commit: 32df1ea7b631ec2e37b4a3917829fb3c204cea9c [3/46] bvec: add memcpy_{from,to}_bvec
and memzero_bvec helper
config: mips-rb532_defconfig (attached as .config)
compiler: mipsel-linux-gcc (GCC) 9.3.0
reproduce (this is a W=1 build):
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O
~/bin/make.cross
chmod +x ~/bin/make.cross
git remote add hch-block git://git.infradead.org/users/hch/block.git
git fetch --no-tags hch-block bvec-kmap
git checkout 32df1ea7b631ec2e37b4a3917829fb3c204cea9c
# save the attached .config to linux build tree
