git://anongit.freedesktop.org/git/drm-intel into drm-fixes Just a few minor fixes. Important one is the execbuf async fix (aka ANDROID_native_sync). There was another patch for a display coherency corner case on APL, but we've random-walked in that space too much, and the cherry-pick looked really invasive. * tag 'drm-intel-fixes-2017-06-27' of git://anongit.freedesktop.org/git/drm-intel: drm/i915: Disable EXEC_OBJECT_ASYNC when doing relocations drm/i915: Hold struct_mutex for per-file stats in debugfs/i915_gem_object drm/i915: Retire the VMA's fence tracker before unbinding

The hash table created during vmw_cmdbuf_res_man_create was never freed. This causes memory leak in context creation. Added the corresponding drm_ht_remove in vmw_cmdbuf_res_man_destroy.

2017-06-26drm/i915: Disable EXEC_OBJECT_ASYNC when doing relocationsChris Wilson1-3/+14
If we write a relocation into the buffer, we require our own implicit synchronisation added after the start of the execbuf, outside of the user's control. As we may end up clflushing, or doing the patch itself on the GPU, asynchronously we need to look at the implicit serialisation on obj->resv and hence need to disable EXEC_OBJECT_ASYNC for this object. If the user does trigger a stall for relocations, we make sure the stall is complete enough so that the batch is not submitted before we complete those relocations.

2017-06-26drm/i915: Retire the VMA's fence tracker before unbindingChris Wilson1-0/+5
Since we may track unfenced access (GPU access to the vma that explicitly requires no fence), vma->last_fence may be set without any attached fence (vma->fence) and so will not be flushed when we call i915_vma_put_fence().

2017-06-23Input: synaptics-rmi4 - only read the F54 query registers which are usedAndrew Duggan1-10/+7
The F54 driver is currently only using the first 6 bytes of F54 so there is no need to read all 27 bytes. Some Dell systems (Dell XP13 9333 and similar) have an issue with the touchpad or I2C bus when reading reports larger then 16 bytes. Reads larger then 16 bytes are reported in two HID reports. Something about the back to back reports seems to cause the next read to report incorrect data. This results in F30 failing to load and the click button failing to work.

2017-06-21ACPI / scan: Fix enumeration for special SPI and I2C devicesJarkko Nikula1-30/+37
Commit f406270bf73d ("ACPI / scan: Set the visited flag for all enumerated devices") caused that two group of special SPI or I2C devices do not enumerate. SPI and I2C devices are expected to be enumerated by the SPI and I2C subsystems but change caused that acpi_bus_attach() marks those devices with acpi_device_set_enumerated(). First group of devices are matched using Device Tree compatible property with special _HID "PRP0001". Those devices have matched scan handler, acpi_scan_attach_handler() retuns 1 and acpi_bus_attach() marks them with acpi_device_set_enumerated(). Second group of devices without valid _HID such as "LNXVIDEO" have device->pnp.type.platform_id set to zero and change again marks them with acpi_device_set_enumerated(). Fix this by flagging the SPI and I2C devices during struct acpi_device object initialization time and let the code in acpi_bus_attach() to go through the device_attach() and acpi_default_enumeration() path for all SPI and I2C devices.

If only a subset of the devices associated with multiple regions support a given special operation (eg. DISCARD) then the dec_count() that is used to set error for the region must increment the io->count. Otherwise, when the dec_count() is called it can cause the dm-io caller's bio to be completed multiple times.

gic_read_count(), gic_write_compare() and gic_write_cpu_compare() are often used in a sequence to update the compare register with a count value increased by a small offset. With small delta values used to update the compare register, the time to update function trace for these operations may be longer than the update timeout leading to update failure.

2017-06-20net: stmmac: free an skb first when there are no longer any descriptors using itNiklas Cassel1-4/+16
When having the skb pointer in the first descriptor, stmmac_tx_clean can get called at a moment where the IP has only cleared the own bit of the first descriptor, thus freeing the skb, even though there can be several descriptors whose buffers point into the same skb. By simply moving the skb pointer from the first descriptor to the last descriptor, a skb will get freed only when the IP has cleared the own bit of all the descriptors that are using that skb.

2017-06-20gpio: mvebu: change compatible string for PWM supportRalph Sennhauser1-3/+3
As it turns out more than just Armada 370 and XP support using GPIO lines as PWM lines. For example the Armada 38x family has the same hardware support. As such "marvell,armada-370-xp-gpio" for the compatible string is a misnomer. Change the compatible string to "marvell,armada-370-gpio" before the driver makes it out of the -rc stage. This also follows the practice of using only the first device family supported as part of the name. Also update the documentation and comments in the code accordingly.

2017-06-20Revert "HID: magicmouse: Set multi-touch keybits for Magic Mouse"Daniel Stone1-8/+7
Setting these bits causes libinput to fail to initialize the device; setting BTN_TOUCH and BTN_TOOL_FINGER causes it to treat the mouse as a touchpad, and it then refuses to continue when it discovers ABS_X is not set. This breaks all known Wayland compositors, as well as Xorg when the libinput driver is being used. This reverts commit f4b65b9563216b3e01a5cc844c3ba68901d9b195.
