Benjamin Herrenschmidt 92ce74164e powerpc: Don't preempt_disable() in show_cpuinfo() ...

commit 349524bc0d upstream.

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.
