[Nishanth Menon]

Hi,
Not sure if this was already reported (but searching linux-arm and 
linux-next MLs did not quickly show something)

* master 7ce7d89f4883 Linux 4.10-rc1
-> http://pastebin.ubuntu.com/23689404/

Backtracking:
next-20161224, next-20161223, next-20161222-> 
http://pastebin.ubuntu.com/23689415/ (different from master)

next-20161221 -> Builds fine (last clean build)

GCC:
