Linus Torvalds 4fd9435641 Updates for timers, timekeeping and related functionality: ... - Core: - Make the takeover of a hrtimer based broadcast timer reliable during CPU hot-unplug. The current implementation suffers from a race which can lead to broadcast timer starvation in the worst case. - VDSO related cleanups and simplifications - Small cleanups and enhancements all over the place - PTP: - Replace the architecture specific base clock to clocksource, e.g. ART to TSC, conversion function with generic functionality to avoid exposing such internals to drivers and convert all existing drivers over. This also allows to provide functionality which converts the other way round in the core code based on the same parameter set. - Provide a function to convert CLOCK_REALTIME to the base clock to support the upcoming PPS output driver on Intel platforms. - Drivers: - A set of Device Tree bindings for new hardware - Cleanups and enhancements all over the place -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmaUOM0THHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYofolD/9kK+aYdDj1gCFuZXZ2wTgMMxFmf/91 0UcsGRuBJiIXs3H3iizQ0Mb0cdTW6qZJoBp0jPlvUSm0BEKdEgE1uRX2RuAPZ/Gq 4/54ZJVopKSgAqeJFmqQubRVSv2XdMRAAJT0o1oUG3jZ0c6u8vqArIh5ZCnu13l/ tsNOeYLYzQFyA30eHSJ/KjQ2zHwAhJnl5a/b7pdAvxmlN37bGgKEpglv+9zwFiDB K/kWbpb/oED9WOmoQy5QYi8iSvLQHEhFGrqzXV3fegu/B/mBBf/bpsisVx7Z1m2R nzxNqg86RdMjNR6giwBETZjm7YxM+gKb9nCBNILjbjWZFC4tyrBkLGJ+KniTRNyZ M5R4X1oP/14h00qXmCgIEFWysXaJRewYI+TIm8R2rLXrR6Tf3c4oL6fHQJxy3X52 7A+4Z/vOk/KX6PxYmLC+xQDukhFh2nirVYsP1oNM9yC9zR/wkBBXTTmUSAI+8m8l KphniSPS2HMSBI6TtgOT8SKY7lRUZTnafBZq7wRXCv0Zz8AXoofgQDmBkXC99BkB MjLvRotJVJvY9a8LtA7htjDg/jiEMa0wHRNAGNSbflKoAKrJzoE5WbFxFZKbq3vZ o8cEYRMAIP+X+qn+oymT45XXXQlifZiccJdAi9FqDTvplEib2jmTmH6Ae5Khkr4l Lbzh/nSKVN7lOg== =8GjP -----END PGP SIGNATURE----- Merge tag 'timers-core-2024-07-14' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull timer updates from Thomas Gleixner: "Updates for timers, timekeeping and related functionality: Core: - Make the takeover of a hrtimer based broadcast timer reliable during CPU hot-unplug.
