    SubjectRe: [Oops 1/2]Something wrong with copy_from_user() function - possible false positive due bug in gcc 4.6

    You my wantto look here

    It is regression in gcc 4.6

    Particulry this error happens in binfmt_misc.c file.
    gcc 4.6 errornously print error in this file.

    However I could not find such behavior
    nowhere in rest of kernel. But it can still
    be a case If you use gcc 4.6.

    If you are using gcc 4.5 or older, it is probably
    genuine error, or someone is using a destination
    buffer which is unknown size and gcc cannot
    prove it is big enaugh to hold data.
