This patchset is a sequel to my patchset to fix iommu segment boundary problems: http://www.mail-archive.com/linux-scsi@xxxxxxxxxxxxxxx/msg11919.html This adds new IOMMU helper functions for the free area management. These functions take care of LLD's segment boundary limit for IOMMUs. They are useful for IOMMUs that use bitmap for the free area management. The helper functions are very low level. They just find a free area in bitmap appropriate for low level drivers. The IOMMUs continue to use their hardware specific techniques easily with the low level helper functions. This patchset converts three IOMMUs: POWERPC, X86 calgary, and X86 gart but I tested POWERPC patch. The rest are only compile tested since I don't have hardware. This is against 2.6.24-rc4-mm1. - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
