The purpose of the "meaningless log messages" is to show the CPU configuration of the machine. Example: x86: Booting SMP configuration: .... node #0, CPUs: #1 #2 #3 ... #63 .... node #1, CPUs: #64 #65 #66 ... #127 where the ellipsis "..." has the other core numbers which I've not added here for readability. I guess we can make "Disabled fast string operations" a once message so that it doesn't fire on every CPU as that's pointless and redundant. But that's all cosmetic stuff - the "promotion" of info messages to warn is the bigger issue which Petr can comment on. HTH.
