Dammit. Why the heck can ARM folks not route their stuff through the
relevant maintainers? Because ARM is a different universe with
different rules or what?
Of course this crap is already in Linus next branch, so it essentially
blocks me from sending my pending timers/core branch.
Patch below. Linus, can you please apply this?
I've ranted about this before. It's not the first time that ARM breaks
stuff I maintain.
Again: Send your stuff against drivers/clocksource and drivers/irqchip
to the maintainers.
I'm happy to provide you a separate branch to pull that stuff from me,
if you have dependencies on that, but I really don't want to see any
of this again, ever.
Yours seriously grumpy

The newly merged versatile sched clock support uses a deprecated
interface. Of course that patch got routed through the ARM tree
instead of going through the relevant maintainer tree.
Use the proper interface so we can get rid of the cruft.
