Benjamin Herrenschmidt 349524bc0d powerpc: Don't preempt_disable() in show_cpuinfo()
This causes warnings from cpufreq mutex code. This is also rather
unnecessary and ineffective. If we really want to prevent concurrent
unplug, we could take the unplug read lock but I don't see this being
critical.
