mark these a _GPL export. Perhaps even mark the symbol deprecated, to be
unexported once we fix raid6.
read / write cr0 must not be GPL, since kernel_fpu_end uses them and is
inline. clts I don't think matters.

these should be _GPL too. If any module uses it and breaks a user's box
we need that big licensing hint to be able to debug them ...
Perhaps also, MSRs are too dangerous for binary modules to be messing with.
Agree on halt - but wbinvd can theoretically be used for device mapped
memory consistency.
