2020-04-07drm/nouveau/gr/gp107,gp108: implement workaround for HW hanging during initBen Skeggs
Certain boards with GP107/GP108 chipsets hang (often, but randomly) for unknown reasons during GR initialisation. The first tell-tale symptom of this issue is: nouveau 0000:01:00.0: bus: MMIO read of 00000000 FAULT at 409800 [ TIMEOUT ] appearing in dmesg, likely followed by many other failures being logged. Karol found this WAR for the issue a while back, but efforts to isolate the root cause and proper fix have not yielded success so far. I've modified the original patch to include a few more details, limit it to GP107/GP108 by default, and added a config option to override this choice.

2020-04-07drm/nouveau: workaround runpm fail by disabling PCI power management on ↵Karol Herbst
certain intel bridges Fixes the infamous 'runtime PM' bug many users are facing on Laptops with Nvidia Pascal GPUs by skipping said PCI power state changes on the GPU. Depending on the used kernel there might be messages like those in demsg: "nouveau 0000:01:00.0: Refused to change power state, currently in D3" "nouveau 0000:01:00.0: can't change power state from D3cold to D0 (config space inaccessible)" followed by backtraces of kernel crashes or timeouts within nouveau. It's still unkown why this issue exists, but this is a reliable workaround and solves a very annoying issue for user having to choose between a crashing kernel or higher power consumption of their Laptops.

2020-04-07drm/nouveau/svm: remove useless SVM range checkRalph Campbell
When nouveau processes GPU faults, it checks to see if the fault address falls within the "unmanaged" range which is reserved for fixed allocations instead of addresses chosen by the core mm code. If start is greater than or equal to svmm->unmanaged.limit, then limit will also be greater than svmm->unmanaged.limit which is greater than svmm->unmanaged.start and the start = max_t(u64, start, svmm->unmanaged.limit) will change nothing. Just remove the useless lines of code. Signed-off-by: Ralph Campbell <rcampbell@nvidia.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2020-04-07drm/nouveau/svm: check for SVM initialized before migratingRalph Campbell

2020-04-07drm/nouveau/svm: fix vma range check for migrationRalph Campbell
find_vma_intersection(mm, start, end) only guarantees that end is greater than or equal to vma->vm_start but doesn't guarantee that start is greater than or equal to vma->vm_start. The calculation for the intersecting range in nouveau_svmm_bind() isn't accounting for this and can call migrate_vma_setup() with a starting address less than vma->vm_start. This results in migrate_vma_setup() returning -EINVAL for the range instead of nouveau skipping that part of the range and migrating the rest.

2020-04-06net: dsa: bcm_sf2: Do not register slave MDIO bus with OFFlorian Fainelli
We were registering our slave MDIO bus with OF and doing so with assigning the newly created slave_mii_bus of_node to the master MDIO bus controller node. This is a bad thing to do for a number of reasons: - we are completely lying about the slave MII bus is arranged and yet we still want to control which MDIO devices it probes. It was attempted before to play tricks with the bus_mask to perform that: https://www.spinics.net/lists/netdev/msg429420.html but the approach was rightfully rejected - the device_node reference counting is messed up and we are effectively doing a double probe on the devices we already probed using the master, this messes up all resources reference counts (such as clocks) The proper fix for this as indicated by David in his reply to the thread above is to use a platform data style registration so as to control exactly which devices we probe: https://www.spinics.net/lists/netdev/msg430083.html By using mdiobus_register(), our slave_mii_bus->phy_mask value is used as intended, and all the PHY addresses that must be redirected towards our slave MDIO bus is happening while other addresses get redirected towards the master MDIO bus.

2020-04-06tun: Don't put_page() for all negative return values from XDP programWill Deacon
When an XDP program is installed, tun_build_skb() grabs a reference to the current page fragment page if the program returns XDP_REDIRECT or XDP_TX. However, since tun_xdp_act() passes through negative return values from the XDP program, it is possible to trigger the error path by mistake and accidentally drop a reference to the fragments page without taking one, leading to a spurious free. This is believed to be the cause of some KASAN use-after-free reports from syzbot [1], although without a reproducer it is not possible to confirm whether this patch fixes the problem. Ensure that we only drop a reference to the fragments page if the XDP transmit or redirect operations actually fail.

2020-04-05parisc: Replace setup_irq() by request_irq()afzal mohammed
request_irq() is preferred over setup_irq(). Invocations of setup_irq() occur after memory allocators are ready. Per tglx[1], setup_irq() existed in olden days when allocators were not ready by the time early interrupts were initialized. Hence replace setup_irq() by request_irq().

2020-04-05sysfs: remove redundant __compat_only_sysfs_link_entry_to_kobj fnLinus Torvalds
Commit 9255782f7061 ("sysfs: Wrap __compat_only_sysfs_link_entry_to_kobj function to change the symlink name") made this function a wrapper around a new non-underscored function, which is a bit odd. The normal naming convention is the other way around: the underscored function is the wrappee, and the non-underscored function is the wrapper. There's only one single user (well, two call-sites in that user) of the more limited double underscore version of this function, so just remove the oddly named wrapper entirely and just add the extra NULL argument to the user. I considered just doing that in the merge, but that tends to make history really hard to read.
