OK, I've sent v2.
But again, I won't argue if you prefer to keep tick_do_timer_boot_cpu and add
WARN_ON_ONCE(tick_cpu != tick_do_timer_boot_cpu) before WRITE_ONCE(tick_do_timer_cpu).
In this case another patch makes no sense, I'll update this one.
Just tell me what you like more. Sorry for the chaotic emails.
Oleg.
