So they can figure out what is the optimal number of pages that can be contingously stitched together without fear of bounce buffer. We also expose an mechanism for sub-users of SWIOTLB API, such as Xen-SWIOTLB to set the max segment value. And lastly if swiotlb=force is set (which mandates we bounce buffer everything) we set max_segment so at least we can bounce buffer one 4K page instead of a giant 512KB one for which we may not have space.

2017-01-04drm: tilcdc: simplify the recovery from sync lost error on rev1Bartosz Golaszewski
Revision 2 of LCDC suffers from an issue where a SYNC_LOST error caused by limited memory bandwidth may leave the picture shifted a couple pixels to the right. This issue has not been observed on revision 1, while the recovery mechanism introduces a different issue, where the END_OF_FRAME interrupt doesn't fire while drm is waiting for vblanks. On rev1: recover from sync lost errors by simply clearing the RASTER_ENABLE bit in the RASTER_CTRL register and re-enabling it again as is suggested by the datasheet.

2017-01-03drm/i915: Force VDD off on the new power seqeuencer before starting to use itVille Syrjälä
Apparently some VLV BIOSen like to leave the VDD force bit enabled even for power seqeuncers that aren't properly hooked up to any port. That will result in a imbalance in the AUX power domain refcount when we stat to use said power sequencer as edp_panel_vdd_on() will not grab the power domain reference if it sees that the VDD is already on. To fix this let's make sure we turn off the VDD force bit when we initialize the power sequencer registers. That is, unless it's being done from the init path since there we are actually initializing the registers for the current power sequencer and we don't want to turn VDD off needlessly as that would require waiting for the power cycle delay before we turn it back on.

2016-12-29drm/msm: Ensure that the hardware write pointer is validJordan Crouse
Currently the value written to CP_RB_WPTR is calculated on the fly as (rb->next - rb->start). But as the code is designed rb->next is wrapped before writing the commands so if a series of commands happened to fit perfectly in the ringbuffer, rb->next would end up being equal to rb->size / 4 and thus result in an out of bounds address to CP_RB_WPTR. The easiest way to fix this is to mask WPTR when writing it to the hardware; it makes the hardware happy and the rest of the ringbuffer math appears to work and there isn't any point in upsetting anything.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull more ACPI updates from Rafael Wysocki: "Here are new versions of two ACPICA changes that were deferred previously due to a problem they had introduced, two cleanups on top of them and the removal of a useless warning message from the ACPI core. Specifics: - Move some Linux-specific functionality to upstream ACPICA and update the in-kernel users of it accordingly (Lv Zheng) - Drop a useless warning (triggered by the lack of an optional object) from the ACPI namespace scanning code (Zhang Rui)" * tag 'acpi-extra-4.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI / osl: Remove deprecated acpi_get_table_with_size()/early_acpi_os_unmap_memory() ACPI / osl: Remove acpi_get_table_with_size()/early_acpi_os_unmap_memory() users ACPICA: Tables: Allow FADT to be customized with virtual address ACPICA: Tables: Back port acpi_get_table_with_size() and early_acpi_os_unmap_memory() from Linux kernel ACPI: do not warn if _BQC does not exist
