From 22c841c9a465a6b29a6140fcc5dae9fdb3c8674d Mon Sep 17 00:00:00 2001 From: Paul Mackerras Date: Fri, 11 Nov 2005 22:34:43 +1100 Subject: [PATCH] powerpc: Initialize secondary CPU setup for 32-bit SMP 32-bit SMP powermacs weren't booting with ARCH=powerpc because the boot cpu wasn't saving away the state of various control registers, but the secondary CPUs were loading them from the uninitialized state. This adds the necessary save-state call.
