2018-03-08hv_netvsc: avoid repeated updates of packet filterStephen Hemminger
The netvsc driver can get repeated calls to netvsc_rx_mode during network setup; each of these calls ends up scheduling the lower layers to update tha packet filter. This update requires an request/response to the host. So avoid doing this if we already know that the correct packet filter value is set.

2018-03-08nvme_fc: rework sqsize handlingJames Smart
Corrected four outstanding issues in the transport around sqsize. 1: Create Connection LS is sending the 1's-based sqsize, should be sending the 0's-based value. 2: allocation of hw queue is using the 0's-base size. It should be using the 1's-based value. 3: normalization of ctrl.sqsize by MQES is using MQES+1 (1's-based value). It should be MQES (0's-based value). 4: Missing clause to ensure queue_count not larger than ctrl->sqsize. Corrected by: Clean up routines that pass queue size around. The queue size value is the actual count (1's-based) value and determined from ctrl->sqsize + 1. Routines that send 0's-based value adapt from queue size. Sset ctrl->sqsize properly for MQES. Added clause to nsure queue_count not larger than ctrl->sqsize + 1.

2018-03-08nvme-fabrics: Ignore nr_io_queues option for discovery controllersRoland Dreier
This removes a dependency on the order options are passed when creating a fabrics controller. With the old code, if "nr_io_queues" appears before an "nqn" option specifying the discovery controller, then nr_io_queues is overridden with zero. If "nr_io_queues" appears after specifying the discovery controller, then the nr_io_queues option is used to set the number of queues, and the driver attempts to establish IO connections to the discovery controller (which doesn't work). It seems better to ignore (and warn about) the "nr_io_queues" option if userspace has already asked to connect to the discovery controller.

2018-03-08pinctrl: samsung: Validate alias coming from DTKrzysztof Kozlowski
Driver uses alias from Device Tree as an index of pin controller data array. In case of a wrong DTB or an out-of-tree DTB, the alias could be outside of this data array leading to out-of-bounds access. Depending on binary and memory layout, this could be handled properly (showing error like "samsung-pinctrl 3860000.pinctrl: driver data not available") or could lead to exceptions.

2018-03-08pinctrl: sh-pfc: r8a7795: remove duplicate of CLKOUT pin in pinmux_pins[]Niklas Söderlund
When adding GP-1-28 port pin support it was forgotten to remove the CLKOUT pin from the list of pins that are not associated with a GPIO port in pinmux_pins[]. This results in a warning when reading the pinctrl files in sysfs as the CLKOUT pin is still added as a none GPIO pin. Fix this by removing the duplicated entry which is no longer needed. ~ # cat /sys/kernel/debug/pinctrl/e6060000.pin-controller/pinconf-pins [ 89.432081] ------------[ cut here ]------------ [ 89.436904] Pin 496 is not in bias info list [ 89.441252] WARNING: CPU: 1 PID: 456 at drivers/pinctrl/sh-pfc/core.c:408 sh_pfc_pin_to_bias_reg+0xb0/0xb8 [ 89.451002] CPU: 1 PID: 456 Comm: cat Not tainted 4.16.0-rc1-arm64-renesas-00048-gdfafc344a4f24dde #12 [ 89.460394] Hardware name: Renesas Salvator-X 2nd version board based on r8a7795 ES2.0+ (DT) [ 89.468910] pstate: 80000085 (Nzcv daIf -PAN -UAO) [ 89.473747] pc : sh_pfc_pin_to_bias_reg+0xb0/0xb8 [ 89.478495] lr : sh_pfc_pin_to_bias_reg+0xb0/0xb8 [ 89.483241] sp : ffff00000aff3ab0 [ 89.486587] x29: ffff00000aff3ab0 x28: ffff00000893c698 [ 89.491955] x27: ffff000008ad7d98 x26: 0000000000000000 [ 89.497323] x25: ffff8006fb3f5028 x24: ffff8006fb3f5018 [ 89.502690] x23: 0000000000000001 x22: 00000000000001f0 [ 89.508057] x21: ffff8006fb3f5018 x20: ffff000008bef000 [ 89.513423] x19: 0000000000000000 x18: ffffffffffffffff [ 89.518790] x17: 0000000000006c4a x16: ffff000008d67c98 [ 89.524157] x15: 0000000000000001 x14: ffff00000896ca98 [ 89.529524] x13: 00000000cce5f611 x12: ffff8006f8d3b5a8 [ 89.534891] x11: ffff00000981e000 x10: ffff000008befa08 [ 89.540258] x9 : ffff8006f9b987a0 x8 : ffff000008befa08 [ 89.545625] x7 : ffff000008137094 x6 : 0000000000000000 [ 89.550991] x5 : 0000000000000000 x4 : 0000000000000001 [ 89.556357] x3 : 0000000000000007 x2 : 0000000000000007 [ 89.561723] x1 : 1ff24f80f1818600 x0 : 0000000000000000 [ 89.567091] Call trace: [ 89.569561] sh_pfc_pin_to_bias_reg+0xb0/0xb8 [ 89.573960] r8a7795_pinmux_get_bias+0x30/0xc0 [ 89.578445] sh_pfc_pinconf_get+0x1e0/0x2d8 [ 89.582669] pin_config_get_for_pin+0x20/0x30 [ 89.587067] pinconf_generic_dump_one+0x180/0x1c8 [ 89.591815] pinconf_generic_dump_pins+0x84/0xd8 [ 89.596476] pinconf_pins_show+0xc8/0x130 [ 89.600528] seq_read+0xe4/0x510 [ 89.603789] full_proxy_read+0x60/0x90 [ 89.607576] __vfs_read+0x30/0x140 [ 89.611010] vfs_read+0x90/0x170 [ 89.614269] SyS_read+0x60/0xd8 [ 89.617443] __sys_trace_return+0x0/0x4 [ 89.621314] ---[ end trace 99c8d0d39c13e794 ]--- Fixes: 82d2de5a4f646f72 ("pinctrl: sh-pfc: r8a7795: Add GP-1-28 port pin support") Reviewed-and-tested-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Niklas Söderlund <niklas.soderlund+renesas@ragnatech.se> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2018-03-07Revert "Input: synaptics - Lenovo Thinkpad T460p devices should use RMI"Arkadiusz Hiler
This reverts commit 48282969826b3d3c76e908182f69724d86d995fe which caused the following issues: 1. On T460p with BIOS version 2.22 touchpad and trackpoint stop working after suspend-resume cycle. Due to strange state of the device another suspend is impossible. The following dmesg errors can be observed: thinkpad_acpi: EC reports that Thermal Table has changed rmi4_smbus 7-002c: failed to get SMBus version number! rmi4_physical rmi4-00: rmi_driver_reset_handler: Failed to read current IRQ mask. rmi4_f01 rmi4-00.fn01: Failed to restore normal operation: -16. rmi4_f01 rmi4-00.fn01: Resume failed with code -16. rmi4_physical rmi4-00: Failed to suspend functions: -16 rmi4_smbus 7-002c: Failed to resume device: -16 PM: resume devices took 0.640 seconds rmi4_f03 rmi4-00.fn03: rmi_f03_pt_write: Failed to write to F03 TX register (-16). rmi4_physical rmi4-00: rmi_driver_clear_irq_bits: Failed to change enabled interrupts! rmi4_physical rmi4-00: rmi_driver_set_irq_bits: Failed to change enabled interrupts! psmouse: probe of serio3 failed with error -1 2. On another T460p with BIOS version 2.15 two finger scrolling gesture on the touchpad stops working after suspend-resume cycle (about 75% reproducibility, when it still works, the scrolling gesture becomes laggy). Nothing suspicious appears in the dmesg. Analysis form Richard Schütz: "RMI is unreliable on the ThinkPad T460p because the device is affected by the firmware behavior addressed in a7ae81952cda ("i2c: i801: Allow ACPI SystemIO OpRegion to conflict with PCI BAR")."

2018-03-07libnvdimm, {btt, blk}: do integrity setup before add_disk()Vishal Verma
Prior to 25520d55cdb6 ("block: Inline blk_integrity in struct gendisk") we needed to temporarily add a zero-capacity disk before registering for blk-integrity. But adding a zero-capacity disk caused the partition table scanning to bail early, and this resulted in partitions not coming up after a probe of the BTT or blk namespaces. We can now register for integrity before the disk has been added, and this fixes the rescan problems.

Move cursor programming to inside the OTG_MASTER_UPDATE_LOCK If graphics plane go from 1 pipe to hsplit, the cursor updates after mpc programming and unlock. Which means there is a window of time where cursor is enabled on the wrong pipe if it's on the right side of the screen (i.e. case where cursor need to move from pipe 0 to pipe 3 post split). This will cause pstate hang. Solution is to program the cursor while still locked.

2018-03-07drm/amd/display: disable CRTCs with NULL FB on their primary plane (V2)Shirish S
The below commit "drm/atomic: Try to preserve the crtc enabled state in drm_atomic_remove_fb, v2" introduces a slight behavioral change to rmfb. Instead of disabling a crtc when the primary plane is disabled, it now preserves it. This change leads to BUG hit while performing atomic commit on amd driver. As a fix this patch ensures that we disable the CRTC's with NULL FB by returning -EINVAL and hence triggering fall back to the old behavior and turning off the crtc in atomic_remove_fb(). V2: Added error check for plane_state and removed sanity check for crtc.
