3.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Avi Kivity <a...@redhat.com> commit cb09cad44f07044d9810f18f6f9a6a6f3771f979 upstream. Probably a leftover from the early days of self-patching, p6nops are marked __initconst_or_module, which causes them to be discarded in a non-modular kernel. If something later triggers patching, it will overwrite kernel code with garbage.
