Merge tag 'irqdomain-for-linus' of git://git.secretlab.ca/git/linux-2.6 

Pull irqdomain bug fixes from Grant Likely:
 "This branch fixes a bug in irq_create_mapping() where an error return
  from irq_alloc_desc_from() gets ignored.

  It also removes irq_virq_count to fix a bug on powerpc where the
  irqdomain code does not find irqs allocated above the CONFIG_NR_IRQS
  boundary.

  The remaining patches get rid of an completely pointless export and
  fix some minor bugs in the irqdomain debug output."

* tag 'irqdomain-for-linus' of git://git.secretlab.ca/git/linux-2.6:
  irq_domain: Move irq_virq_count into NOMAP revmap
  irqdomain: Fix debugfs formatting
  irq_domain: correct the debugfs file name
  irq: Kill pointless irqd_to_hw export
  irq/irq_domain: Quit ignoring error returns from irq_alloc_desc_from().
