Please avoid the completely unreadably long line. i.e.
int isolate_single_pageblock(unsigned long boundary_pfn, gfp_t gfp_flags,

alloc_contig_range() worked at MAX_ORDER-1 granularity to avoid merging
pageblocks with different migratetypes. It might unnecessarily convert

alloc_contig_range() to work at pageblock granularity.
