Hi Ingo,

Today's linux-next build (x86_64 allmodconfig) failed like this:

arch/x86/mm/kmmio.c: In function 'get_kmmio_probe':
arch/x86/mm/kmmio.c:85: error: implicit declaration of function 'list_for_each_entry_rcu'
arch/x86/mm/kmmio.c:85: error: 'list' undeclared (first use in this function)
arch/x86/mm/kmmio.c:85: error: (Each undeclared identifier is reported only once
arch/x86/mm/kmmio.c:85: error: for each function it appears in.)
arch/x86/mm/kmmio.c:85: error: syntax error before '{' token
arch/x86/mm/kmmio.c:88: warning: no return statement in function returning non-void
arch/x86/mm/kmmio.c: In function 'get_kmmio_fault_page':
arch/x86/mm/kmmio.c:100: error: 'list' undeclared (first use in this function)
arch/x86/mm/kmmio.c:100: error: syntax error before '{' token
arch/x86/mm/kmmio.c:103: warning: no return statement in function returning non-void
arch/x86/mm/kmmio.c: In function 'add_kmmio_fault_page':
arch/x86/mm/kmmio.c:328: error: implicit declaration of function 'list_add_rcu'
arch/x86/mm/kmmio.c: In function 'remove_kmmio_fault_pages':
arch/x86/mm/kmmio.c:420: error: implicit declaration of function 'list_del_rcu'

This is caused by the merge with the sched tree which contains the
ruclist split.

I applied the patch below.
