Actually, I think I figured it out.  

/// Arguments for GSP startup.
#[repr(C)]
pub(crate) struct GspArgumentsCached(
    bindings::GSP_ARGUMENTS_CACHED,
    [u8; GSP_PAGE_SIZE - core::mem::size_of::<bindings::GSP_ARGUMENTS_CACHED>()], // Padding to make
it 4K
);

impl GspArgumentsCached {
    /// Creates the arguments for starting the GSP up using `cmdq` as its command queue.
    pub(crate) fn new(cmdq: &Cmdq) -> Self {
        Self(
            bindings::GSP_ARGUMENTS_CACHED {
                messageQueueInitArguments: MessageQueueInitArguments::new(cmdq).0,
                bDmemStack: 1,
                ..Default::default()
            },
            [0u8; GSP_PAGE_SIZE - core::mem::size_of::<bindings::GSP_ARGUMENTS_CACHED>()],
        )
    }
}

If you think this is okay, I'll put it in v3.  I had to remove the #[repr(transparent)].  Is that
okay?  The code compiles and seems to work.
