gitolite.kernel.org:pub/scm/linux/kernel/git/nvdimm/nvdimm Pull libnvdimm memory-failure update from Dave Jiang: "As it stands, memory_failure() gets thoroughly confused by dev_pagemap backed mappings. The recovery code has specific enabling for several possible page states and needs new enabling to handle poison in dax mappings. In order to support reliable reverse mapping of user space addresses: 1/ Add new locking in the memory_failure() rmap path to prevent races that would typically be handled by the page lock. 2/ Since dev_pagemap pages are hidden from the page allocator and the "compound page" accounting machinery, add a mechanism to determine the size of the mapping that encompasses a given poisoned pfn. 3/ Given pmem errors can be repaired, change the speculatively accessed poison protection, mce_unmap_kpfn(), to be reversible and otherwise allow ongoing access from the kernel. A side effect of this enabling is that MADV_HWPOISON becomes usable for dax mappings, however the primary motivation is to allow the system to survive userspace consumption of hardware-poison via dax.

2018-08-25qlge: Fix netdev features configuration.Manish Chopra1-15/+8
qlge_fix_features() is not supposed to modify hardware or driver state, rather it is supposed to only fix requested fetures bits. Currently qlge_fix_features() also goes for interface down and up unnecessarily if there is not even any change in features set. This patch changes/fixes following - 1) Move reload of interface or device re-config from qlge_fix_features() to qlge_set_features(). 2) Reload of interface in qlge_set_features() only if relevant feature bit (NETIF_F_HW_VLAN_CTAG_RX) is changed. 3) Get rid of qlge_fix_features() since driver is not really required to fix any features bit.

2018-08-25net: macb: do not disable MDIO bus at open/close timeAnssi Hannula1-3/+6
macb_reset_hw() is called from macb_close() and indirectly from macb_open(). macb_reset_hw() zeroes the NCR register, including the MPE (Management Port Enable) bit. This will prevent accessing any other PHYs for other Ethernet MACs on the MDIO bus, which remains registered at macb_reset_hw() time, until macb_init_hw() is called from macb_open() which sets the MPE bit again. I.e. currently the MDIO bus has a short disruption at open time and is disabled at close time until the interface is opened again. Fix that by only touching the RE and TE bits when enabling and disabling RX/TX. v2: Make macb_init_hw() NCR write a single statement.

commit 739de9a1563a ("net: macb: Reorganize macb_mii bringup") broke initializing macb on the EVB-KSZ9477 eval board. There, of_mdiobus_register was called even for the fixed-link representing the RGMII-link to the switch with the result that the driver attempts to enumerate PHYs on a non-existent MDIO bus: libphy: MACB_mii_bus: probed mdio_bus f0028000.ethernet-ffffffff: fixed-link has invalid PHY address mdio_bus f0028000.ethernet-ffffffff: scan phy fixed-link at address 0 [snip] mdio_bus f0028000.ethernet-ffffffff: scan phy fixed-link at address 31 The "MDIO" bus registration succeeds regardless, having claimed the reset GPIO, and calling of_phy_register_fixed_link later on fails because it tries to claim the same GPIO: macb f0028000.ethernet: broken fixed-link specification Fix this by registering the fixed-link before calling mdiobus_register.

2018-08-25mlxsw: spectrum_switchdev: Do not leak RIFs when removing bridgeIdo Schimmel3-0/+33
When a bridge device is removed, the VLANs are flushed from each configured port. This causes the ports to decrement the reference count on the associated FIDs (filtering identifier). If the reference count of a FID is 1 and it has a RIF (router interface), then this RIF is destroyed. However, if no port is member in the VLAN for which a RIF exists, then the RIF will continue to exist after the removal of the bridge. To reproduce: # ip link add name br0 type bridge vlan_filtering 1 # ip link set dev swp1 master br0 # ip link add link br0 name br0.10 type vlan id 10 # ip address add 192.0.2.0/24 dev br0.10 # ip link del dev br0 The RIF associated with br0.10 continues to exist. Fix this by iterating over all the bridge device uppers when it is destroyed and take care of destroying their RIFs.

2018-08-25cpuidle: menu: Retain tick when shallow state is selectedRafael J. Wysocki1-1/+12
The case addressed by commit 5ef499cd571c (cpuidle: menu: Handle stopped tick more aggressively) in the stopped tick case is present when the tick has not been stopped yet too. Namely, if only two CPU idle states, shallow state A with target residency significantly below the tick boundary and deep state B with target residency significantly above it, are available and the predicted idle duration is above the tick boundary, but below the target residency of state B, state A will be selected and the CPU may spend indefinite amount of time in it, which is not quite energy-efficient. However, if the tick has not been stopped yet and the governor is about to select a shallow idle state for the CPU even though the idle duration predicted by it is above the tick boundary, it should be fine to wake up the CPU early, so the tick can be retained then and the governor will have a chance to select a deeper state when it runs next time. [Note that when this really happens, it will make the idle duration predictor believe that the CPU might be idle longer than predicted, which will make it more likely to predict longer idle durations going forward, but that will also cause deeper idle states to be selected going forward, on average, which is what's needed here.] Fixes: 87c9fe6ee495 (cpuidle: menu: Avoid selecting shallow states with stopped tick) Reported-by: Leo Yan <[email protected]> Cc: 4.17+ <[email protected]> # 4.17+: 5ef499cd571c (cpuidle: menu: Handle ...)

2018-08-24i40e: fix condition of WARN_ONCE for stat stringsJacob Keller1-1/+1
Commit 9b10df596bd4 ("i40e: use WARN_ONCE to replace the commented BUG_ON size check") introduced a warning check to make sure that the size of the stat strings was always the expected value. This code accidentally inverted the check of the data pointer. Fix this so that we accurately count the size of the stats we copied in. This fixes an erroneous WARN kernel splat that occurs when requesting ethtool statistics.

2018-08-24i40e: Fix for Tx timeouts when interface is brought up if DCB is enabledMartyna Szapar1-7/+8
If interface is connected to switch port configured for DCB there are TX timeouts when bringing up interface. Problem started appearing after adding in i40e driver code mqprio hardware offload mode. In function i40e_vsi_configure_bw_alloc was added resetting BW rate which should be executing when mqprio qdisc is removed but was also when there was no mqprio qdisc added and DCB was enabled. In this patch was added additional check for DCB flag so now when DCB is enabled the correct DCB configs from before mqprio patch are restored.

These changes address comments by Jakub Kicinski on commit 38b7e7f8ae82 ("ixgbe: Do not allow LRO or MTU change with XDP"). Change the MTU check with XDP to allow any supported value and only reject those outside of the range as opposed to rejecting any change when XDP is active. In situations where MTU size is not supported, return -EINVAL instead of -EPERM. Add checks when enabling SRIOV, DCB, or adding L2FW offloaded device as they are not supported with XDP.
