    [CIFS] Change pragma pack(1) to attribute(packed) to allow cifs on arm to access · 0753ca7b

    unaligned structures coming in off the wire
    
    gcc on arm processors generates very odd code with pragma pack specified -
    although it does pack the structures in some sense - it does not allow you
    to access unaligned elements in nested structures at the right offset as other
    architectures do.  Oddly enough though, specifying the structures as packed
    the long way - one by one with the packed attribute does work.  Rather than
    fighting over whether this is a gcc bug or some obscure side effect
    of pragma pack, it is easier to do what most (all but 96 other places in
    the kernel) do - and replace pragma pack with dozens of attribute(packed)
    structure qualifiers.  Much more verbose ... but at least it works.
