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.

     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
     that the init/suspend/resume ordering is correct.

   - A new clocksource/event driver for Microchip PIT64

   - Suspend/resume support for the Hyper-V clocksource

 "A set of watchdog/softlockup related improvements:

   - Enforce that the watchdog timestamp is always valid on boot. The

     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.

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"
