[PATCH 0/2] kho: fix bootmem sizing

["Mike Rapoport (Microsoft)" <rppt@kernel.org>]

There were several reports about issues with KHO bootmem sizing.

The bootmem areas are sized from overlapping views of the memory reserved
in memblock, so on NUMA systems memory allocated on a node is accounted
twice and with CONFIG_NUMA=n the lowmem and the global areas are accounted
once again in the area of node 0. Besides, the lowmem and the global areas
are reserved even when they are empty.

The first patch skips empty bootmem areas and the second one makes the
lowmem, per-node and global areas cover separate parts of the reserved
memory.
