There are a number of different views to how much memory is currently active. There is the arch-independent zone-sizing view, the bootmem allocator and memory models view. Architectures register this information at different times and is not necessarily in sync particularly with respect to some SPARSEMEM limitations. This patch introduces mminit_validate_memmodel_limits() which is able to validate and correct PFN ranges with respect to the memory model. It is only SPARSEMEM that currently validates itself.
