Subject: [PATCH] include: asm-generic: page.h: Remove useless get_user_page and free_user_page
They are not symmetric with each other, neither are used in real world
(can not be found by grep command in source code root directory), so
remove them.
Signed-off-by: Chen Gang <gang.chen.5i5j@xxxxxxxxx>
Compile and run tested on m68k (MMU and noMMU) targets.
No problems found. So for those parts:
Acked-by: Greg Ungerer <gerg@xxxxxxxxxxx>
Regards
Greg
