Subject: proc: fix kflags to uflags copying in /proc/kpageflags
From: Wu Fengguang <fengguang.wu@xxxxxxxxx>
Fix kpf_copy_bit(src,dst) to be kpf_copy_bit(dst,src) to match the actual
call patterns, e.g. kpf_copy_bit(kflags, KPF_LOCKED, PG_locked).
This misplacement of src/dst only affected reporting of PG_writeback,
PG_reclaim and PG_buddy. For others kflags==uflags so not affected.
