Andi Kleen 354542d034 x86/microcode/intel: Do not issue microcode updates messages on each CPU
On large systems the microcode driver is very noisy, because it prints a
line for each CPU. The lines are redundant because usually all CPUs are
updated to the same microcode revision.

All other subsystems have been patched previously to not print a line
for each CPU. Only the microcode driver is left.

Only print an microcode revision update when something changed. This
results in typically only a single line being printed.
