* drivers/base/iommu.c: add missing includesAndrew Morton2009-05-061-0/+2
| | | | | | | | | | Fix zillions of -mm x86_64 allmodconfig build errors - the file uses EXPORT_SYMBOL() and kmalloc but misses the needed includes.

* add frontend implementation for the IOMMU APIJoerg Roedel2009-01-031-0/+100
This API can be used by KVM for accessing different types of IOMMUs to do device passthrough to guests. Beside that this API can also be used by device drivers to map non-linear host memory into dma-linear addresses to prevent sgather-gather DMA. UIO may be another user for this API.
