Merge branch 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull timer updates from Thomas Gleixner: "The timer departement delivers: - more year 2038 rework - a massive rework of the arm achitected timer - preparatory patches to allow NTP correction of clock event devices to avoid early expiry - the usual pile of fixes and enhancements all over the place" * 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (91 commits) timer/sysclt: Restrict timer migration sysctl values to 0 and 1 arm64/arch_timer: Mark errata handlers as __maybe_unused Clocksource/mips-gic: Remove redundant non devicetree init MIPS/Malta: Probe gic-timer via devicetree clocksource: Use GENMASK_ULL in definition of CLOCKSOURCE_MASK acpi/arm64: Add SBSA Generic Watchdog support in GTDT driver clocksource: arm_arch_timer: add GTDT support for memory-mapped timer acpi/arm64: Add memory-mapped timer support in GTDT driver clocksource: arm_arch_timer: simplify ACPI support code. acpi/arm64: Add GTDT table parse driver clocksource: arm_arch_timer: split MMIO timer probing. clocksource: arm_arch_timer: add structs to describe MMIO timer clocksource: arm_arch_timer: move arch_timer_needs_of_probing into DT init call clocksource: arm_arch_timer: refactor arch_timer_needs_probing clocksource: arm_arch_timer: split dt-only rate handling x86/uv/time: Set ->min_delta_ticks and ->max_delta_ticks unicore32/time: Set ->min_delta_ticks and ->max_delta_ticks um/time: Set ->min_delta_ticks and ->max_delta_ticks tile/time: Set ->min_delta_ticks and ->max_delta_ticks score/time: Set ->min_delta_ticks and ->max_delta_ticks ...
