[PATCH] Remove safe_smp_processor_id()
And replace all users with ordinary smp_processor_id. The function was originally added to get some basic oops information out even if the GS register was corrupted. However that didn't work for some anymore because printk is needed to print the oops and it uses smp_processor_id() already. Also GS register corruptions are not particularly common anymore. This also helps the Xen port which would otherwise need to do this in a special way because it can't access the local APIC.
