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
