The patch titled input: fix accuracy of fixp-arith.h has been removed from the -mm tree. Its filename is input-fix-accuracy-of-fixp-arithh.patch This patch was probably dropped from -mm because it has now been merged into a subsystem tree or into Linus's tree, or because it was folded into its parent patch in the -mm tree. ------------------------------------------------------ Subject: input: fix accuracy of fixp-arith.h From: Anssi Hannula <anssi.hannula@xxxxxxxxx> Add the value of cos(90) = 0 to the table. This also moves the results so that sin(x) == sin(180-x) is true as expected.
