Merge branch 'irq-upstream' of master.kernel.org:/pub/scm/linux/kernel/git/jgarzik/misc-2.6 

* 'irq-upstream' of master.kernel.org:/pub/scm/linux/kernel/git/jgarzik/misc-2.6:
  [SPARC, XEN, NET/CXGB3] use irq_handler_t where appropriate
  drivers/char/riscom8: clean up irq handling
  isdn/sc: irq handler clean
  isdn/act2000: fix major bug. clean irq handler.
  char/pcmcia/synclink_cs: trim trailing whitespace
  drivers/char/ip2: separate polling and irq-driven work entry points
  drivers/char/ip2: split out irq core logic into separate function
  [NETDRVR] lib82596, netxen: delete pointless tests from irq handler
  Eliminate pointless casts from void* in a few driver irq handlers.
  [PARPORT] Remove unused 'irq' argument from parport irq functions
  [PARPORT] Kill useful 'irq' arg from parport_{generic_irq,ieee1284_interrupt}
  [PARPORT] Consolidate code copies into a single generic irq handler
