[PATCH v4 0/8] lockdep: Change IRQ state tracking to use per-cpu variables

[Peter Zijlstra]

Ahmed and Sebastian wanted additional lockdep_assert*() macros and ran into
header hell. I figured using per-cpu variables would cure that, and also
ran into header hell, still tracktable though.

By moving the IRQ state into per-cpu variables we remove the dependency on
task_struct.

Patches go on top of anything recent I think, an actual git tree with them
in is (for now) here:

  git://git.kernel.org/pub/scm/linux/kernel/git/peterz/queue.git locking/irqstate

Which 0day blessed with 0 build fails.
