From 8621b81c744ff8880a1efe095a4dcd09763ddb5a Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Thu, 7 Dec 2006 02:14:03 +0100 Subject: [PATCH] [PATCH] i386: Reserve kernel memory starting from _text Currently when we are reserving the memory the kernel text resides in we start at __PHYSICAL_START which happens to be correct but not very obvious. In addition when we start relocating the kernel __PHYSICAL_START is the wrong value, as it is an absolute symbol that does not get relocated. By starting the reservation at __pa_symbol(_text) the code is clearer and will be correct when relocated. Signed-off-by: Eric W.
