If you fix the issue, kindly add following tag as appropriate
Reported-by: kernel test robot <lkp@xxxxxxxxx>
All warnings (new ones prefixed by >>):
arch/powerpc/mm/book3s64/slice.c: In function 'slice_get_unmapped_area':
arch/powerpc/mm/book3s64/slice.c:639:1: warning: the frame size of 1040 bytes is larger than 1024 bytes [-Wframe-larger-than=]

The problem was already existing when slice.c was in arch/powerpc/mm/
This patch doesn't introduce the problem.
