[LinuxBIOS] r2588 - in trunk/LinuxBIOSv2/src: arch/i386/include cpu/amd/model_fxx cpu/x86/32bit cpu/x86/mtrr
Author: stepan Date: 2007-04-06 21:49:05 +0200 (Fri, 06 Apr 2007) New Revision: 2588
Modified: trunk/LinuxBIOSv2/src/arch/i386/include/stdint.h trunk/LinuxBIOSv2/src/cpu/amd/model_fxx/init_cpus.c trunk/LinuxBIOSv2/src/cpu/amd/model_fxx/processor_name.c trunk/LinuxBIOSv2/src/cpu/x86/32bit/entry32.inc trunk/LinuxBIOSv2/src/cpu/x86/mtrr/earlymtrr.c trunk/LinuxBIOSv2/src/cpu/x86/mtrr/mtrr.c Log: This is part of the outstanding mcp55 commit from January 18th. It will likely break the build, since it is only a small part, but it needs to go in at some point and doing it directory by directory makes things easier.
