The required 2 patches can be found in the following patch series: https://lkml.org/lkml/2011/3/31/213 "[PATCH 01/12] lib: bitmap: Added alignment offset for bitmap_find_next_zero_area()" https://lkml.org/lkml/2011/3/31/211 "[PATCH 02/12] lib: genalloc: Generic allocator improvements" https://lkml.org/lkml/2011/3/31/207 For easier testing I've uploaded the whole IOMMU patch series and prerequisites to public GIT repository to vb2-iommu branch (will be available in a about 2 hours): http://git.infradead.org/users/kmpark/linux-2.6-samsung/shortlog/refs/heads/vb2- iommu git://git.infradead.org/users/kmpark/linux-2.6-samsung vb2-iommu Best regards -- Marek Szyprowski Samsung Poland R&D Center -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
