andrew,
please drop Johannes' patch : bootmem: avoid DMA32 zone by default
so you don't need to apply two fix patches from me:
[PATCH] early_res: double check with updated goal in alloc_memory_core_early
[PATCH] x86/bootmem: introduce bootmem_default_goal
move all bootmem to above 4g, make system performance get worse...
Thanks
Yinghai Lu
