The patch titled kernel: add bit rotation helpers for 16 and 8 bit has been removed from the -mm tree. Its filename was kernel-add-bit-rotation-helpers-for-16-and-8-bit.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: kernel: add bit rotation helpers for 16 and 8 bit From: Harvey Harrison <harvey.harrison@xxxxxxxxx> Will replace open-coded variants elsewhere. Done in the same style as the 32-bit versions.
