Hi all,
After merging the mm tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

Caused by commit
8e53757638ec ("err.h: add ERR_PTR_PCPU(), PTR_ERR_PCPU() and IS_ERR_PCPU() functions")
Does include/linux/err.h really need to include asm/percpu.h? __percpu is
defined in compiler_types.h which is included in every c code compile.
I have reverted that commit and the following one for today.
