For example, this new warning in the arm multi_v7_defconfig build (I
did a test merge on top of the latest linux-next and some simple
builds):

arch/arm/kernel/traps.c: In function 'bad_syscall':
arch/arm/kernel/traps.c:508:22: warning: unused variable 'thread' [-Wunused-variable]
  struct thread_info *thread = current_thread_info();
                      ^

The merge produced no conflicts needing manual resolution.
