2019-01-18amd-xgbe: Fix mdio access for non-zero ports and clause 45 PHYsLendacky, Thomas2-8/+16
The XGBE hardware has support for performing MDIO operations using an MDIO command request. The driver mistakenly uses the mdio port address as the MDIO command request device address instead of the MDIO command request port address. Additionally, the driver does not properly check for and create a clause 45 MDIO command. Check the supplied MDIO register to determine if the request is a clause 45 operation (MII_ADDR_C45). For a clause 45 operation, extract the device address and register number from the supplied MDIO register and use them to set the MDIO command request device address and register number fields. For a clause 22 operation, the MDIO request device address is set to zero and the MDIO command request register number is set to the supplied MDIO register. In either case, the supplied MDIO port address is used as the MDIO command request port address.

2019-01-18vhost: log dirty page correctlyJason Wang3-16/+87
Vhost dirty page logging API is designed to sync through GPA. But we try to log GIOVA when device IOTLB is enabled. This is wrong and may lead to missing data after migration. To solve this issue, when logging with device IOTLB enabled, we will: 1) reuse the device IOTLB translation result of GIOVA->HVA mapping to get HVA, for writable descriptor, get HVA through iovec. For used ring update, translate its GIOVA to HVA 2) traverse the GPA->HVA mapping to get the possible GPA and log through GPA. Pay attention this reverse mapping is not guaranteed to be unique, so we should log each possible GPA in this case. This fix the failure of scp to guest during migration. In -next, we will probably support passing GIOVA->GPA instead of GIOVA->HVA.

2019-01-17PCI: Fix __initdata issue with "pci=disable_acs_redir" parameterLogan Gunthorpe1-1/+2
The disable_acs_redir parameter stores a pointer to the string passed to pci_setup(). However, the string passed to PCI setup is actually a temporary copy allocated in static __initdata memory. After init, once the memory is freed, it is no longer valid to reference this pointer. This bug was noticed in v5.0-rc1 after a change in commit c5eb1190074c ("PCI / PM: Allow runtime PM without callback functions") caused pci_disable_acs_redir() to be called during shutdown which manifested as an unable to handle kernel paging request at: RIP: 0010:pci_enable_acs+0x3f/0x1e0 Call Trace: pci_restore_state.part.44+0x159/0x3c0 pci_restore_standard_config+0x33/0x40 pci_pm_runtime_resume+0x2b/0xd0 ? pci_restore_standard_config+0x40/0x40 __rpm_callback+0xbc/0x1b0 rpm_callback+0x1f/0x70 ? pci_restore_standard_config+0x40/0x40 rpm_resume+0x4f9/0x710 ? pci_conf1_read+0xb6/0xf0 ? pci_conf1_write+0xb2/0xe0 __pm_runtime_resume+0x47/0x70 pci_device_shutdown+0x1e/0x60 device_shutdown+0x14a/0x1f0 kernel_restart+0xe/0x50 __do_sys_reboot+0x1ee/0x210 ? __fput+0x144/0x1d0 do_writev+0x5e/0xf0 ? do_writev+0x5e/0xf0 do_syscall_64+0x48/0xf0 entry_SYSCALL_64_after_hwframe+0x44/0xa9 It was also likely possible to trigger this bug when hotplugging PCI devices.

2019-01-16nvme-pci: fix nvme_setup_irqs()Ming Lei1-8/+13
When -ENOSPC is returned from pci_alloc_irq_vectors_affinity(), we still try to allocate multiple irq vectors again, so irq queues covers the admin queue actually. But we don't consider that, then number of the allocated irq vector may be same with sum of io_queues[HCTX_TYPE_DEFAULT] and io_queues[HCTX_TYPE_READ], this way is obviously wrong, and finally breaks nvme_pci_map_queues(), and warning from pci_irq_get_affinity() is triggered. IRQ queues should cover admin queues, this patch makes this point explicitely in nvme_calc_io_queues(). We got severl boot failure internal report on aarch64, so please consider to fix it in v4.20.

2019-01-16media: vim2m: only cancel work if it is for right contextHans Verkuil1-1/+3
cancel_delayed_work_sync() was called for any queue, but it should only be called for the queue that is associated with the currently running job. Otherwise, if two filehandles are streaming at the same time, then closing the first will cancel the work which might still be running for a job from the second filehandle. As a result the second filehandle will never be able to finish the job and an attempt to stop streaming on that second filehandle will stall.

Currently the IOCTL code clears everything after the per-plane bytesperline field in struct v4l2_format.

2019-01-16phy: ath79-usb: Fix the main reset name to match the DT bindingAlban Bedel1-1/+1
I submitted this driver several times before it got accepted. The first series hasn't been accepted but the DTS binding did made it. I then made a second series that added generic reset support to the PHY core, this in turn required a change to the DT binding. This second series seemed to have been ignored, so I did a third one without the change to the PHY core and the DT binding update, and this last attempt finally made it. But two months later the DT binding update from the second series has been integrated too. So now the driver doesn't match the binding and the only DTS using it. This patch fix the driver to match the new binding. Signed-off-by: Alban Bedel <albeu@free.fr> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>

2019-01-16phy: fix build breakage: add PHY_MODE_SATAJohn Hubbard1-2/+3
Commit 49e54187ae0b ("ata: libahci_platform: comply to PHY framework") uses the PHY_MODE_SATA, but that enum had not yet been added. This caused a build failure for me, with today's linux.git. Also, there is a potentially conflicting (mis-named) PHY_MODE_SATA, hiding in the Marvell Berlin SATA PHY driver. Fix the build by: 1) Renaming Marvell's defined value to a more scoped name, in order to avoid any potential conflicts: PHY_BERLIN_MODE_SATA. 2) Adding the missing enum, which was going to be added anyway as part of [1].
