    x86/fpu/mpx: Rework MPX 'xstate' types · 1126cb45
    Dave Hansen authored
    MPX includes two separate "extended state components".  There is
    no real need to have an 'mpx_struct' because we never really
    manage the states together.
    
    We also separate out the actual data in 'mpx_bndcsr_state' from
    the padding.  We will shortly be checking the state sizes
    against our structures and need them to match.  For consistency,
    we also ensure to prefix these types with 'mpx_'.
    
    Lastly, we add some comments to mirror some of the descriptions
    in the Intel documents (SDM) of the various state components.
