This is seriously wrong.  For 3.9 you _need_ asmlinkage_protect() in that
thing; by the time when that went into the tree, mainline already had
it generated automatically by SYSCALL_DEFINE, so there was no point in
that part of patch - the switch to SYSCALL_DEFINE alone did the job.
For 3.9 it's very much needed; as the matter of fact, in 3.9 that commit
is a no-op in the form you took.

We can grab all prereqs into 3.9-stable (there's not that much of those),
but that would be much more intrusive than the variant adding explicit
asmlinkage_protect() in those two syscalls.
