From: Jeff Dike Date: Wed, 27 Sep 2006 08:50:38 +0000 (-0700) Subject: [PATCH] uml: mark some tt-mode code X-Git-Tag: v2.6.19-rc1~936 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0915ee38c7db57ff41a7a68bcc02d0dd3b7b849b;p=linux-2.6 [PATCH] uml: mark some tt-mode code Mark a symbol and file as being tt-mode only. This shrinks the binary slightly when tt mode support is compiled out and makes it easier to identity stuff when tt mode is removed.
