Yinghai Lu 4ce7a8697c x86: revert wrong memblock current limit setting
Dave reported big numa system booting is broken.

It turns out that commit 5b6e529521 ("x86: memblock: set current limit
to max low memory address") sets the limit to low wrongly.

max_low_pfn_mapped is different from max_pfn_mapped.
max_low_pfn_mapped is always under 4G.

That will memblock_alloc_nid all go under 4G.

Revert 5b6e529521 to fix a no-boot regression which was triggered by
457ff1de2d ("lib/swiotlb.c: use memblock apis for early memory
allocations").
