The patch titled Avoid divide in IS_ALIGN has been removed from the -mm tree. Its filename was avoid-divide-in-is_align.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: Avoid divide in IS_ALIGN From: Herbert Xu <herbert@xxxxxxxxxxxxxxxxxxx> I was happy to discover the brand new IS_ALIGN macro and quickly used it in my code. To my dismay I found that the generated code used division to perform the test. This patch fixes it by changing the % test to an &. This avoids the division.
