checks on sigreturns sparc64: Fix find_node warning if numa node cannot be found

Pull networking fixes from David Miller: 1) Clear congestion control state when changing algorithms on an existing socket, from Florian Westphal. 2) Fix register bit values in altr_tse_pcs portion of stmmac driver, from Jia Jie Ho. 3) Fix PTP handling in stammc driver for GMAC4, from Giuseppe CAVALLARO. 4) Fix udplite multicast delivery handling, it ignores the udp_table parameter passed into the lookups, from Pablo Neira Ayuso. 5) Synchronize the space estimated by rtnl_vfinfo_size and the space actually used by rtnl_fill_vfinfo. From Sabrina Dubroca. 6) Fix memory leak in fib_info when splitting nodes, from Alexander Duyck. 7) If a driver does a napi_hash_del() explicitily and not via netif_napi_del(), it must perform RCU synchronization as needed. Fix this in virtio-net and bnxt drivers, from Eric Dumazet. 8) Likewise, it is not necessary to invoke napi_hash_del() is we are also doing neif_napi_del() in the same code path. Remove such calls from be2net and cxgb4 drivers, also from Eric Dumazet. 9) Don't allocate an ID in peernet2id_alloc() if the netns is dead, from WANG Cong. 10) Fix OF node and device struct leaks in of_mdio, from Johan Hovold. 11) We cannot cache routes in ip6_tunnel when using inherited traffic classes, from Paolo Abeni. 12) Fix several crashes and leaks in cpsw driver, from Johan Hovold. 13) Splice operations cannot use freezable blocking calls in AF_UNIX, from WANG Cong. 14) Link dump filtering by master device and kind support added an error in loop index updates during the dump if we actually do filter, fix from Zhang Shengju. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (59 commits) tcp: zero ca_priv area when switching cc algorithms net: l2tp: Treat NET_XMIT_CN as success in l2tp_eth_dev_xmit ethernet: stmmac: make DWMAC_STM32 depend on it's associated SoC tipc: eliminate obsolete socket locking policy description rtnl: fix the loop index update error in rtnl_dump_ifinfo() l2tp: fix racy SOCK_ZAPPED flag check in l2tp_ip{,6}_bind() net: macb: add check for dma mapping error in start_xmit() rtnetlink: fix FDB size computation netns: fix get_net_ns_by_fd(int pid) typo af_unix: conditionally use freezable blocking calls in read net: ethernet: ti: cpsw: fix fixed-link phy probe deferral net: ethernet: ti: cpsw: add missing sanity check net: ethernet: ti: cpsw: fix secondary-emac probe error path net: ethernet: ti: cpsw: fix of_node and phydev leaks net: ethernet: ti: cpsw: fix deferred probe net: ethernet: ti: cpsw: fix mdio device reference leak net: ethernet: ti: cpsw: fix bad register access in probe error path net: sky2: Fix shutdown crash cfg80211: limit scan results cache size net sched filters: pass netlink message flags in event notification ...

2016-11-18sunbmac: Fix compiler warningTushar Dave2-3/+4
sunbmac uses '__u32' for dma handle while invoking kernel DMA APIs, instead of using dma_addr_t. This hasn't caused any 'incompatible pointer type' warning on SPARC because until now dma_addr_t is of type u32. However, recent changes in SPARC ATU (iommu) enables 64bit DMA and therefore dma_addr_t becomes of type u64. This makes 'incompatible pointer type' warnings inevitable. e.g. drivers/net/ethernet/sun/sunbmac.c: In function ‘bigmac_ether_init’: drivers/net/ethernet/sun/sunbmac.c:1166: warning: passing argument 3 of ‘dma_alloc_coherent’ from incompatible pointer type ./include/linux/dma-mapping.h:445: note: expected ‘dma_addr_t *’ but argument is of type ‘__u32 *’ This patch resolves above compiler warning.

Summary: - Finally, after being puzzled by a bunch of recurrent UML build failures on randconfigs from the build robot, Keno Fischer nailed it: GPIO_DEVRES is optional and depends on HAS_IOMEM even though many users just unconditionally rely on it to be available. And it *should* be available: garbage collection is nice for this and it *certainly* has nothing to do with having IOMEM. So we got rid of it, and now the UML builds should JustWork(TM). - Do not call .get_direction() on sleeping GPIO chips on the fastpath when locking GPIOs for interrupts: it is done from atomic context, no way. - Some driver fixes" * tag 'gpio-v4.9-4' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: gpio: Remove GPIO_DEVRES option gpio: tc3589x: fix up .get_direction() gpio: do not double-check direction on sleeping chips gpio: pca953x: Move memcpy into mutex lock for set multiple gpio: pca953x: Fix corruption of other gpios in set_multiple.

Most of the code has had plenty of soak time at the various vendor's testing setups, so I doubt there will be another -rc pull request this cycle.

Fix use of u32 instead of int for checking for negative errors values as pointed out by Dan Carpenter <dan.carpenter@oracle.com>. And while testing the PM runtime error path by randomly returning failed values in runtime resume, I noticed two more places that need fixing: - If pm_runtime_get_sync() fails in probe, we still need to do pm_runtime_put_sync() to keep the use count happy. We could call pm_runtime_put_noidle() on the error path, but we're just going to call pm_runtime_disable() after that so pm_runtime_put_sync() will do what we want - We should print an error if pm_runtime_get_sync() fails in cppi41_dma_alloc_chan_resources() so we know where it happens Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Fixes: 740b4be3f742 ("dmaengine: cpp41: Fix handling of error path") Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com>

2016-11-16net: dsa: b53: Fix VLAN usage and how we treat CPU portFlorian Fainelli1-12/+4
We currently have a fundamental problem in how we treat the CPU port and its VLAN membership. As soon as a second VLAN is configured to be untagged, the CPU automatically becomes untagged for that VLAN as well, and yet, we don't gracefully make sure that the CPU becomes tagged in the other VLANs it could be a member of. This results in only one VLAN being effectively usable from the CPU's perspective. Instead of having some pretty complex logic which tries to maintain the CPU port's default VLAN and its untagged properties, just do something very simple which consists in neither altering the CPU port's PVID settings, nor its untagged settings: - whenever a VLAN is added, the CPU is automatically a member of this VLAN group, as a tagged member - PVID settings for downstream ports do not alter the CPU port's PVID since it now is part of all VLANs in the system This means that a typical example where e.g: LAN ports are in VLAN1, and WAN port is in VLAN2, now require having two VLAN interfaces for the host to properly terminate and send traffic from/to.

2016-11-16IB/rxe: Fix handling of erroneous WRYonatan Cohen1-8/+13
To correctly handle a erroneous WR this fix does the following 1. Make sure the bad WQE causes a user completion event. 2. Call rxe_completer to handle the erred WQE. Before the fix, when rxe_requester found a bad WQE, it changed its status to IB_WC_LOC_PROT_ERR and exit with 0 for non RC QPs. If this was the 1st WQE then there would be no ACK to invoke the completer and this bad WQE would be stuck in the QP's send-q. On top of that the requester exiting with 0 caused rxe_do_task to endlessly invoke rxe_requester, resulting in a soft-lockup attached below. In case the WQE was not the 1st and rxe_completer did get a chance to handle the bad WQE, it did not cause a complete event since the WQE's IB_SEND_SIGNALED flag was not set. Setting WQE status to IB_SEND_SIGNALED is subject to IBA spec version 1.2.1, section 10.7.3.1 Signaled Completions. NMI watchdog: BUG: soft lockup - CPU#7 stuck for 22s!
