From cb1b8209815594613650772eeb889c170107dad4 Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Thu, 21 Apr 2011 15:45:45 -0700 Subject: [PATCH] sparc: consolidate show_cpuinfo in cpu.c We have all the cpu related info in cpu.c - so move the remaining functions to support /proc/cpuinfo to this file.
