[Andi Kleen]

2.6.35-longterm review patch.  If anyone has any objections, please let me know.

------------------
From: Kees Cook <kees.cook@xxxxxxxxxxxxx>

commit 5b919f833d9d60588d026ad82d17f17e8872c7a9 upstream.

Commit fe10ae53384e48c51996941b7720ee16995cbcb7 adds a memset() to clear
the structure being sent back to userspace, but accidentally used the
wrong size.
