mm: introduce dump_page() and print symbolic flag names
- introduce dump_page() to print the page info for debugging some error
condition.
- convert three mm users: bad_page(), print_bad_pte() and memory offline
failure.
- print an extra field: the symbolic names of page->flags
Example dump_page() output:
[ 157.521694] page:ffffea0000a7cba8 count:2 mapcount:1 mapping:ffff88001c901791 index:0x147
[ 157.525570] page flags: 0x100000000100068(uptodate|lru|active|swapbacked)
