- Consolidate the VDSO datastore further and provide support for
mlock_all() and prefaulting.
- Provide 32-bit legacy time related functionality only if
CONFIG_COMPAT_32BIT_TIME is enabled. 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

Merge tag 'timers-vdso-2026-08-17' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull VDSO updates from Thomas Gleixner:
- Consolidate the VDSO datastore further and provide support for
mlock_all() and prefaulting.
- Provide 32-bit legacy time related functionality only if
CONFIG_COMPAT_32BIT_TIME is enabled. 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
