powerpc/rfi-flush: Make it possible to call setup_rfi_flush() again commit abf110f3e1cea40f5ea15e85f5d67c39c14568a7 upstream. For PowerVM migration we want to be able to call setup_rfi_flush() again after we've migrated the partition. To support that we need to check that we're not trying to allocate the fallback flush area after memblock has gone away (i.e., boot-time only).
