    I have a concern; you seem to be patching potentially "live" code....

    there are basically two options
    1) you run the risk of triple faulting (patching an instruction while
    some other core/cpu may be decoding it may cause a triple fault)
    2) you do an IPI to all other cpus and prevent them from executing any
    code except a small loop during the patching... this is expensive.

    To be honest, neither sound very attractive to me ;(
