Subject: [ 26/86] futex: Revert "futex: Mark get_robust_list as deprecated"

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

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

From: Thomas Gleixner <tglx@...utronix.de>

commit fe2b05f7ca9f906be61dced5489f63b8b4d7c770 upstream.

This reverts commit ec0c4274e33c0373e476b73e01995c53128f1257.

get_robust_list() is in use and a removal would break existing user
space. With the permission checks in place it's not longer a security
hole. Remove the deprecation warnings.
