commit 1b9ae0c92925ac40489be526d67d0010d0724ce0 upstream.
When compiling inside the kernel include linux/stddef.h instead of stddef.h. When I compile this header file in backports for power PC I run into a conflict with ptrdiff_t. I was unable to reproduce this in mainline kernel. I still would like to fix this problem in the kernel.
