When this file was split in commit 5d945cbc ("drm/amd/display: Create a file dedicated to planes") this chunk seemed to get dropped. Linus noticed on this rx580 and I've reproduced on FIJI which makes sense as these are pre-modifier GPUs. With this applied, I get gdm back.

Pull iomap updates from Darrick Wong: "The most notable change in this first batch is that we no longer schedule pages beyond i_size for writeback, preferring instead to let truncate deal with those pages. Next week, there may be a second pull request to remove iomap_writepage from the other two filesystems (gfs2/zonefs) that use iomap for buffered IO. This follows in the same vein as the recent removal of writepage from XFS, since it hasn't been triggered in a few years; it does nothing during direct reclaim; and as far as the people who examined the patchset can tell, it's moving the codebase in the right direction. However, as it was a late addition to for-next, I'm holding off on that section for another week of testing to see if anyone can come up with a solid reason for holding off in the meantime. Summary: - Skip writeback for pages that are completely beyond EOF - Minor code cleanups" * tag 'iomap-5.20-merge-1' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: dax: set did_zero to true when zeroing successfully iomap: set did_zero to true when zeroing successfully iomap: skip pages past eof in iomap_do_writepage()

Pull btrfs updates from David Sterba: "This brings some long awaited changes, the send protocol bump, otherwise lots of small improvements and fixes. The main core part is reworking bio handling, cleaning up the submission and endio and improving error handling. There are some changes outside of btrfs adding helpers or updating API, listed at the end of the changelog. Features: - sysfs: - export chunk size, in debug mode add tunable for setting its size - show zoned among features (was only in debug mode) - show commit stats (number, last/max/total duration) - send protocol updated to 2 - new commands: - ability write larger data chunks than 64K - send raw compressed extents (uses the encoded data ioctls), ie. no decompression on send side, no compression needed on receive side if supported - send 'otime' (inode creation time) among other timestamps - send file attributes (a.k.a file flags and xflags) - this is first version bump, backward compatibility on send and receive side is provided - there are still some known and wanted commands that will be implemented in the near future, another version bump will be needed, however we want to minimize that to avoid causing usability issues - print checksum type and implementation at mount time - don't print some messages at mount (mentioned as people asked about it), we want to print messages namely for new features so let's make some space for that - big metadata - this has been supported for a long time and is not a feature that's worth mentioning - skinny metadata - same reason, set by default by mkfs Performance improvements: - reduced amount of reserved metadata for delayed items - when inserted items can be batched into one leaf - when deleting batched directory index items - when deleting delayed items used for deletion - overall improved count of files/sec, decreased subvolume lock contention - metadata item access bounds checker micro-optimized, with a few percent of improved runtime for metadata-heavy operations - increase direct io limit for read to 256 sectors, improved throughput by 3x on sample workload Notable fixes: - raid56 - reduce parity writes, skip sectors of stripe when there are no data updates - restore reading from on-disk data instead of using stripe cache, this reduces chances to damage correct data due to RMW cycle - refuse to replay log with unknown incompat read-only feature bit set - zoned - fix page locking when COW fails in the middle of allocation - improved tracking of active zones, ZNS drives may limit the number and there are ENOSPC errors due to that limit and not actual lack of space - adjust maximum extent size for zone append so it does not cause late ENOSPC due to underreservation - mirror reading error messages show the mirror number - don't fallback to buffered IO for NOWAIT direct IO writes, we don't have the NOWAIT semantics for buffered io yet - send, fix sending link commands for existing file paths when there are deleted and created hardlinks for same files - repair all mirrors for profiles with more than 1 copy (raid1c34) - fix repair of compressed extents, unify where error detection and repair happen Core changes: - bio completion cleanups - don't double defer compression bios - simplify endio workqueues - add more data to btrfs_bio to avoid allocation for read requests - rework bio error handling so it's same what block layer does, the submission works and errors are consumed in endio -

Pull random number generator updates from Jason Donenfeld: "Though there's been a decent amount of RNG-related development during this last cycle, not all of it is coming through this tree, as this cycle saw a shift toward tackling early boot time seeding issues, which took place in other trees as well. Here's a summary of the various patches: - The CONFIG_ARCH_RANDOM .config option and the "nordrand" boot option have been removed, as they overlapped with the more widely supported and more sensible options, CONFIG_RANDOM_TRUST_CPU and "random.trust_cpu". This change allowed simplifying a bit of arch code. - x86's RDRAND boot time test has been made a bit more robust, with RDRAND disabled if it's clearly producing bogus results. This would be a tip.git commit, technically, but I took it through random.git to avoid a large merge conflict. - The RNG has long since mixed in a timestamp very early in boot, on the premise that a computer that does the same things, but does so starting at different points in wall time, could be made to still produce a different RNG state. Unfortunately, the clock isn't set early in boot on all systems, so now we mix in that timestamp when the time is actually set. - User Mode Linux now uses the host OS's getrandom() syscall to generate a bootloader RNG seed and later on treats getrandom() as the platform's RDRAND-like faculty. - The arch_get_random_{seed_,}_long() family of functions is now arch_get_random_{seed_,}_longs(), which enables certain platforms, such as s390, to exploit considerable performance advantages from requesting multiple CPU random numbers at once, while at the same time compiling down to the same code as before on platforms like x86. - A small cleanup changing a cmpxchg() into a try_cmpxchg(), from Uros. - A comment spelling fix" More info about other random number changes that come in through various architecture trees in the full commentary in the pull request: https://lore.kernel.org/all/20220731232428.2219258-1-Jason@zx2c4.com/ * tag 'random-6.0-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random: random: correct spelling of "overwrites" random: handle archrandom with multiple longs um: seed rng using host OS rng random: use try_cmpxchg in _credit_init_bits timekeeping: contribute wall clock to rng on time change x86/rdrand: Remove "nordrand" flag in favor of "random.trust_cpu" random: remove CONFIG_ARCH_RANDOM

The commit a1a2b712 ("of/platform: Drop static setup of IRQ resource from DT core") stopped IRQ resources being available as platform resources. This broke the sanity check for the expected number of resources in the Marvell SATA driver which expected two resources, the IO memory and the interrupt. Change the sanity check to only expect the IO memory.

Pull integrity updates from Mimi Zohar: "Aside from the one EVM cleanup patch, all the other changes are kexec related. On different architectures different keyrings are used to verify the kexec'ed kernel image signature. Here are a number of preparatory cleanup patches and the patches themselves for making the keyrings - builtin_trusted_keyring, .machine, .secondary_trusted_keyring, and .platform - consistent across the different architectures" * tag 'integrity-v6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity: kexec, KEYS, s390: Make use of built-in and secondary keyring for signature verification arm64: kexec_file: use more system keyrings to verify kernel image signature kexec, KEYS: make the code in bzImage64_verify_sig generic kexec: clean up arch_kexec_kernel_verify_sig kexec: drop weak attribute from functions kexec_file: drop weak attribute from functions evm: Use IS_ENABLED to initialize .enabled

Pull SafeSetID updates from Micah Morton: "This contains one commit that touches common kernel code, one that adds functionality internal to the SafeSetID LSM code, and a few other commits that only modify the SafeSetID LSM selftest. The commit that touches common kernel code simply adds an LSM hook in the setgroups() syscall that mirrors what is done for the existing LSM hooks in the setuid() and setgid() syscalls. This commit combined with the SafeSetID-specific one allow the LSM to filter setgroups() calls according to configured rule sets in the same way that is already done for setuid() and setgid()" * tag 'safesetid-6.0' of https://github.com/micah-morton/linux: LSM: SafeSetID: add setgroups() testing to selftest LSM: SafeSetID: Add setgroups() security policy handling security: Add LSM hook to setgroups() syscall LSM: SafeSetID: add GID testing to selftest LSM: SafeSetID: selftest cleanup and prepare for GIDs LSM: SafeSetID: fix userns bug in selftest
