From 10b614eaa847447c2c8646030728309d14bd2d05 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Tue, 24 Feb 2009 21:41:32 +0100 Subject: [PATCH] x86_32: summit_32, use BAD_APICID Use BAD_APICID instead of 0xFF constants in summit_cpu_mask_to_apicid. Also remove bogus comments about what we actually return.
