On an SMP system with only one global clockevent and a dummy
clockevent per CPU we run into problems. We want the dummy
clockevents to be registered as the per CPU tick devices, but
we can

Nobody has noticed this so far so I'm ok waiting for 3.10 on this one. Also
it doesn't improve stability (debug feature) so I don't see a reason to send
it to stable.

Similarly, what if someone wants to write a more complex mapping for some
reason?
We should be able to handle it if we use the standard

Yes, that's already covered in the binding.
Might we have a hardware / firmware configuration where the kernel can only
access
the secondary view?
I don't see how this is possible. The CNTACRn

should be possible to support it by searching for at least two
frames where one frame has the virtual capability and then
updating KVM timers to support it.

There isn't any reason why we don't pass the event here and we'll
need it in the near future for memory mapped arch timers anyway.

I don't see why not but I don't have any interest in pursuing it.

Currently there are two problems when we try to stop local timer.
First, it calls set_mode function directly so mode state is not
updated for the clock event device. Second, it makes the device
unused
