RE: [patch V3 08/20] hexagon: Remove mm.h from asm/uaccess.h

Subject: [patch V3 08/20] hexagon: Remove mm.h from asm/uaccess.h

From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>

The defconfig compiles without linux/mm.h. With mm.h included the include
chain leands to:
|   CC      kernel/locking/percpu-rwsem.o
| In file included from include/linux/huge_mm.h:8,
|                  from include/linux/mm.h:567,
|                  from arch/hexagon/include/asm/uaccess.h:,
|                  from include/linux/uaccess.h:11,
|                  from include/linux/sched/task.h:11,
|                  from include/linux/sched/signal.h:9,
|                  from include/linux/rcuwait.h:6,
|                  from include/linux/percpu-rwsem.h:8,
|                  from kernel/locking/percpu-rwsem.c:6:
| include/linux/fs.h:1422:29: error: array type has incomplete element type
'struct percpu_rw_semaphore'
|  1422 |  struct percpu_rw_semaphore rw_sem[SB_FREEZE_LEVELS];

once rcuwait.h includes linux/sched/signal.h.

Remove the linux/mm.h include.
