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

------------------
From: Richard Weinberger <[email protected]>

commit 1b627d5771312c92404b66f0a0b16f66036dd2e1 upstream.

365b1818 ("add f_flags to struct statfs(64)") resized f_spare within
struct statfs which caused a UML crash.  There is no need to copy f_spare.
