2016-11-11drm/tegra: Support kernel mappings with IOMMUArto Merilainen
host1x command buffer patching requires that the buffer object can be mapped into kernel address space. However, the recent addition of IOMMU support did not account for this requirement. Therefore host1x engines cannot be used if IOMMU is enabled. This patch implements kmap, kunmap, mmap and munmap functions to host1x buffer objects.

2016-11-11gpu: host1x: Add locking to syncptArto Merilainen
Currently syncpoints are not locked by mutex and this causes races if we are aggressively freeing and allocating syncpoints. This patch adds missing mutex protection to syncpoint structures.

2016-11-11gpu: host1x: Store device address to all bufsArto Merilainen
Currently job pinning is optimized to handle only the first buffer using a certain host1x_bo object and all subsequent buffers using the same host1x_bo are considered done. In most cases this is correct, however, in case the same host1x_bo is used in multiple gathers inside the same job, we skip also storing the device address (physical or iova) to this buffer. This patch reworks the host1x_job_pin() to store the device address to all gathers.

2016-11-11ALSA: hda - Fix mic regression by ASRock mobo fixupTakashi Iwai
The commit [1a3f099101b8: ALSA: hda - Fix surround output pins for ASRock B150M mobo] introduced a fixup of pin configs for ASRock mobos to fix the surround outputs. However, this overrides the pin configs of the mic pins as if they are outputs-only, effectively disabling the mic inputs. Of course, it's a regression wrt mic functionality. Actually the pins 0x18 and 0x1a don't need to be changed; we just need to disable the bogus pins 0x14 and 0x15. Then the auto-parser will pick up mic pins as switchable and assign the surround outputs there. This patch removes the incorrect pin overrides of NID 0x18 and 0x1a from the ASRock fixup.

Once we've determined that the sink is MST capable we never end up running through the full detect cycle again, despite getting HPDs. Fix tht by ripping out the incorrect piece of code responsible. This got broken when I moved the long HPD handling to the ->detect() hook, but failed to remove the leftover code.

2016-11-11drm/i915: Mark CPU cache as dirty when used for renderingChris Wilson
On LLC, or even snooped, machines rendering via the GPU ends up in the CPU cache. This cacheline dirt also needs to be flushed to main memory when moving to an incoherent domain, such as the display's scanout engine. Mostly, this happens because either the object is marked as dirty from its first use or is avoided by setting the object into the display domain from the start. v2: Treat WT as not requiring a clflush prior to use on the display engine as well.

2016-11-11PM / sleep: don't suspend parent when async child suspend_{noirq, late} failsBrian Norris
Consider two devices, A and B, where B is a child of A, and B utilizes asynchronous suspend (it does not matter whether A is sync or async). If B fails to suspend_noirq() or suspend_late(), or is interrupted by a wakeup (pm_wakeup_pending()), then it aborts and sets the async_error variable. However, device A does not (immediately) check the async_error variable; it may continue to run its own suspend_noirq()/suspend_late() callback. This is bad. We can resolve this problem by doing our error and wakeup checking (particularly, for the async_error flag) after waiting for children to suspend, instead of before. This also helps align the logic for the noirq and late suspend cases with the logic in __device_suspend(). It's easy to observe this erroneous behavior by, for example, forcing a device to sleep a bit in its suspend_noirq() (to ensure the parent is waiting for the child to complete), then return an error, and watch the parent suspend_noirq() still get called. (Or similarly, fake a wakeup event at the right (or is it wrong?) time.)

Splice read/write implementation changed recently. When using generic_file_splice_read(), iov_iter with type == ITER_PIPE is passed to filesystem's read_iter callback.

2016-11-10mlxsw: spectrum_router: Ignore FIB notification events for non-init namespacesJiri Pirko
Since now, the table with same id in multiple netnamespaces were squashed to a single virtual router. That is not only incorrect, it also causes error messages when trying to use RALUE register to do double remove of FIB entries, like this one: mlxsw_spectrum 0000:03:00.0: EMAD reg access failed (tid=facb831c00007b20,reg_id=8013(ralue),type=write,status=7(bad parameter)) Since we don't allow ports to change namespaces (NETIF_F_NETNS_LOCAL), and the infrastructure is not yet prepared to handle netnamespaces, just ignore FIB notification events for non-init namespaces. That is clear to do since we don't need to offload them.

2016-11-10mlxsw: spectrum_router: Fix handling of neighbour structureJiri Pirko
__neigh_create function works in a different way than assumed. It passes "n" as a parameter to ndo_neigh_construct. But this "n" might be destroyed right away before __neigh_create() returns in case there is already another neighbour struct in the hashtable with the same dev and primary key. That is not expected by mlxsw_sp_router_neigh_construct() and the stored "n" points to freed memory, eventually leading to crash. Fix this by doing tight 1:1 coupling between neighbour struct and internal driver neigh_entry. That allows to narrow down the key in internal driver hashtable to do lookups by "n" only.

pm_rst, aclk_rst, pclk_rst was controlled by ROM code so the software wasn't needed to control it again in theory. But it didn't work properly, so we do need to do it again and add enough delay between the assert of pm_rst and the deassert of pm_rst. The Soc intergrated with this controller, rk3399, is still under MP test internally, so the backward compatibility won't be a big deal.

2016-11-10xprtrdma: Fix DMAR failure in frwr_op_map() after reconnectChuck Lever
When a LOCALINV WR is flushed, the frmr is marked STALE, then frwr_op_unmap_sync DMA-unmaps the frmr's SGL. These STALE frmrs are then recovered when frwr_op_map hunts for an INVALID frmr to use. All other cases that need frmr recovery leave that SGL DMA-mapped. The FRMR recovery path unconditionally DMA-unmaps the frmr's SGL. To avoid DMA unmapping the SGL twice for flushed LOCAL_INV WRs, alter the recovery logic (rather than the hot frwr_op_unmap_sync path) to distinguish among these cases. This solution also takes care of the case where multiple LOCAL_INV WRs are issued for the same rpcrdma_req, some complete successfully, but some are flushed.
