From 1b75a98556931f83129a222260dbc32a104b8bc3 Mon Sep 17 00:00:00 2001 From: attilio Date: Thu, 25 Feb 2010 14:13:39 +0000 Subject: Introduce the new kernel sub-tree x86 which should contain all the code shared and generalized between our current amd64, i386 and pc98. This is just an initial step that should lead to a more complete effort. For the moment, a very simple porting of cpufreq modules, BIOS calls and the whole MD specific ISA bus part is added to the sub-tree but ideally a lot of code might be added and more shared support should grow.
