4.8-stable review patch. If anyone has any objections, please let me know. ------------------ From: Jacob Pan <redacted> commit ec638db8cb9ddd5ca08b23f2835b6c9c15eb616d upstream. Commit 3105f234e0aba43e44e277c20f9b32ee8add43d4 replaced module cpu id table with a cpu feature check, which is logically correct. But we need the module device table to allow module auto loading.
