From: Roland Dreier <rdreier@xxxxxxxxx>
I was recently lucky enough to get a 64-CPU system, so my kernel log
ends up with 64 lines like:
ACPI: CPU0 (power states: C1[C1] C2[C3])
This is pretty useless clutter because this info is already available
after boot from both /sys/devices/system/cpu/cpu*/cpuidle/state?/ as
well as /proc/acpi/processor/CPU*/power.
So just delete the code that prints the C-states in processor_idle.c.
