How about the following ? Seems to be less invasive, and it fixes the
immediate problem.

Subject: [PATCH] hexagon: Fix build error caused by include file order
hexagon builds fail with the following error message.
In file included from ./include/linux/memcontrol.h:30:0,
from ./include/linux/swap.h:8,
from ./arch/hexagon/include/asm/pgtable.h:27,
from ./include/linux/mm.h:70,
from arch/hexagon/kernel/asm-offsets.c:28:
./include/linux/vmstat.h: In function '__inc_zone_page_state':
./include/linux/vmstat.h:294:2: error:
implicit declaration of function 'page_zone'
Drop unnecessary includes from header files and add missing
includes to source files to fix the problem.
