Xen devel - Feb 2009 - [GIT PULL] x86/xen: Use xen-specific path for interrupt delivery

Rather than mapping event channels to vectors and then using the 
vector->irq mapping for interrupt delivery, just cut out the middleman 
and directly map event channels to irqs.  This allows for some more 
cleanups in the event handling code.

The following changes since commit 637f52a7cc5b3ae22354b7e45397375a17d626af:
  Jeremy Fitzhardinge (1):
        x86: unify do_IRQ()

are available in the git repository at:

  git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git jsgf/xen/irq

Jeremy Fitzhardinge (5):
      xen: set irq_chip disable
      xen: use our own eventchannel->irq path
      xen: pack all irq-related info together
      xen: remove irq bindcount
      xen: make sure that softirqs get handled at the end of event processing

Ok, never mind my comment on the do_IRQ() detail, this looks good after all,
you just consolidated what is there already in essence.

Pulled into tip/x86/apic [which had dependencies here], thanks Jeremy!

Btw., please remove leftover bits like:

+       //printk("cpu %d handling irq %d\n", smp_processor_id(),
info->irq);


	Ingo
