[ 50/52] x86/alternatives: Fix p6 nops on non-modular kernels
3.4-stable review patch. If anyone has any objections, please let me know.
--
From: Avi Kivity
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.
