Subject[PATCH 0/5] proc: export more page flags in /proc/kpageflags (take 4)
Hi all,

Export 9 more flags to end users (and more for kernel developers):

11. KPF_MMAP (pseudo flag) memory mapped page
12. KPF_ANON (pseudo flag) memory mapped page (anonymous)
13. KPF_SWAPCACHE page is in swap cache
14. KPF_SWAPBACKED page is swap/RAM backed
15. KPF_COMPOUND_HEAD (*)
16. KPF_COMPOUND_TAIL (*)
17. KPF_UNEVICTABLE page is in the unevictable LRU list
18. KPF_HWPOISON hardware detected corruption
19. KPF_NOPAGE (pseudo flag) no page frame at the address

(*) For compound pages, exporting _both_ head/tail info enables
users to tell where a compound page starts/ends, and its order.

Please check the documentary patch and changelog of the final patch
for the details.
