Patch is now in Linus's tree:

commit 145e1c0023585e0e8f6df22316308ec61c5066b2
Author: Hugh Dickins <hugh@...itas.com>
Date:   Sat Nov 1 21:41:40 2008 -0700

    sparc64: Fix __copy_{to,from}_user_inatomic defines.
    
    Alexander Beregalov reports oops in __bzero() called from
    copy_from_user_fixup() called from iov_iter_copy_from_user_atomic(),
    when running dbench on tmpfs on sparc64: its __copy_from_user_inatomic
    and __copy_to_user_inatomic should be avoiding, not calling, the fixups.
