      Pull irq updates from Thomas Gleixner:
       "The interrupt departement provides:
      
         - A mechanism to shield isolated tasks from managed interrupts:
      
           The affinity of managed interrupts is completely controlled by the
           kernel and user space has no influence on them. The reason is that
           the automatically assigned affinity correlates to the multi-queue
           CPU handling of block devices.
      
           If the generated affinity mask spaws both housekeeping and isolated
           CPUs the interrupt could be routed to an isolated CPU which would
           then be disturbed by I/O submitted by a housekeeping CPU.
      
           The new mechamism ensures that as long as one housekeeping CPU is
           online in the assigned affinity mask the interrupt is routed to a
           housekeeping CPU.
      
           If there is no online housekeeping CPU in the affinity mask, then
           the interrupt is routed to an isolated CPU to keep the device queue
           intact, but unless the isolated CPU submits I/O by itself these
           interrupts are not raised.
      
         - A small addon to the device tree irqdomain core code to avoid
           duplication in irq chip drivers

      Pull timer updates from Thomas Gleixner:
       "The timekeeping and timers departement provides:
      
         - Time namespace support:
      
           If a container migrates from one host to another then it expects
           that clocks based on MONOTONIC and BOOTTIME are not subject to
           disruption. Due to different boot time and non-suspended runtime
           these clocks can differ significantly on two hosts, in the worst
           case time goes backwards which is a violation of the POSIX
           requirements.
      
           The time namespace addresses this problem. It allows to set offsets
           for clock MONOTONIC and BOOTTIME once after creation and before
           tasks are associated with the namespace. These offsets are taken
           into account by timers and timekeeping including the VDSO.
      
           Offsets for wall clock based clocks (REALTIME/TAI) are not provided
           by this mechanism. While in theory possible, the overhead and code
           complexity would be immense and not justified by the esoteric
           potential use cases which were discussed at Plumbers '18.
      
           The overhead for tasks in the root namespace (ie where host time
           offsets = 0) is in the noise and great effort was made to ensure
           that especially in the VDSO. If time namespace is disabled in the
           kernel configuration the code is compiled out.
      
           Kudos to Andrei Vagin and Dmitry Sofanov who implemented this
           feature and kept on for more than a year addressing review
           comments, finding better solutions. A pleasant experience.
      
         - Overhaul of the alarmtimer device dependency handling to ensure

      Pull watchdog updates from Thomas Gleixner:
       "A set of watchdog/softlockup related improvements:
      
         - Enforce that the watchdog timestamp is always valid on boot. The
           original implementation caused a watchdog disabled gap of one
           second in the boot process due to truncation of the underlying
           sched clock.
      
           The sched clock is divided by 1e9 to convert nanoseconds to
           seconds. So for the first second of the boot process the result is
           0 which is at the same time the indicator to disable the watchdog.
      
           The trivial fix is to change the disabled indicator to ULONG_MAX.
      
         - Two cleanup patches removing unused and redundant code which got
           forgotten to be cleaned up in previous changes"

      Pull timer fixes from Thomas Gleixner:
       "Two fixes for the generic VDSO code which missed 5.5:
      
         - Make the update to the coarse timekeeper unconditional.
      
           This is required because the coarse timekeeper interfaces in the
           VDSO do not depend on a VDSO capable clocksource. If the system
           does not have a VDSO capable clocksource and the update is
           depending on the VDSO capable clocksource, the coarse VDSO
           interfaces would operate on stale data forever.
      
         - Invert the logic of __arch_update_vdso_data() to avoid further head
           scratching.
      
           Tripped over this several times while analyzing the update problem
           above"

      Pull SELinux update from Paul Moore:
       "This is one of the bigger SELinux pull requests in recent years with
        28 patches. Everything is passing our test suite and the highlights
        are below:
      
         - Mark CONFIG_SECURITY_SELINUX_DISABLE as deprecated. We're some time
           away from actually attempting to remove this in the kernel, but the
           only distro we know that still uses it (Fedora) is working on
           moving away from this so we want to at least let people know we are
           planning to remove it.
      
         - Reorder the SELinux hooks to help prevent bad things when SELinux
           is disabled at runtime. The proper fix is to remove the
           CONFIG_SECURITY_SELINUX_DISABLE functionality (see above) and just
           take care of it at boot time (e.g. "selinux=0").
      
         - Add SELinux controls for the kernel lockdown functionality,
           introducing a new SELinux class/permissions: "lockdown { integrity
           confidentiality }".
      
         - Add a SELinux control for move_mount(2) that reuses the "file {
           mounton }" permission.
      
         - Improvements to the SELinux security label data store lookup
           functions to speed up translations between our internal label
           representations and the visible string labels (both directions).
      
         - Revisit a previous fix related to SELinux inode auditing and
           permission caching and do it correctly this time.
      
         - Fix the SELinux access decision cache to cleanup properly on error.
           In some extreme cases this could limit the cache size and result in
           a decrease in performance.
      
         - Enable SELinux per-file labeling for binderfs.
      
         - The SELinux initialized and disabled flags were wrapped with
           accessors to ensure they are accessed correctly.
      
         - Mark several key SELinux structures with __randomize_layout.
      
         - Changes to the LSM build configuration to only build
           security/lsm_audit.c when needed.
      
         - Changes to the SELinux build configuration to only build the IB
           object cache when CONFIG_SECURITY_INFINIBAND is enabled.
      
         - Move a number of single-caller functions into their callers.
      
         - Documentation fixes (/selinux -> /sys/fs/selinux).
      
         - A handful of cleanup patches that aren't worth mentioning on their
           own, the individual descriptions have plenty of detail"

      Pull arm64 updates from Will Deacon:
       "The changes are a real mixed bag this time around.
      
        The only scary looking one from the diffstat is the uapi change to
        asm-generic/mman-common.h, but this has been acked by Arnd and is
        actually just adding a pair of comments in an attempt to prevent
        allocation of some PROT values which tend to get used for
        arch-specific purposes. We'll be using them for Branch Target
        Identification (a CFI-like hardening feature), which is currently
        under review on the mailing list.
      
        New architecture features:
      
         - Support for Armv8.5 E0PD, which benefits KASLR in the same way as
           KPTI but without the overhead. This allows KPTI to be disabled on
           CPUs that are not affected by Meltdown, even is KASLR is enabled.
      
         - Initial support for the Armv8.5 RNG instructions, which claim to
           provide access to a high bandwidth, cryptographically secure
           hardware random number generator. As well as exposing these to
           userspace, we also use them as part of the KASLR seed and to seed
           the crng once all CPUs have come online.
      
         - Advertise a bunch of new instructions to userspace, including
           support for Data Gathering Hint, Matrix Multiply and 16-bit
           floating point.
      
        Kexec:
      
         - Cleanups in preparation for relocating with the MMU enabled
      
         - Support for loading crash dump kernels with kexec_file_load()
      
        Perf and PMU drivers:
      
         - Cleanups and non-critical fixes for a couple of system PMU drivers
      
        FPU-less (aka broken) CPU support:
      
         - Considerable fixes to support CPUs without the FP/SIMD extensions,
           including their presence in heterogeneous systems. Good luck
           finding a 64-bit userspace that handles this.
      
        Modern assembly function annotations:
      
         - Start migrating our use of ENTRY() and ENDPROC() over to the
           new-fangled SYM_{CODE,FUNC}_{START,END} macros, which are intended
           to aid debuggers
      
        Kbuild:
      
         - Cleanup detection of LSE support in the assembler by introducing
           'as-instr'
      
         - Remove compressed Image files when building clean targets
      
        IP checksumming:
      
         - Implement optimised IPv4 checksumming routine when hardware offload
           is not in use. An IPv6 version is in the works, pending testing.
      
        Hardware errata:
      
         - Work around Cortex-A55 erratum #1530923
      
        Shadow call stack:
      
         - Work around some issues with Clang's integrated assembler not
           liking our perfectly reasonable assembly code
      
         - Avoid allocating the X18 register, so that it can be used to hold
           the shadow call stack pointer in future
      
        ACPI:
      
         - Fix ID count checking in IORT code. This may regress broken
           firmware that happened to work with the old implementation, in
           which case we'll have to revert it and try something else
      
         - Fix DAIF corruption on return from GHES handler with pseudo-NMIs
      
        Miscellaneous:
      
         - Whitelist some CPUs that are unaffected by Spectre-v2
      
         - Reduce frequency of ASID rollover when KPTI is compiled in but
           inactive
      
         - Reserve a couple of arch-specific PROT flags that are already used
           by Sparc and PowerPC and are planned for later use with BTI on
           arm64
      
         - Preparatory cleanup of our entry assembly code in preparation for
           moving more of it into C later on
      
         - Refactoring and cleanup"
