[RFC] powerpc/mm/pgtable: Split mappings on hot-unplug

This patch splits the a linear mapping if the hot-unplug range is smaller than the mapping size. The code detects if the mapping needs to be split into a smaller size and if so, uses the stop machine infrastructure to map the current linear mapping with a smaller size mapping. Then the requested
