The userland visible page flags (KPF_*) were initially moved to include/linux/kernel-page-flags.h in commit1a9b5b7fe0("mm: export stable page flags"), and later moved to include/uapi/linux/kernel-page-flags.h in commit607ca46e97("UAPI: (Scripted) Disintegrate include/linux"). Update the doc to reflect the current location of these flags. The member @walk_end of struct pm_scan_arg {} was wrongly written as "end_walk". The first sample code of the PAGEMAP_SCAN ioctl wrongly used the PM_SCAN_CHECK_WPASYNC flag twice, instead of the PM_SCAN_WP_MATCHING flag. The second one included the wrong category in the required mask - PAGE_IS_FILE should be used instead of PAGE_IS_SWAPPED as per the intention. Fix them all together.
