Hi Palmer, could this patchset be merged into v5.15, it fixes the
serious problems about the basic time api.

Adapt to the latest code.

v2->v1:
Add patch "Refactor asm/vdso.h" to avoid vdso.lds syntax error if
CONFIG_GENERIC_TIME_VSYSCALL=n.

1) Move vdso data page up front and introduce enum vvar_pages, This makes it
easier to introduce new feature TIME_NS.

2) In arch_setup_additional_pages(), make Wait for the lock in the killable mode
and return with EINTR if the task got killed while waiting.
