The AMD side of the loader issues the microcode revision for each logical thread on the system, which can become really noisy on huge machines. And doing that doesn't make a whole lot of sense - the microcode revision is already in /proc/cpuinfo. So in case one is interested in the theoretical support of mixed silicon steppings on AMD, one can check there. What is also missing on the AMD side - something which people have requested before - is showing the microcode revision the CPU had *before* the early update. So abstract that up in the main code and have the BSP on each vendor provide those revision numbers. Then, dump them only once on driver init. On Intel, do not dump the patch date - it is not needed.
