Hi Linus,

After merging the gpio tree, today's linux-next build (x86_64
allmodconfig) failed like this:

Exposed by commit

  5df7fd46b70b ("pio/qoriq: Add qoriq platforms support")

The COMPILE_TEST dependency has revealed several implicit includes ...

I have used the gpio tree from next-20160128 for today.
