commit: 5d64f9bbb6281a5a89a2266b9d39daa1fca1d6b4 [243/250] amdgpu/pm: Implement new API function "emit" that accepts buffer base and write offset

reproduce (this is a W=1 build):
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
git remote add agd5f https://gitlab.freedesktop.org/agd5f/linux.git
git fetch --no-tags agd5f drm-next
git checkout 5d64f9bbb6281a5a89a2266b9d39daa1fca1d6b4
# save the config file to linux build tree
mkdir build_dir
