…dule delayed work

On my test:
platform:rk3326
step by step:
1.poweron
2.evtest /dev/input/event3 # because on my board event3 is headset input event node
3.test press & release button on headset
4.evtest could output EV_KEY & code value and other infos
5.echo mem > /sys/power/state # make board system suspend
6.press power button to make board resume
7.retry 3th step
8.evtest couldn.t output anything, but replug headset could make evtest output back
to normal.
Therefore:
add judge headset state when system resume after suspend

selftests/bpf: Test bpf_mprog query API via libbpf and raw syscall
f9b0879 
Add a new test case which performs double query of the bpf_mprog through
libbpf API, but also via raw bpf(2) syscall. This is testing to gather
first the count and then in a subsequent probe the full information with
the program array without clearing passed structs in between.

Add a new test case to query on an empty bpf_mprog and pass the revision

succeed.

mm/vmscan: fix a bug calling wakeup_kswapd() with a wrong zone index
d6159bd 
[ Upstream commit 2774f25 ]

With numa balancing on, when a numa system is running where a numa node
doesn't have its local memory so it has no managed zones, the following
oops has been observed.  It's because wakeup_kswapd() is called with a
wrong zone index, -1.  Fixed it by checking the index before calling
wakeup_kswapd().
