[Patch v3 0/2] mm/pageblock: improve readability of some pageblock handling

[Wei Yang <richard.weiyang@gmail.com>]

During code reading, found two possible points to improve the readability of
pageblock handling.

Patch 1: isolate bit is standalone and there are dedicated helpers. Instead of
check the bit directly, we could use the helper to do it.

Patch 2: remove PB_migratetype_bits and PB_migrate_end to reduce magical
computation.

v2->v3:
    fix the definition of MIGRATETYPE_MASK, thanks ziy

v1->v2:
    remove PB_migratetype_bits and PB_migrate_end

Wei Yang (2):
  mm/page_alloc: use xxx_pageblock_isolate() for better reading
  mm/pageblock-flags: remove PB_migratetype_bits/PB_migrate_end
