Subject: [PATCH] CRIS v10: Include mm.h instead of vmstat.h in kernel/time.c

Commit 2f569afd9ced9ebec9a6eb3dbf6f83429be0a7b4
(CONFIG_HIGHPTE vs. sub-page page tables) introduced use of
inc_zone_page_state and dec_zone_page_state in include/linux/mm.h.

Those are defined in include/linux/vmstat.h, but after it includes
mm.h, making it impossible to include vmstat.h since inc_zone_page_state
and dec_zone_page_state then would be undefined.

arch/cris/arch-v10/kernel/time.c does just this, which makes the
CRIS v10 build break with the following error:

...
  CC      arch/cris/arch-v10/kernel/time.o

                 from arch/cris/arch-v10/kernel/time.c:17:

make[1]: *** [arch/cris/arch-v10/kernel] Error 2

...

By changing kernel/time.c to include linux/mm.h, the build succeeds.
