commit: 95db8d6001df8966e3370a66c9f358925fbcc890 [21/42] drm/amdgpu: replace get_user_pages with HMM mirror helpers
config: mips-allyesconfig (attached as .config)
compiler: mips-linux-gnu-gcc (Debian 7.2.0-11) 7.2.0
reproduce:
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
git checkout 95db8d6001df8966e3370a66c9f358925fbcc890

Note: the radeon-alex/drm-next-5.2-wip HEAD 5666aea3ea494d4dd96df8f092cab32dbeeac321 builds fine.
It only hurts bisectibility.

I think Philip fixed those issues on amd-staging-drm-next. Either some
fixes are missing on drm-next-5.2-wip, or they are there but should be
squashed to avoid hitting these errors on intermediate builds.

The fixes are there; they are the subsequent commits, I guess I can squash them in.
