From e75eac33b5c7f797e4b2ddcb39183cf268e26822 Mon Sep 17 00:00:00 2001 From: Jeremy Fitzhardinge Date: Sun, 25 Jun 2006 05:46:50 -0700 Subject: [PATCH] Clean up and refactor i386 sub-architecture setup Clean up and refactor i386 sub-architecture setup. This change moves all the code from the asm-i386/mach-*/setup_arch_pre/post.h headers, into arch/i386/mach-*/setup.c. mach-*/setup_arch_pre.h is renamed to setup_arch.h, and contains only things which should be in header files. It is purely code-motion; there should be no functional changes at all. Several functions in arch/i386/kernel/setup.c needed to be made non-static so that they're visible to the code in mach-*/setup.c. asm-i386/setup.h is used to hold the prototypes for these functions.
