Subject: [PATCH v18 2/5] rust: helper: Add spin_{un,}lock_irq_{enable,disable}() helpers

From: Boqun Feng <boqun.feng@...il.com>

spin_lock_irq_disable() and spin_unlock_irq_enable() are inline
functions, to use them in Rust, helpers are introduced. This is for
interrupt disabling lock abstraction in Rust.
