Subject: [PATCH v4 0/3] rust: Add irq abstraction, SpinLockIrq

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

Lyude Paul (3):
  rust: Introduce irq module
  rust: sync: Introduce lock::Backend::Context
  rust: sync: Add SpinLockIrq
