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
