    npx: Extend fpusave/fpurstor() to accept an XSAVE mask argument
    
    XSAVE/XRSTOR requires a mask argument that determines the
    components/states to save/restore.  Thus this argument controls the
    save area size.
    
    Extend fpusave/fpurstor() functions to accept an XSAVE mask argument,
    so the caller can choose the wanted components/states to save/restore
    and knows the exact area size.
    
    NVMM will use this feature.
