The commit only moves code around with one additional observable change:
the hotplug.c was compiled with custom CFLAGS (-march=armv7-a). These

This turns out to be wrong, and your change broke 'allmodconfig' builds
in linux-next. Please apply this patch on top.

Arnd, Krzysztof commented its fix has been submitted and landed in my -test tree not -next because it should be handled in rmk's tree I think.

I sent the patch to RMK patch tracking system just now and it should be fine in there.

BTW, I just applied the fix in my -next until its ladning in RMK tree but as you know it will be not be sent to arm-soc via samsung tree...

One more, Arnd please pull my pull-request 2nd round and 3rd round for samsung stuff for 3.18.

My patch definitely needed more testing.
I posted a fix here:
However it seems that it wasn't picked up by anyone yet.

Russell, could you pick up the patch (with acks from Nicolas and Kukjin)?

I believe Russell will take the patch in his tree.
