[PATCH 23/39] x86, lmb: Add x86 version of __lmb_find_area()
Generic version is going from high to low, and it seems it can not find right area compact enough. the x86 version will go from goal to limit and just like the way We used for early_res use ARCH_FIND_LMB_AREA to select from them. For 32 bit have to use CONFIG_ARCH_FIND_LMB_AREA=y, because some alloc_bootmem ... 9 Apr 2010 02:21
