We can still amend that - is this changelog what you had in mind:

nohz: Reset next_tick cache even when the timer has no regs

Handle tick interrupts whose regs are NULL, out of general paranoia. It happens
when hrtimer_interrupt() is called from non-interrupt contexts, such as hotplug
CPU down events.

Or you can send me a longer version as well.
