Re: [PATCH 16/35] x86: make 64 bit use early_res instead of bootmem before slab

[Yinghai Lu <yinghai@kernel.org>]

please check

Subject: [PATCH] x86: nobootmem fix compiling on power pc

Stephen Rothwell reported: on powerpc

x86: make 64 bit use early_res instead of bootmem before slab

cause

mm/page_alloc.c:3468: error: implicit declaration of function 'find_early_area'
mm/page_alloc.c:3483: error: implicit declaration of function 'reserve_early_without_check'

actually the function is only needed for no_bootmem
