After merging the net tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:

ERROR: "kexec_in_progress" [drivers/net/dsa/bcm_sf2.ko] undefined!

Caused by commit

  2399d6143f85 ("net: dsa: bcm_sf2: Prevent GPHY shutdown for kexec'd kernels")

I used the version of the net tree from next-20161020 for today.  

OK, seems like we need an ifdef CONFIG_KEXEC_CORE, let me fix that.
Thanks Stephen!  

Stephen, can you send me the .config file? I could not reproduce it with
next-20161020 and doing a make multi_v7_defconfig:

This only started with the net tree as of today (HEAD a681574c99be).
The problem is simply that kexec_in_progress is not exported to modules.

Sorry, getting the actual .config file is a pain at this point since my
builds have moved on.

It probably had (the current .config has):

CONFIG_NET_DSA_BCM_SF2=m
CONFIG_KEXEC_CORE=y

If CONFIG_KEXEC_CORE is not set, then kexec_in_progress is defined to false.
