22380b6 Lee Jones 19 August 2020, 08:16:50 UTC mfd: mfd-core: Ensure disabled devices are ignored without error Commit e49aa9a9bd22 ("mfd: core: Make a best effort attempt to match devices with the correct of_nodes") changed the semantics for disabled devices in mfd_add_device(). Instead of silently ignoring a disabled child device, an error was returned. On receipt of the error mfd_add_devices() the precedes to remove *all* child devices and returns an all-failed error to the caller, which will inevitably fail the parent device as well. This patch reverts back to the old semantics and ignores child devices which are disabled in Device Tree.

168f09c Nicholas Kazlauskas 19 August 2020, 17:37:54 UTC drm/amd/display: Reject overlay plane configurations in multi-display scenarios [Why] These aren't stable on some platform configurations when driving multiple displays, especially on higher resolution. In particular the delay in asserting p-state and validating from x86 outweights any power or performance benefit from the hardware composition. Under some configurations this will manifest itself as extreme stutter or unresponsiveness especially when combined with cursor movement. [How] Disable these for now. Exposing overlays to userspace doesn't guarantee that they'll be able to use them in any and all configurations and it's part of the DRM contract to have userspace gracefully handle validation failures when they occur. Valdiation occurs as part of DC and this in particular affects RV, so disable this in dcn10_global_validation.

69d9f42 Alexander Monakov 04 August 2020, 20:13:13 UTC drm/amd/display: use correct scale for actual_brightness Documentation for sysfs backlight level interface requires that values in both 'brightness' and 'actual_brightness' files are interpreted to be in range from 0 to the value given in the 'max_brightness' file. With amdgpu, max_brightness gives 255, and values written by the user into 'brightness' are internally rescaled to a wider range. However, reading from 'actual_brightness' gives the raw register value without inverse rescaling. This causes issues for various userspace tools such as PowerTop and systemd that expect the value to be in the correct range. Introduce a helper to retrieve internal backlight range. Use it to reimplement 'convert_brightness' as 'convert_brightness_from_user' and introduce 'convert_brightness_to_user'.

To avoid this, use BIT_ULL, which will be an unsigned long long. This matches the size of the features field throughout this driver, which is u64 so there should be no functional change.

ebce3eb Jeff Layton 18 August 2020, 12:03:48 UTC ceph: fix inode number handling on arches with 32-bit ino_t Tuan and Ulrich mentioned that they were hitting a problem on s390x, which has a 32-bit ino_t value, even though it's a 64-bit arch (for historical reasons). I think the current handling of inode numbers in the ceph driver is wrong. It tries to use 32-bit inode numbers on 32-bit arches, but that's actually not a problem. 32-bit arches can deal with 64-bit inode numbers just fine when userland code is compiled with LFS support (the common case these days). What we really want to do is just use 64-bit numbers everywhere, unless someone has mounted with the ino32 mount option. In that case, we want to ensure that we hash the inode number down to something that will fit in 32 bits before presenting the value to userland. Add new helper functions that do this, and only do the conversion before presenting these values to userland in getattr and readdir. The inode table hashvalue is changed to just cast the inode number to unsigned long, as low-order bits are the most likely to vary anyway. While it's not strictly required, we do want to put something in inode->i_ino. Instead of basing it on BITS_PER_LONG, however, base it on the size of the ino_t type. NOTE: This is a user-visible change on 32-bit arches: 1/ inode numbers will be seen to have changed between kernel versions. 32-bit arches will see large inode numbers now instead of the hashed ones they saw before. 2/ any really old software not built with LFS support may start failing stat() calls with -EOVERFLOW on inode numbers >2^32. Nothing much we can do about these, but hopefully the intersection of people running such code on ceph will be very small. The workaround for both problems is to mount with "-o ino32".

50248a3 Lucas Stach 24 August 2020, 10:55:37 UTC drm/etnaviv: always start/stop scheduler in timeout processing The drm scheduler currently expects that the stop/start sequence is always executed in the timeout handling, as the job at the head of the hardware execution list is always removed from the ring mirror before the driver function is called and only inserted back into the list when starting the scheduler. This adds some unnecessary overhead if the timeout handler determines that the GPU is still executing jobs normally and just wished to extend the timeout, but a better solution requires a major rearchitecture of the scheduler, which is not applicable as a fix.

2217b98 Max Filippov 08 August 2020, 18:37:13 UTC binfmt_flat: revert "binfmt_flat: don't offset the data start" binfmt_flat loader uses the gap between text and data to store data segment pointers for the libraries. Even in the absence of shared libraries it stores at least one pointer to the executable's own data segment. Text and data can go back to back in the flat binary image and without offsetting data segment last few instructions in the text segment may get corrupted by the data segment pointer. Fix it by reverting commit a2357223c50a ("binfmt_flat: don't offset the data start").

RDPID depends on MSR_TSX_AUX. KVM has an optmization to avoid expensive MRS read/writes on VMENTER/EXIT. It caches the MSR values and restores them either when leaving the run loop, on preemption or when going out to user space. MSR_TSX_AUX is part of that lazy MSR set, so after writing the guest value and before the lazy restore any exception using the paranoid entry will read the guest value and use it as CPU number to retrieve the GSBASE value for the current CPU when FSGSBASE is enabled. As RDPID is only used in that particular entry path, there is no reason to burden VMENTER/EXIT with two extra MSR writes. Remove the RDPID optimization, which is not even backed by numbers from the paranoid entry path instead" * tag 'x86-urgent-2020-08-23' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/entry/64: Do not use RDPID in paranoid entry to accomodate KVM 23 August 2020, 18:21:16 UTC

However, this check list isn't completely safe when deletions can happen concurrently. To sidestep the issue, make sure that a struct file placed on the check list sees its f_count increased, ensuring that a concurrent deletion won't result in the file disapearing from under our feet.
