Subjectdrivers/video/fbdev/aty/atyfb_base.c:3461:2: error: implicit declaration of function 'ioremap_uc'
Hi Luis,

FYI, the error/warning still remains.

tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: 67944024c1cdd897e49a09b0d6af3ea38d1388ca
commit: 3cc2dac5be3f23414a4efdee0b26d79bed297cac drivers/video/fbdev/atyfb: Replace MTRR UC hole with strong UC
date: 8 months ago
config: ia64-allyesconfig (attached as .config)
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 3cc2dac5be3f23414a4efdee0b26d79bed297cac
# save the attached .config to linux build tree
make.cross ARCH=ia64

All errors (new ones prefixed by >>):
