 1. Correct locking for lazy storage key handling
    A test loop with multiple CPUs triggered a race in the lazy storage
    key handling as introduced by commit 934bc131efc3e4be6a52f7dd6c4dbf
    (KVM: s390: Allow skeys to be enabled for the current process). This
    race should not happen with Linux guests, but let's fix it anyway.
    Patch touches !/kvm/ code, but is from the s390 maintainer.
 
 2. Better handling of broken guests
    If we detect a program check loop we stop the guest instead of
    wasting CPU cycles.
 
 3. Better handling on MVPG emulation
    The move page handling is improved to be architecturally correct.
 
 3. Trace point rework
    Let's rework the kvm trace points to have a common header file (for
    later perf usage) and provided a table based instruction decoder.
 
 4. Interpretive execution of SIGP external call
    Let the hardware handle most cases of SIGP external call (IPI) and
    wire up the fixup code for the corner cases.
 
 5. Initial preparations for the IBC facility
    Prepare the code to handle instruction blocking
