Hi,

looks like the patch is broken (at least it does something different than the 
non-stable patch does).

It seems to be a problem with the way GNU patch solved the conflicts with the 
slightly different orig file (moved the hunks together when it shouldn't 
have). GregKH also had this problem [1]

Kind regards,
