Thanks, Mike.

My thought on the patch 1/2 splitting is:
patch 1 is removing all relevant codes in mm, including the usage of
dma_reserve in free_area_init_core() and exporting set_dma_reserve()
to any ARCH which want to subtract the dma_reserve from DMA zone.

Patch 2 purely remove the code in x86 ARCH about how to get dma_reserve.

Your suggestion is also good to me, I can rearrange the order and
repost.
