Subject: [PATCH 3.10 05/56] arm64: kconfig: Move LIST_POISON to a safe value

3.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jeff Vander Stoep <jeffv@...gle.com>

commit bf0c4e04732479f650ff59d1ee82de761c0071f0 upstream.

Move the poison pointer offset to 0xdead000000000000, a
recognized value that is not mappable by user-space exploits.
