------------------------------------------------------
Subject: x86-64: Calgary - fold in redundant functions
From: Muli Ben-Yehuda <muli@xxxxxxxxxx>
After the bitmap changes we can get rid of the unlocked versions of
calgary_unmap_sg and iommu_free. Fold __calgary_unmap_sg and
__iommu_free into their calgary_unmap_sg and iommu_free, respectively.
