Message-ID: <476EB3FA.5090607@gmail.com> Date: Sun, 23 Dec 2007 22:16:10 +0300 From: Dmitri Vorobiev <dmitri.vorobiev@...il.com> To: jsun@...sta.com CC: jsun@...sun.net, Linux-kernel <linux-kernel@...r.kernel.org> Subject: [PATCH 2.6] remove Documentation/mips/GT64120.README Being related to 2.4 kernel, the information presented in the `Documentation/mips/GT64120.README' file is outdated. Worse, the document contents are plain misleading nowadays because the text mentions files and directories, which have been deleted, moved or restructured for 2.6. In my opinion, this file should be deleted from the 2.6 kernel tree.
