7a1d67f9cb [breaking] Use integer atomic for GPU histogram. (#7180) 
On GPU we use rouding factor to truncate the gradient for deterministic results. This PR changes the gradient representation to fixed point number with exponent aligned with rounding factor.

    [breaking] Drop non-deterministic histogram.
    Use fixed point for shared memory.

This PR is to improve the performance of GPU Hist.

46c46829ce Fix model loading from stream (#7067) 
Fix bug introduced in 17913713b5 (allow loading from byte array)

When loading model from stream, only last buffer read from the input stream is used to construct the model.

This may work for models smaller than 1 MiB (if you are lucky enough to read the whole model at once), but will always fail if the model is larger.
