Message-ID<qTfP5-x3-27@gated-at.bofh.it>
Hi Andrew,

After merging the akpm-current tree, today's linux-next build (arm
efm32_defconfig) failed like this:

fs/proc/task_nommu.c:132:28: error: 'mm' undeclared (first use in this function)

Caused by commit

  e87d4fd02f40 ("proc: revert /proc/<pid>/maps [stack:TID] annotation")

# CONFIG_MMU is not set

Discovered after today's linux-next release.

Thanks, I have added that to the akpm-current tree for tomorrow in case
Andrew does not get around to it.

Adding that will uncover one more build failure, and the patch for that
is at:
