The patch titled sparc64: use iommu_num_pages function in IOMMU code has been removed from the -mm tree. Its filename was sparc64-use-iommu_num_pages-function-in-iommu-code.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: sparc64: use iommu_num_pages function in IOMMU code From: Joerg Roedel <joerg.roedel@xxxxxxx> Signed-off-by: Joerg Roedel <joerg.roedel@xxxxxxx> Cc: "David S.
