Subjectinclude/linux/unaligned/access_ok.h:7:19: error: redefinition of 'get_unaligned_le16'
Hi Vincent,

FYI, the error/warning still remains.

tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: 045169816b31b10faed984b01c390db1b32ee4c1
commit: 3194c6870158e305dac2af52f83681e9cb67280f NFC: nfcmrvl: add firmware download support
date: 1 year, 2 months ago
config: ia64-allyesconfig (attached as .config)
compiler: ia64-linux-gcc (GCC) 6.2.0
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 3194c6870158e305dac2af52f83681e9cb67280f
# save the attached .config to linux build tree
make.cross ARCH=ia64
