KVM: nVMX: shadow pin based execution controls
The VMX_PREEMPTION_TIMER flag may be toggled frequently, though not *very* frequently. Since it does not affect KVM's dirty logic, e.g. the preemption timer value is loaded from vmcs12 even if vmcs12 is "clean", there is no need to mark vmcs12 dirty when L1 writes pin controls, and shadowing the field achieves that.

Subsequent calls to of_find_node_by_phandle() will incorrectly find the stale entry. Remove the node from the cache. Add paranoia checks in of_find_node_by_phandle() as a second level of defense (do not return cached node if detached, do not add node to cache if detached). Fixes: 0b3ce78e90fc ("of: cache phandle nodes to reduce cost of of_find_node_by_phandle()") Reported-by: Michael Bringmann <mwb@linux.vnet.ibm.com> Cc: stable@vger.kernel.org # v4.17+ Signed-off-by: Frank Rowand <frank.rowand@sony.com> Signed-off-by: Rob Herring <robh@kernel.org> 2018-11-08of: overlay: set node fields from properties when add new overlay nodeFrank Rowand Overlay nodes added by add_changeset_node() do not have the node fields name, phandle, and type set. The node passed to __of_attach_node() when the add node changeset entry is processed does not contain any properties. The node's properties are located in add property changeset entries that will be processed after the add node changeset is applied. Set the node's fields in the node contained in the add node changeset entry and do not set them to incorrect values in add_changeset_node(). A visible symptom that is fixed by this patch is the names of nodes added by overlays that have an entry in /sys/bus/platform/drivers/*/ will contain the unit-address but the node-name will be <NULL>, for example, "fc4ab000.<NULL>". After applying the patch the name, in this example, for node restart@fc4ab000 is "fc4ab000.restart".

This patch may result in memory leaks from code that directly calls the dynamic node add and delete functions directly instead of using changesets. This commit should result in powerpc systems that dynamically allocate a node, then later deallocate the node to have a memory leak when the node is deallocated. The next commit will fix the leak.
