Subjectvgacon.c:undefined reference to `screen_info'
Hi Chen,

It's probably a bug fix that unveils the link errors.

tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: 1001354ca34179f3db924eb66672442a173147dc
commit: f69405ce6c0fc9f4a039011007371b31f80b470d openrisc: include: asm: Kbuild: add default "vga.h"
date: 2 years, 11 months ago
config: openrisc-alldefconfig (attached as .config)
compiler: or32-linux-gcc (GCC) 4.5.1-or32-1.0rc1
reproduce:
wget https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/plain/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
git checkout f69405ce6c0fc9f4a039011007371b31f80b470d
# save the attached .config to linux build tree
make.cross ARCH=openrisc
