Merge branch 'release-2.6.27' of git://git.kernel.org/pub/scm/linux/kernel/git/ak/linux-acpi-merge-2.6

* 'release-2.6.27' of git://git.kernel.org/pub/scm/linux/kernel/git/ak/linux-acpi-merge-2.6: (87 commits)
  Fix FADT parsing
  Add the ability to reset the machine using the RESET_REG in ACPI's FADT table.
  ACPI: use dev_printk when possible
  PNPACPI: add support for HP vendor-specific CCSR descriptors
  PNP: avoid legacy IDE IRQs
  PNP: convert resource options to single linked list
  ISAPNP: handle independent options following dependent ones
  PNP: remove extra 0x100 bit from option priority
  PNP: support optional IRQ resources
  PNP: rename pnp_register_*_resource() local variables
  PNPACPI: ignore _PRS interrupt numbers larger than PNP_IRQ_NR
  PNP: centralize resource option allocations
  PNP: remove redundant pnp_can_configure() check
  PNP: make resource assignment functions return 0 (success) or -EBUSY (failure)
  PNP: in debug resource dump, make empty list obvious
  PNP: improve resource assignment debug
  PNP: increase I/O port & memory option address sizes
  PNP: introduce pnp_irq_mask_t typedef
  PNP: make resource option structures private to PNP subsystem
  PNP: define PNP-specific IORESOURCE_IO_* flags alongside IRQ, DMA, MEM
