[PATCH] x86_64: no_iommu removal in pci-gart.c
In previous versions of pci-gart.c, no_iommu was used to determine if IOMMU was
disabled in the GART DMA mapping functions. This changed in 2.6.16 and now
gart_xxx() functions are only called if gart is enabled. Therefore, uses of
no_iommu in the GART code are no longer necessary and can be removed.
Also, it removes double deceleration of no_iommu and force_iommu in pci.h and
proto.h, by removing the deceleration in pci.h.
Lastly, end_pfn off by one error.
Tested (along with patch 1/2) on dual opteron with gart enabled, iommu=soft,
and iommu=off.
