git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip 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 - Conversion of the SiFive PLIC to hierarchical domains - The usual pile of new irq chip drivers: SiFive GPIO, Aspeed SCI, NXP INTMUX, Meson A1 GPIO - The first cut of support for the new ARM GICv4.1 - The usual pile of fixes and improvements in core and driver code" * tag 'irq-core-2020-01-28' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (33 commits) genirq, sched/isolation: Isolate from handling managed interrupts irqchip/gic-v4.1: Allow direct invalidation of VLPIs irqchip/gic-v4.1: Suppress per-VLPI doorbell irqchip/gic-v4.1: Add VPE INVALL callback irqchip/gic-v4.1: Add VPE eviction callback irqchip/gic-v4.1: Add VPE residency callback irqchip/gic-v4.1: Add mask/unmask doorbell callbacks irqchip/gic-v4.1: Plumb skeletal VPE irqchip irqchip/gic-v4.1: Implement the v4.1 flavour of VMOVP irqchip/gic-v4.1: Don't use the VPE proxy if RVPEID is set irqchip/gic-v4.1: Implement the v4.1 flavour of VMAPP irqchip/gic-v4.1: VPE table (aka GICR_VPROPBASER) allocation irqchip/gic-v3: Add GICv4.1 VPEID size discovery irqchip/gic-v3: Detect GICv4.1 supporting RVPEID irqchip/gic-v3-its: Fix get_vlpi_map() breakage with doorbells irqdomain: Fix a memory leak in irq_domain_push_irq() irqchip: Add NXP INTMUX interrupt multiplexer support dt-bindings: interrupt-controller: Add binding for NXP INTMUX interrupt multiplexer irqchip: Define EXYNOS_IRQ_COMBINER irqchip/meson-gpio: Add support for meson a1 SoCs ...

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip 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 - The usual pile of fixes, updates and improvements mostly in the driver code" * tag 'timers-core-2020-01-27' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (71 commits) alarmtimer: Make alarmtimer_get_rtcdev() a stub when CONFIG_RTC_CLASS=n alarmtimer: Use wakeup source from alarmtimer platform device alarmtimer: Make alarmtimer platform device child of RTC device alarmtimer: Update alarmtimer_get_rtcdev() docs to reflect reality hrtimer: Add missing sparse annotation for __run_timer() lib/vdso: Only read hrtimer_res when needed in __cvdso_clock_getres() MIPS: vdso: Define BUILD_VDSO32 when building a 32bit kernel clocksource/drivers/hyper-v: Set TSC clocksource as default w/ InvariantTSC clocksource/drivers/hyper-v: Untangle stimers and timesync from clocksources clocksource/drivers/timer-microchip-pit64b: Fix sparse warning clocksource/drivers/exynos_mct: Rename Exynos to lowercase clocksource/drivers/timer-ti-dm: Fix uninitialized pointer access clocksource/drivers/timer-ti-dm: Switch to platform_get_irq clocksource/drivers/timer-ti-dm: Convert to devm_platform_ioremap_resource clocksource/drivers/em_sti: Fix variable declaration in em_sti_probe clocksource/drivers/em_sti: Convert to devm_platform_ioremap_resource clocksource/drivers/bcm2835_timer: Fix memory leak of timer clocksource/drivers/cadence-ttc: Use ttc driver as platform driver clocksource/drivers/timer-microchip-pit64b: Add Microchip PIT64B support clocksource/drivers/hyper-v: Reserve PAGE_SIZE space for tsc page ...

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" * tag 'selinux-pr-20200127' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux: (28 commits) selinux: fix regression introduced by move_mount(2) syscall selinux: do not allocate ancillary buffer on first load selinux: remove redundant allocation and helper functions selinux: remove redundant selinux_nlmsg_perm selinux: fix wrong buffer types in policydb.c selinux: reorder hooks to make runtime disable less broken selinux: treat atomic flags more carefully selinux: make default_noexec read-only after init selinux: move ibpkeys code under CONFIG_SECURITY_INFINIBAND. selinux: remove redundant msg_msg_alloc_security Documentation,selinux: fix references to old selinuxfs mount point selinux: deprecate disabling SELinux and runtime selinux: allow per-file labelling for binderfs selinuxfs: use scnprintf to get real length for inode selinux: remove set but not used variable 'sidtab' selinux: ensure the policy has been loaded before reading the sidtab stats selinux: ensure we cleanup the internal AVC counters on error in avc_update() selinux: randomize layout of key structures selinux: clean up selinux_enabled/disabled/enforcing_boot selinux: remove unnecessary selinux cred request ...
