This is acting up on Debian's 32-bit architectures, namely i386, armel
and armhf:

The diff is the same on all architectures.
-14 seems to be -EFAULT, and move_pages(2) says:
Page states in the status array
The following values can be returned in each element of the status array.
-EFAULT
This is a zero page or the memory area is not mapped by the process.
