Subject: [PATCH] powerpc: Use new printk extension %pS to print symbols on oops

From: Benjamin Herrenschmidt <[email-masked]>
Date: Mon, 07 Jul 2008 13:44:31 +1000

This changes the oops and backtrace code to use the new %pS
printk extension to print out symbols rather than manually
calling print_symbol.
