32c0bb3a76 Converted all wait/wakeup runqueue lock/unlock paths to irq versions.
Irqs can now touch runqueues and do async wakeups. This necessitated
that we implement all wake up wait and runqueue locking work with irqs.

All this, assumes that in an SMP setup we may have cross-cpu wake ups,
runqueue manipulation. If we later decide that we only wake up threads
in the current container, (and lock containers to cpus) we won't really
need spinlocks, or irq disabling anymore. The current set up might be
trivially less responsive, but is more flexible.

b1614191b3 Reverted all changes - userspace devices mapped at initialization.
This is much simpler, no device map/unmap maintenance at run-time,
no lazy device mapping etc.

59af5d3794 Made changes to map devices dynamically upon irq registration.
All will be reverted since mapping devices statically is much simpler.

6e40a2b601 Preliminary irq registration call + irq capability checking
Need to add irqctrl capabilities and irq bits to device memory
caps.

Also need to initialize irq field of devmem caps.
