Debugging some bizare memory corruption in certain kernel configs on
some machines, I noticed MPSC (1st gen Intel X64 Nocona) is missing in
selecting X86_INTEL_USERCOPY and X86_USE_PPRO_CHECKSUM. Unless someone
has a good reason not to, I think MPSC should select the two, and
maybe MATOM should also made select X86_INTEL_USERCOPY?
