From: Thomas Gleixner Date: Sun, 30 Oct 2005 23:03:00 +0000 (-0800) Subject: [PATCH] jiffies_64 cleanup X-Git-Tag: v2.6.15-rc1~59^2~15^2~60 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ecea8d19c9f0ebd62ddaa07fc919ff4e4b820d99;p=linux-2.6 [PATCH] jiffies_64 cleanup Define jiffies_64 in kernel/timer.c rather than having 24 duplicated defines in each architecture.
