We need the bits of _TIF_WORK_MASK to be contiguous in order to to use this as an immediate argument to an AND instruction in entry.S. We happened to change these bits in commits: b5a5a01d ("arm64: uaccess: remove addr_limit_user_check()") 192caabd ("arm64: add support for TIF_NOTIFY_SIGNAL") which each worked in isolation, but the merge resolution in commit: 005b2a9d ("Merge tag 'tif-task_work.arch-2020-12-14' of git://git.kernel.dk/linux-block") happened to make the bits non-contiguous. Fix this by moving TIF_NOTIFY_SIGNAL to be bit 6, which is contiguous with the rest of _TIF_WORK_MASK. Otherwise, we'll get a build-time failure as below: arch/arm64/kernel/entry.S: Assembler messages: arch/arm64/kernel/entry.S:733: Error: immediate out of range at operand 3 -- `and x2,x19,#((1<<1)|(1<<0)|(1<<2)|(1<<3)|(1<<4)|(1<<5)|(1<<7))' scripts/Makefile.build:360: recipe for target 'arch/arm64/kernel/entry.o' failed Fixes: 005b2a9d ("Merge tag 'tif-task_work.arch-2020-12-14' of git://git.kernel.dk/linux-block") Signed-off-by:

Pull IOMMU updates from Will Deacon: "There's a good mixture of improvements to the core code and driver changes across the board. One thing worth pointing out is that this includes a quirk to work around behaviour in the i915 driver (see 65f746e8 ("iommu: Add quirk for Intel graphic devices in map_sg")), which otherwise interacts badly with the conversion of the intel IOMMU driver over to the DMA-IOMMU APU but has being fixed properly in the DRM tree. We'll revert the quirk later this cycle once we've confirmed that things don't fall apart without it.

Pull TIF_NOTIFY_SIGNAL updates from Jens Axboe: "This sits on top of of the core entry/exit and x86 entry branch from the tip tree, which contains the generic and x86 parts of this work. Here we convert the rest of the archs to support TIF_NOTIFY_SIGNAL. With that done, we can get rid of JOBCTL_TASK_WORK from task_work and signal.c, and also remove a deadlock work-around in io_uring around knowing that signal based task_work waking is invoked with the sighand wait queue head lock. The motivation for this work is to decouple signal notify based task_work, of which io_uring is a heavy user of, from sighand. The sighand lock becomes a huge contention point, particularly for threaded workloads where it's shared between threads. Even outside of threaded applications it's slower than it needs to be. Roman Gershman <romger@amazon.com> reported that his networked workload dropped from 1.6M QPS at 80% CPU to 1.0M QPS at 100% CPU after io_uring was changed to use TIF_NOTIFY_SIGNAL. The time was all spent hammering on the sighand lock, showing 57% of the CPU time there [1]. There are further cleanups possible on top of this. One example is TIF_PATCH_PENDING, where a patch already exists to use TIF_NOTIFY_SIGNAL instead. Hopefully this will also lead to more consolidation, but the work stands on its own as well" [1] https://github.com/axboe/liburing/issues/215 * tag 'tif-task_work.arch-2020-12-14' of git://git.kernel.dk/linux-block: (28 commits) io_uring: remove 'twa_signal_ok' deadlock work-around kernel: remove checking for TIF_NOTIFY_SIGNAL signal: kill JOBCTL_TASK_WORK io_uring: JOBCTL_TASK_WORK is no longer used by task_work task_work: remove legacy TWA_SIGNAL path sparc: add support for TIF_NOTIFY_SIGNAL riscv: add support for TIF_NOTIFY_SIGNAL nds32: add support for TIF_NOTIFY_SIGNAL ia64: add support for TIF_NOTIFY_SIGNAL h8300: add support for TIF_NOTIFY_SIGNAL c6x: add support for TIF_NOTIFY_SIGNAL alpha: add support for TIF_NOTIFY_SIGNAL xtensa: add support for TIF_NOTIFY_SIGNAL arm: add support for TIF_NOTIFY_SIGNAL microblaze: add support for TIF_NOTIFY_SIGNAL hexagon: add support for TIF_NOTIFY_SIGNAL csky: add support for TIF_NOTIFY_SIGNAL openrisc: add support for TIF_NOTIFY_SIGNAL sh: add support for TIF_NOTIFY_SIGNAL um: add support for TIF_NOTIFY_SIGNAL ...

Pull integrity subsystem updates from Mimi Zohar: "Just three patches here. Other integrity changes are being upstreamed via EFI (defines a common EFI secure and trusted boot IMA policy) and BPF LSM (exporting the IMA file cache hash info based on inode). The three patches included here: - bug fix: fail calculating the file hash, when a file not opened for read and the attempt to re-open it for read fails. - defer processing the "ima_appraise" boot command line option to avoid enabling different modes (e.g. fix, log) to when the secure boot flag is available on arm. - defines "ima-buf" as the default IMA buffer measurement template in preparation for the builtin integrity "critical data" policy" * tag 'integrity-v5.11' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity: ima: Don't modify file descriptor mode on the fly ima: select ima-buf template for buffer measurement ima: defer arch_ima_get_secureboot() call to IMA init time

Pull selinux updates from Paul Moore: "While we have a small number of SELinux patches for v5.11, there are a few changes worth highlighting: - Change the LSM network hooks to pass flowi_common structs instead of the parent flowi struct as the LSMs do not currently need the full flowi struct and they do not have enough information to use it safely (missing information on the address family). This patch was discussed both with Herbert Xu (representing team netdev) and James Morris (representing team LSMs-other-than-SELinux). - Fix how we handle errors in inode_doinit_with_dentry() so that we attempt to properly label the inode on following lookups instead of continuing to treat it as unlabeled. - Tweak the kernel logic around allowx, auditallowx, and dontauditx SELinux policy statements such that the auditx/dontauditx are effective even without the allowx statement.

Pull audit updates from Paul Moore: "A small set of audit patches for v5.11 with four patches in total and only one of any real significance. Richard's patch to trigger accompanying records causes the kernel to emit additional related records when an audit event occurs; helping provide some much needed context to events in the audit log.

There was only one user left for the ARCH_USES_GETTIMEOFFSET variant of clocksource implementations, the ARM EBSA110 platform. Rather than changing to use modern timekeeping, we remove the platform entirely as Russell no longer uses his machine and nobody else seems to have one any more. The conditional code for using arch_gettimeoffset() is removed as a result. For CONFIG_GENERIC_CLOCKEVENTS, there are still a couple of platforms not using clockevent drivers: parisc, ia64, most of m68k, and one Arm platform. These all do timer ticks slighly differently, and this gets cleaned up to the point they at least all call the same helper function.
