Subject: linux-next: build failure after merge of the userns tree

Hi all,
After merging the userns tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:
kernel/sched/fair.c: In function 'init_numa_balancing':
kernel/sched/fair.c:2884:9: error: implicit declaration of function 'init_task_work'; did you mean 'init_irq_work'? [-Werror=implicit-function-declaration]
2884 | init_task_work(&p->numa_work, task_numa_work);
| ^~~~~~~~~~~~~~
| init_irq_work
kernel/sched/fair.c: In function 'task_tick_numa':
kernel/sched/fair.c:2935:25: error: implicit declaration of function 'task_work_add' [-Werror=implicit-function-declaration]
2935 | task_work_add(curr, work, TWA_RESUME);
| ^~~~~~~~~~~~~
kernel/sched/fair.c:2935:51: error: 'TWA_RESUME' undeclared (first use in this function)
2935 | task_work_add(curr, work, TWA_RESUME);
| ^~~~~~~~~~
Maybe caused by commit
03248addadf1 ("resume_user_mode: Move to resume_user_mode.h")
or
8ca07e17c9dd ("task_work: Remove unnecessary include from posix_timers.h")
interacting with (maybe) commit
c4ad6fcb67c4 ("sched/headers: Reorganize, clean up and optimize kernel/sched/fair.c dependencies")
from the tip tree.
I have applied this merge fix patch.
