    [PATCH] i386: Relocatable kernel support · 968de4f0
    Eric W. Biederman authored
    This patch modifies the i386 kernel so that if CONFIG_RELOCATABLE is
    selected it will be able to be loaded at any 4K aligned address below
    1G.  The technique used is to compile the decompressor with -fPIC and
    modify it so the decompressor is fully relocatable.  For the main
    kernel relocations are generated.  Resulting in a kernel that is relocatable
    with no runtime overhead and no need to modify the source code.
    
    A reserved 32bit word in the parameters has been assigned
    to serve as a stack so we figure out where are running.
