[PATCH] kexec: Export kexec_in_progress to modules

[Florian Fainelli]

The bcm_sf2 driver uses kexec_in_progress to know whether it can power
down an integrated PHY during shutdown, and can be built as a module.
Other modules may be using this in the future, so export it.

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

Eric, David, Stephen,

The offending commit is in David's net.git tree, so it would probably make
sense to route the fix through the same tree.

Thanks!
