Current x86-64 patchkit for 2.6.5.

- Add drivers/firmware/Kconfig

- Clarify description of CONFIG_IOMMU_DEBUG

- Use correct gcc option to optimize for Intel CPUs

- Add EDD support (Matt Domsch)

- Add workaround for broken IOMMU on VIA hardware.  Uses swiotlb there now.

- Handle more than 8 local APICs (Suresh B Siddha) 

- Delete obsolete mtrr Makefile

- Add x86_cache_alignment and set it up properly for P4 (128 bytes instead
  of 64bytes).  Also report in /proc/cpuinfo

- Minor cleanup in in_gate_area

- Make asm-generic/dma-mapping.h compile with !CONFIG_PCI Just stub out all
  functions in this case.  This is mainly to work around sysfs.

- More !CONFIG_PCI compile fixes

- Make u64 sector_t unconditional
