Message

This small series fixes two issues with spinlock debug code and adds
lock debug code to rwlocks in order to catch IRQ violations.

Juergen Gross (3):
  xen/spinlocks: spin_trylock with interrupts off is always fine
  xen/locking: harmonize spinlocks and rwlocks regarding preemption
  xen/rwlock: add check_lock() handling to rwlocks
