    Subject[patch 27/71] x86: Fix 27-rc crash on vsmp due to paravirt during module load
    2.6.26-stable review patch.  If anyone has any objections, please let us

    From: Ravikiran Thirumalai <>

    commit 05e12e1c4c09cd35ac9f4e6af1e42b0036375d72 upstream.

    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"
