2007-10-30x86 gart: rename symbols only used for the GART implementationJoerg Roedel1-4/+4
This patch renames the 4 symbols iommu_hole_init(), iommu_aperture, iommu_aperture_allowed, iommu_aperture_disabled. All these symbols are only used for the GART implementation of IOMMUs. It adds and additional gart_ prefix to them. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2007-10-30x86 gart: make some variables and functions staticJoerg Roedel1-4/+4
This patch makes some functions and variables static in pci-gart_64.c which are not used somewhere else. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com> Acked-by: Muli Ben-Yehuda <muli@il.ibm.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2007-10-30x86 gart: rename iommu.h to gart.hJoerg Roedel1-1/+1
This patch renames the include file asm-x86/iommu.h to asm-x86/gart.h to make clear to which IOMMU implementation it belongs. The patch also adds "GART" to the Kconfig line.

2007-10-29x86: fix pci-gart failure handlingFUJITA Tomonori1-1/+1
blk_rq_map_sg doesn't initialize sg->dma_address/length to zero anymore. Some low level drivers reuse sg lists without initializing so IOMMUs might get non-zero dma_address/length. If map_sg fails, we need pass the number of the mapped entries to gart_unmap_sg. Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-10-25x86: pci-gart fixFUJITA Tomonori1-2/+1
map_sg could copy the last sg element to another position (if merging some elements). It breaks sg chaining. This copies only dma_address/length instead of the whole sg element. Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
