Date: Sun, 2 Aug 2009 10:45:39 +0200 (CEST) From: Julia Lawall <julia@...u.dk> To: hsweeten@...ionengravers.com, ryan@...ewatersys.com, linux-arm-kernel@...ts.arm.linux.org.uk, linux-kernel@...r.kernel.org, kernel-janitors@...r.kernel.org Subject: [PATCH 4/15] arch/arm/mach-ep93xx: Use DIV_ROUND_CLOSEST From: Julia Lawall <julia@...u.dk> The kernel.h macro DIV_ROUND_CLOSEST performs the computation (x + d/2)/d but is perhaps more readable.
