On a system where system memory (according e820) is not covered by mtrr, mtrr_trim_memory converts a portion of memory to reserved, but bootloader has already put the initrd in that range. Thus, we need to have 64bit to use relocate_initrd too. [ Impact: fix using initrd when mtrr_trim_memory happen ] Signed-off-by: NYinghai Lu <yinghai@kernel.org> Signed-off-by: NH.
