From: Linus Torvalds Date: Wed, 18 May 2005 22:39:33 +0000 (-0700) Subject: [PATCH] prevent NULL mmap in topdown model X-Git-Tag: v2.6.12-rc5~48 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=49a43876b935c811cfd29d8fe998a6912a1cc5c4;p=pandora-kernel.git [PATCH] prevent NULL mmap in topdown model Prevent the topdown allocator from allocating mmap areas all the way down to address zero. We still allow a MAP_FIXED mapping of page 0 (needed for various things, ranging from Wine and DOSEMU to people who want to allow speculative loads off a NULL pointer). Tested by Chris Wright.
