Subject: [PATCH] [PATCH] lockdep: add disable/enable_irq_lockdep() API

lockdep wants to use the disable_irq()/enable_irq() prototypes before they are
provied by the platform's asm/irq.h.  So move them out of the
CONFIG_GENERIC_HARDIRQS define - all architectures have a common prototype for
this anyway.

Add special lockdep variants of irq line disabling/enabling.

These should be used for locking constructs that know that a particular irq
context which is disabled, and which is the only irq-context user of a lock,
that it's safe to take the lock in the irq-disabled section without disabling
hardirqs.
