The config switch exists, but architecture code still exposes the legacy functionality even disabled. Clean this up by adding the missing guards and validating at build time that the VDSO is legacy free if disabled. - Consolidate the VDSO related config options in core and drivers, which removes some non-sensical dependencies and quite an amount of #ifdeffery. - Clean up the PAGE_SIZE definition maze * tag 'timers-vdso-2026-08-17' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (30 commits) random: vDSO: Drop custom PAGE_SIZE definitions LoongArch: Remove CONFIG_GENERIC_GETTIMEOFDAY ifdeffery clocksource/drivers/timer-riscv: Remove CONFIG_GENERIC_GETTIMEOFDAY ifdeffery clocksource/drivers/arm_arch_timer: Remove CONFIG_GENERIC_GETTIMEOFDAY ifdeffery clocksource/drivers/mips-gic-timer: Remove CONFIG_GENERIC_GETTIMEOFDAY ifdeffery MIPS: csrc-r4k: Remove CONFIG_GENERIC_GETTIMEOFDAY ifdeffery vDSO: Make clockmode constants available without CONFIG_GENERIC_GETTIMEOFDAY kbuild: Support generated asm-headers in subdirectories vdso: Rename HAVE_GENERIC_VDSO to VDSO_DATASTORE vdso: Drop HAVE_GENERIC_VDSO from architecture kconfig files vdso: Automatically select HAVE_GENERIC_VDSO if necessary MIPS: vdso: Stop using CONFIG_HAVE_GENERIC_VDSO vdso: Remove the dependency on HAVE_GENERIC_VDSO from ARCH_HAS_VDSO_ARCH_DATA futex: Remove dependency on HAVE_GENERIC_VDSO from FUTEX_ROBUST_UNLOCK vdso/gettimeofday: Verify COMPAT_32BIT_TIME interactions sparc: vdso: Respect COMPAT_32BIT_TIME MIPS: VDSO: Respect COMPAT_32BIT_TIME powerpc/vdso: Respect COMPAT_32BIT_TIME ARM: VDSO: Respect COMPAT_32BIT_TIME arm64: vdso32: Respect COMPAT_32BIT_TIME ... 2026-08-18T23:23:56+00:00 Linus Torvalds torvalds@linux-foundation.org 2026-08-18T23:23:56+00:00 urn:sha1:3b4128b9f374b4219eb716f4ad8a307bc7eb3d84 Pull timer and timekeeping core updates from Thomas Gleixner: - Fix a subtly inconsistency in the timekeeping code, which fails to account for the monotonicity adjustment in ntp_error. For small changes of the clocksource multiplicator (+/-1) which are typically used by the NTP PLL this is hard to observe. But for larger adjustments, e.g. caused by a direct frequency setting through adjtimex() the one-time uncompensated offset is significant. Cure this by adjusting ntp_error with the resulting offset so that the discrepancy is smoothed away over time - Make tick length calculations correct in NTP. The timekeeping core takes the quantisation of the clocksource into account when calculating the tick length to compensate for the deviation of the nominal NTP_INTERVAL_LENGTH. While timekeeping gets this right, NTP is not aware of that, which means it operates on the nominal value and not on the actual value which is determined by the clock source frequency. The rounding of a coarse clocksource like the ACPI PM timer results in a +127 PPM deviation. Cure this by exposing the deviation to the NTP code so that it can operate on the same data as the timekeeping core. This is purely kernel internal. User space still sees the nominal tick lenght via adjtimex(). - The accuracy of the NTP adjustments is fairly approximate as the code assumes that the invocations are precisely in NTP interval frequency ticks and the final adjustment can over and under-run. Cure this by adjusting ntp_error by the intended skew on each tick to achieve the desired rate. - Handle the two competing skews of time offset and time adjustment correctly by calculating the conflict portion between the skews and adjusting both accordingly. - A set of updates and improvements for the selftests - The usual small fixes and improvements all over the place * tag 'timers-core-2026-08-17' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (58 commits) selftests: timers: nsleep-lat: Check all calls to clock_nanosleep() and clock_gettime() selftests: timers: nsleep-lat: Reuse kselftest error numbers selftests: timers: nsleep-lat: Explicitly list the tested clocks selftests: timers: nsleep-lat: Use NSEC_PER_MSEC define for unreasonable latency selftests: timers: nanosleep: Report each test separately selftests: timers: nanosleep: Explicitly handle timer_delete() failure selftests: timers: nanosleep: Move all single clock tests out of the loop in main() selftests: timers: nanosleep: Reuse kselftest error numbers selftests: timers: nanosleep: Explicitly list the tested clocks selftests: timers: nanosleep: Drop output alignment selftests: timers: Use clock_name() and constants from clock-helpers.h selftests: Add clock-helpers.h timer_list: Use ktime_t over nanoseconds timer_list: Use standard 'long long' format placeholders hrtimer: Add a lockdep assertion to hrtimer_update_base() timekeeping: Use u32 for clock_was_set_seq timekeeping: Rename clockid_aux_valid() to clockid_is_aux_clock() hrtimer: Account nr_retries on recovered interrupt retries timers/itimer: Zero-init old itimerval before copy to userspace nohz: Replace dead select with choice default ... 2026-08-18T22:58:29+00:00 Linus Torvalds torvalds@linux-foundation.org 2026-08-18T22:58:29+00:00 urn:sha1:030c9f813b8e48d2b066983c94cf6294968f9496 Pull treewide timer related cleanups from Thomas Gleixner: - Remove the leftover CLOCK_TICK_RATE which has been scheduled for removal more than a decade ago along with some now empty asm/timex.h files. - Consolidate delay timer calibration The construct of having a define in a header requires that architectures provided asm/timex.h for no reason. Also the function name for reading the delay timer is confusing at best. Use a config switch to enable that functionality and rename the function to delay_read_timer() to make the purpose clear. This removes some more now empty asm/timex.h files as well. * tag 'timers-cleanups-2026-08-17' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: calibrate: Rework delay timer calibration treewide: Remove CLOCK_TICK_RATE x86: Use PIT_TICK_RATE instead of CLOCK_TICK_RATE
