x86: fix 27-rc crash on vsmp due to paravirt during module load
27-rc fails to boot up if configured to use modules.
Turns out vsmp_patch was marked __init, and vsmp_patch being the
pvops 'patch' routine for vsmp, a call to vsmp_patch just turns out
to execute a code page with series of 0xcc (POISON_FREE_INITMEM -- int3).
vsmp_patch has been marked with __init ever since pvops, however,
apply_paravirt can be called during module load causing calls to
freed memory location.
Since apply_paravirt can only be called during init/module load, make
vsmp_patch with "__init_or_module"
