Paolo,
Please do a pull from my kvm-ppc-fixes branch to get one more commit
for 4.13. It adds mutual exclusion between list_add_rcu and
list_del_rcu calls on the kvm->arch.spapr_tce_tables list. Without
this, userspace could potentially trigger corruption of the list and
cause a host crash or worse.
Thanks,
Paul.
