Core: - Yet another round of improvements to make the clocksource watchdog more robust: - Relax the clocksource-watchdog skew criteria to match the NTP criteria. - Temporarily skip the watchdog when high memory latencies are detected which can lead to false-positives. - Provide an option to enable TSC skew detection even on systems where TSC is marked as reliable. Sigh! - Initialize the restart block in the nanosleep syscalls to be directed to the no restart function instead of doing a partial setup on entry. This prevents an erroneous restart_syscall() invocation from corrupting user space data. While such a situation is clearly a user space bug, preventing this is a correctness issue and caters to the least suprise principle. - Ignore the hrtimer slack for realtime tasks in schedule_hrtimeout() to align it with the nanosleep semantics. Drivers: - The obligatory new driver bindings for Mediatek, Rockchip and RISC-V variants. - Add support for the C3STOP misfeature to the RISC-V timer to handle the case where the timer stops in deeper idle state. - Set up a static key in the RISC-V timer correctly before first use. - The usual small improvements and fixes all over the place -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmPzV+cTHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoYlDEACMrjN2F6qeiOW94t4nQ3qP1M9AMSgO OihC04XuM14/3tEviu/cUOd60wYcUQ/kfI5C+IL35ezeP2w9lnuKqeFpG7aDOa33 5F3isDPamJdXZEZs44CW15brR6dqDlEi5acKee/TtFV9mN6xNhzxM64IaFqecPmW P+BTwunB8xwquY8RzsHXor/GOGb6mqWQIPoHEPnywTDe/xQYWt0Exzi7ch6HQr5Z ZzHG6X4h6UTNimjay6L4qsRQWILmPIg4Z5IlycWMQ8qDFM0lbnIJqkG4JwceolI6 aRQyLe3NQFcPYgq3ue+SNm4RckYn4NbAa1zFm0d5VDgKp4xW1sxvtkxOJuxjaOw2 /rLkHkmyuVvCeTMAySfxrwnszAoM505CHC6CEYc1xELbeCkROFUaymtVyNFnnTru V/Jt/T2Gyx6tOrafX7u+djUjv9figddRpNbskVZvEi3Ztq4MQ069nK3oSUqtP5vO INApNg4lq6s8aGqVE+Kp9+CKwGqZqI4MdxQMNMAmCRLPon6apActVawbj18qO/wS qblQ0cbF8a16itlQ3V68qmhcPh6EZOuq8II4etNq6U0ulV9712WfMbat3z53LG94 QNkAmZ3/wui93I+Q2NPxhf5ybJFQZhR0SOtVO6xIdTgOntkODwzzGu9UapfD8mLb k5BpWnH8CoUgiw== =I67j -----END PGP SIGNATURE----- Merge tag 'timers-core-2023-02-20' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull timer updates from Thomas Gleixner: "Updates for timekeeping, timers and clockevent/source drivers: Core: - Yet another round of improvements to make the clocksource watchdog more robust: - Relax the clocksource-watchdog skew criteria to match the NTP criteria. - Temporarily skip the watchdog when high memory latencies are detected which can lead to false-positives. - Provide an option to enable TSC skew detection even on systems where TSC is marked as reliable.
