Heiko Carstens 504e75d0ed [S390] futex: let futex_atomic_cmpxchg_pt survive early functional tests. ... a0c1e9073e "futex: runtime enable pi and robust functionality" introduces a test wether futex in atomic stuff works or not. It does that by writing to address 0 of the kernel address space. This will crash on older machines where addressing mode switching is enabled but where the mvcos instruction is not available. Page table walking is done by hand and therefore the code tries to access current->mm which is NULL. Therefore add an extra check, so we survive the early test.
