[Intel-gfx] [drm-tip:drm-tip 15/1373] arch/frv/include/asm/pgalloc.h:48:2: error: implicit declaration of function 'pgtable_page_dtor'; did you mean 'pgdat_page_nr'?

[Oded Gabbay]

Hi,
There is a missing #include <linux/mm.h> at amdgpu_amdkfd.h
I'll send a patch to Dave to apply to his drm-next tree to fix this.
Thanks for catching this,
Oded
