The patch titled introduce lower_32_bits() macro has been removed from the -mm tree. Its filename was introduce-lower_32_bits-macro.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: introduce lower_32_bits() macro From: Joerg Roedel <joerg.roedel@xxxxxxx> The file kernel.h contains the upper_32_bits macro. This patch adds the other part, the lower_32_bits macro. Its first use will be in the driver for AMD IOMMU. Cc: H.
