Author: jhb Date: Thu Sep 4 01:46:06 2014 New Revision: 271076 URL: http://svnweb.freebsd.org/changeset/base/271076 Log: - Move prototypes for various functions into out of C files and into <machine/md_var.h>. - Move some CPU-related variables out of i386/i386/identcpu.c to initcpu.c to match amd64. - Move the declaration of has_f00f_hack out of identcpu.c to machdep.c. - Remove a misleading comment from i386/i386/initcpu.c (locore zeros the BSS before it calls identify_cpu()) and remove explicit zero assignments to reduce the diff with amd64.
