[PATCH v2 0/2] KVM/ARM implementation of PSCI

[Marc Zyngier]

This is an implementation of the Power State Coordination Interface,
as described there (registration required):
http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.den0022a/index.html

It allows CPUs to be powered on, off, suspended or migrated. This
series is only concerned with power-{on,off}. KVM Tool uses it to boot
SMP VMs. This is also supported by the mach-virt platform:

git://git.kernel.org/pub/scm/linux/kernel/git/will/linux.git virt/mach

Tested on the arm64 model, based on kvm-arm-master as of today.

>From v1:
- Documentation
- Move the one-time init to a separate function
- "One mask fits all"
- Use wait_event_interruptible instead of the open coded version
