Hi,

12.0-ALPHA8 #1 r339021, drm-devel-kmod 4.16.g20180927.

Trying to `kldload amdgpu` fails with:

anon_inodefs registered
debugfs registered
link_elf_obj: symbol __kfifo_in_r undefined
debugfs unregistered
anon_inodefs unregistered
Warning: memory type linux leaked memory on destroy (514 allocations, 
65680 bytes leaked).
linker_load_file: /boot/modules/amdgpu.ko - unsupported file type

kfifo_put() macro used in drivers/gpu/drm/amd/amdgpu/vega10_ih.c has the 
__kfifo_in_r, the prototype is declared in 
linuxkpi/gplv2/include/linux/kfifo.h, but the definition is nowhere to 
be found (guess the same is true for kfifo_get()).
