[Qemu-stable] [PATCH v2] target/ppc: pass const string to kvmppc_is_mem_backend_page_size_ok()

[Greg Kurz]

This function has three implementations. Two are stubs that do nothing
and the third one only passes the obj_path argument to:

Object *object_resolve_path(const char *path, bool *ambiguous);
