Thomas Gleixner 47ee94efcc sched/mmcid: Protect transition on weakly ordered systems
Shrikanth reported a hard lockup which he observed once. The stack trace
shows the following CID related participants:

  NIP: mm_get_cid+0xe8/0x188

   system_call_exception+0x128/0x390
   system_call_vectored_common+0x15c/0x2ec

The task on CPU11 is running the CID ownership mode change fixup function
and is stuck on a runqueue lock. The task on CPU23 is trying to get a CID
from the pool with the same runqueue lock held, but the pool is empty.

After decoding a similar issue in the opposite direction switching from per
task to per CPU mode the tool which models the possible scenarios failed to
come up with a similar loop hole.

This showed up only once, was not reproducible and according to tooling not
related to a overlooked scheduling scenario permutation. But the fact that
it was observed on a PowerPC system gave the right hint: PowerPC is a
weakly ordered architecture.

The transition mechanism does:

    WRITE_ONCE(mm->mm_cid.transit, MM_CID_TRANSIT);
    WRITE_ONCE(mm->mm_cid.percpu, new_mode);

    fixup()

    WRITE_ONCE(mm->mm_cid.transit, 0);

mm_cid_schedin() does:

    if (!READ_ONCE(mm->mm_cid.percpu))
       ...
       cid |= READ_ONCE(mm->mm_cid.transit);

so weakly ordered systems can observe percpu == false and transit == 0 even
if the fixup function has not yet completed. As a consequence the task will
not drop the CID when scheduling out before the fixup is completed, which
means the CID space can be exhausted and the next task scheduling in will
loop in mm_get_cid() and the fixup thread can livelock on the held runqueue
lock as above.

This could obviously be solved by using:
     smp_store_release(&mm->mm_cid.percpu, true);
and
     smp_load_acquire(&mm->mm_cid.percpu);

but that brings a memory barrier back into the scheduler hotpath, which was
just designed out by the CID rewrite.

That can be completely avoided by combining the per CPU mode and the
transit storage into a single mm_cid::mode member and ordering the stores
against the fixup functions to prevent the CPU from reordering them.

That makes the update of both states atomic and a concurrent read observes
always consistent state.

The price is an additional AND operation in mm_cid_schedin() to evaluate
the per CPU or the per task path, but that's in the noise even on strongly
ordered architectures as the actual load can be significantly more
expensive and the conditional branch evaluation is there anyway.
