From 11cd0bc140b5d66566c9eb49c1058737888cd75c Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Mon, 23 Jun 2008 19:51:10 -0700 Subject: [PATCH] x86: move some func calling from setup_arch to paging_init those function depend on paging setup pgtable, so they could access the ram in bootmem region but just get mapped.
