Heiko Carstens 3f12ebce6a [S390] uaccess: Always access the correct address space.
The current uaccess page table walk code assumes at a few places that
any access is a user space access. This is not correct if somebody
has issued a set_fs(KERNEL_DS) in advance.
Add code which checks which address space we are in and with this make
sure we access the correct address space. This way we get also rid of
the dirty
if (!currrent-mm)
	return -EFAULT;
hack in futex_atomic_cmpxchg_pt.
