It's not that bad; if userspace is running, the cpu isn't idle, so
there isn't the motivation to go tickless on that cpu. In other
words, if every cpu has suspended ticks, then no cpu can be running
stuff that needs to look at this page.

If I read the patch correctly, none of those legacy RTC ticks
can ever be suspended though?
