This was introduced in kernel commit 8c2dd3e4a4b ("mm: rename
__alloc_page_frag to page_frag_alloc and __free_page_frag to
page_frag_free") and commit 44fdffd7050 ("mm: add support for releasing
multiple instances of a page") and is used by the mt76 driver.
Backporting it to kernel older than 4.2 is harder so just do it till
that version.

There is a typo in the timekeeping.h backport, fix that.
Additionally, fix the gfp.h file tha has a copy/paste issue where
__BACKPORT_TIMKEEPING_H is used instead of __BACKPORT_LINUX_GFP_H.

This was added to the mainline kernel in commit ac4f832eb2 "mm,
page_alloc: distinguish between being unable to sleep, unwilling to
sleep and avoiding waking kswapd". Instead of __GFP_KSWAPD_RECLAIM the
old mm code did not got any flag.
