2017-01-18drm/i915: Ignore bogus plane coordinates on SKL when the plane is not visibleVille Syrjälä
When the plane is invisible we may have all sorts of bogus stuff in the coordinates, which we must ignore or else we might fail the plane update. This started to happen on SKL when I moved the plane offset computation to happen in the check phase. Previously we happily ignored it all since we never called the update_plane hook with an invisible plane.

2017-01-18drm/i915: Remove WaDisableLSQCROPERFforOCL KBL workaround.Francisco Jerez
The WaDisableLSQCROPERFforOCL workaround has the side effect of disabling an L3SQ optimization that has huge performance implications and is unlikely to be necessary for the correct functioning of usual graphic workloads. Userspace is free to re-enable the workaround on demand, and is generally in a better position to determine whether the workaround is necessary than the DRM is (e.g. only during the execution of compute kernels that rely on both L3 fences and HDC R/W requests). The same workaround seems to apply to BDW (at least to production stepping G1) and SKL as well (the internal workaround database claims that it does for all steppings, while the BSpec workaround table only mentions pre-production steppings), but the DRM doesn't do anything beyond whitelisting the L3SQCREG4 register so userspace can enable it when it sees fit. Do the same on KBL platforms. Improves performance of the GFXBench4 gl_manhattan31 benchmark by 60%, and gl_4 (AKA car chase) by 14% on a KBL GT2 running Mesa master -- This is followed by a regression of 35% and 10% respectively for the same benchmarks and platform caused by my recent patch series switching userspace to use the dataport constant cache instead of the sampler to implement uniform pull constant loads, which caused us to hit more heavily the L3 cache (and on platforms other than KBL had the opposite effect of improving performance of the same two benchmarks). The overall effect on KBL of this change combined with the recent userspace change is respectively 4.6% and 2.6%. SynMark2 OglShMapPcf was affected by the constant cache changes (though it improved as it did on other platforms rather than regressing), but is not significantly affected by this patch (with statistical significance of 5% and sample size 20). v2: Drop some more code to avoid unused variable warning.

The priv->device pointer for c_can_pci is never set, but it is used without a NULL check in c_can_start(). Setting it in c_can_pci_probe() like c_can_plat_probe() prevents c_can_pci.ko from crashing, with and without CONFIG_PM. This might also cause the pm_runtime_*() functions in c_can.c to actually be executed for c_can_pci devices - they are the only other place where priv->device is used, but they all contain a null check.

mpt3sas has a firmware failure where it can only handle one pass through ATA command at a time. If another comes in, contrary to the SAT standard, it will hang until the first one completes (causing long commands like secure erase to timeout). The original fix was to block the device when an ATA command came in, but this caused a regression with commit 669f044170d8933c3d66d231b69ea97cb8447338 Author: Bart Van Assche <bart.vanassche@sandisk.com> Date: Tue Nov 22 16:17:13 2016 -0800 scsi: srp_transport: Move queuecommand() wait code to SCSI core So fix the original fix of the secure erase timeout by properly returning SAM_STAT_BUSY like the SAT recommends.

2017-01-17stmmac: add missing of_node_putJulia Lawall
The function stmmac_dt_phy provides several possibilities for initializing plat->mdio_node, all of which have the effect of increasing the reference count of the assigned value. This field is not updated elsewhere, so the value is live until the end of the lifetime of plat (devm_allocated), just after the end of stmmac_remove_config_dt. Thus, add an of_node_put on plat->mdio_node in stmmac_remove_config_dt. It is possible that the field mdio_node is never initialized, but of_node_put is NULL-safe, so it is also safe to call of_node_put in that case.

This makes diagnosis of hw checksumming bugs really annoying. Fix from Hayes Wang. 3) VXLAN route lookup does not take the source and destination ports into account, which means IPSEC policies cannot be matched properly.

Fix from Basil Gunn. 10) Action GET operations in the packet scheduler can erroneously bump the reference count of the entry, making it unreleasable. Fix from Jamal Hadi Salim.

2017-01-17PCI/MSI: pci-xgene-msi: Fix CPU hotplug registration handlingMarc Zyngier
The conversion to the new hotplug state machine introduced a regression where a successful hotplug registration would be treated as an error, effectively disabling the MSI driver forever. Fix it by doing the proper check on the return value.

2017-01-17drm/vc4: Return -EINVAL on the overflow checks failing.Eric Anholt
By failing to set the errno, we'd continue on to trying to set up the RCL, and then oops on trying to dereference the tile_bo that binning validation should have set up.

2017-01-17drm/vc4: Fix an integer overflow in temporary allocation layout.Eric Anholt
We copy the unvalidated ioctl arguments from the user into kernel temporary memory to run the validation from, to avoid a race where the user updates the unvalidate contents in between validating them and copying them into the validated BO. However, in setting up the layout of the kernel side, we failed to check one of the additions (the roundup() for shader_rec_offset) against integer overflow, allowing a nearly MAX_UINT value of bin_cl_size to cause us to under-allocate the temporary space that we then copy_from_user into.
