[PATCH v4 02/16] KVM: PPC: Use RCU for arch.spapr_tce_tables

2014-07-30 Thread Alexey Kardashevskiy
At the moment spapr_tce_tables is not protected against races. This makes use of RCU-variants of list helpers. As some bits are executed in real mode, this makes use of just introduced list_for_each_entry_rcu_notrace(). This converts release_spapr_tce_table() to a RCU scheduled handler. Signed-of
