alloc_contig_range() worked at MAX_ORDER_NR_PAGES granularity to avoid
merging pageblocks with different migratetypes. It might unnecessarily
convert extra pageblocks at the beginning and at the end of the range.
Change alloc_contig_range() to work at pageblock granularity.
Special handling is needed for free pages and in-use pages across the
boundaries of the range specified by alloc_contig_range(). Because these=
Partially isolated pages causes free page accounting issues. The free
pages will be split and freed into separate migratetype lists; the in-use=
Pages will be migrated then the freed pages will be handled in the
aforementioned way.
