It depends if the MSR may be considered global, or is required to be per-cpu. Need to refresh my memory on this, but I remember reading this

Machine Check MSRs need to be per CPU. The latest kernels have some support
for "shared banks" (between CPUs) but it's better to not have it and
older OS don't like it.

In the case of the hypercall page MSR, it is global and shared among all processors.
