Subject: [PATCH v7 0/3] rust: Add local_irq abstraction, SpinLockIrq
This adds a token for annotating contexts where IRQs may be disabled on
non-PREEMPT_RT kernels, a way to use these tokens with Lock types, and
introduces bindings for spin_lock_irqsave() and
spin_unlock_irqrestore().
This patch series depends on the NotThreadSafe type from Alice:

(Please re-review, since there's been some changes here!)
