From: Jeff Vander Stoep <jeffv@google.com> 3.12-stable review patch. If anyone has any objections, please let me know. =============== commit bf0c4e04732479f650ff59d1ee82de761c0071f0 upstream. Move the poison pointer offset to 0xdead000000000000, a recognized value that is not mappable by user-space exploits.
