Subject: [PATCH mm-unstable v4 0/3] mm, printk: introduce new format for page_type

RFC v3:
   https://lore.kernel.org/lkml/20221218101901.373450-1-42.hyeyoo@gmail.com

This series was originally part of "move PG_slab to page_type" series,
but printk format implementation for page_type is separated to this series.

RFC v3 -> v4:
  - dropped patch 1 ("mm/hwpoison: remove MF_MSG_SLAB from action_page_types")
    and patch 2 ("mm: move PG_slab flag to page_type") from previous
    spin as they are planned as separate series

  - adjusted comments from Andy Shevchenko [1] and Petr Mladek [2]

  - added patch 1 ("mmflags.h: use less error prone method to define pageflag_names")
    for consistency with patch 2 ("mm, printk: introduce new format %pGt for page_type"),
    as suggested by Andy Shevchenko [1]

[2] https://lore.kernel.org/lkml/Y6HSutM8pmoKxQWp@alley/

Based on mm-unstable (ede43f2956cc "kasan: fix Oops due to missing calls
to kasan_arch_is_rea()") as there are recent changes in mmflags.h.

Hyeonggon Yoo (3):
  mmflags.h: use less error prone method to define pageflag_names
  mm, printk: introduce new format %pGt for page_type
  mm/debug: use %pGt to display page_type in dump_page()
