[PATCH v2 0/4] arm64: Fix cpuidle/suspend with pseudo-NMI enabled

[Marc Zyngier]

This is a follow-up on the series posted at [1], with some added
fixes. The main difference is the covering of system suspend, although
it is untested (the GICv3 boxes I have don't support system
suspend...).

Tested on an Ampere Altra system.

* From v1:
  - Moved the wrapping of cpu_suspend() into the body of the function,
    now covering system suspend as well
  - Added RBs, TBs.
