[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.
