This patchset adds support for polling in idle via poll_idle() on
arm64.

There are two main changes in this version:

1. rework the series to take Catalin Marinas' comments on the semantics
   of smp_cond_load_relaxed() (and how earlier versions of this
   series were abusing them) into account.

There was a recent series adding resilient spinlocks which might also have
use for an smp_cond_load_{acquire,release}_timeout() interface.
