Subject: [PATCH] kexec: Export kexec_in_progress to modules

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")
Signed-off-by: Florian Fainelli <f.fainelli@...il.com>

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!
