- Remove the interrupt timing infrastructure
This was added seven years ago to be used for power management purposes, but
that integration never happened.
- Clean up the remaining setup_percpu_irq() users
The memory allocator is available when interrupts can be requested so there
is not need for static irq_action. Move the remaining users to
request_percpu_irq() and delete the historical cruft.
- Warn when interrupt flag inconsistencies are detected in request*_irq().
Inconsistent flags can lead to hard to diagnose malfunction. The fallout of
this new warning has been addressed in next and the fixes are coming in via
the maintainer trees and the tip irq/cleanup pull requests.
- Invoke affinity notifier when CPU hotplug breaks affinity
Otherwise the code using the notifier misses the affinity change and
operates on stale information.
- The usual cleanups and improvements
