Subject: [PATCH] x86: fix bootmem with non numa after early_res change

Ingo found early_res replacing bootmem code broke original bootmem code for non numa
it crashes during early bootup with:

[ 0.000000] #8 [0000012000 - 000001a000] BOOTMAP ==> [0000012000 - 000001a000]

it turns out that one line should not be deleted...

need to be folded into
