This one has been breaking my linux-next build for the past week.  I'm
not sure what's going on.  I build with a script:

make allmodconfig

cat << EOF >> .config
CONFIG_DYNAMIC_DEBUG=n
CONFIG_DEBUG_STRICT_USER_COPY_CHECKS=n
CONFIG_DYNAMIC_DEBUG=y
EOF

make oldconfig

Here are the errors:

  CHK     include/generated/compile.h
