[PATCH v2 0/3] rust: Add irq abstraction, SpinLockIrq

[Lyude Paul <lyude@redhat.com>]

This adds a simple interface for disabling and enabling CPUs, along with
the ability to mark a function as expecting interrupts be disabled -
along with adding bindings for spin_lock_irqsave/spin_lock_irqrestore().

Current example usecase (very much WIP driver) in rvkms:

specifically drivers/gpu/drm/rvkms/crtc.rs

(The kunit tests also compile)
