[PATCH] x86: Fix 27-rc crash on vsmp due to paravirt during module load

[Ravikiran G Thirumalai <kiran@scalex86.org>]

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).  Since apply_paravirt can only be called during
init/module load, make vsmp_patch with "__init_or_module"

Please apply

Thanks,
Kiran

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 bootup and module load,
mark vsmp patch with "__init_or_module"
