Hi all,

Building Linus' tree, today's linux-next build (x86_64 allmodcongig)
failed like this:

In file included from arch/x86/include/asm/atomic.h:5,
                 from include/linux/atomic.h:7,
                 from include/linux/llist.h:51,
                 from include/linux/irq_work.h:5,
                 from kernel/smp.c:10:

Caused by me starting to build with various GCC_PLUGIN config options set.

I have cherry-picked commit

  bfb9fbe0f7e7 ("sched: Fix RANDSTRUCT build fail")

from the tip tree until it is sent upstream to Linus.
