Subjectarch/powerpc/math-emu/lfs.c:23:32: sparse: sparse: incorrect type in argument 2 (different address spaces)
tree:   https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: bfe91da29bfad9941d5d703d45e29f0812a20724
commit: 670d0a4b10704667765f7d18f7592993d02783aa sparse: use identifiers to define address spaces
date: 3 weeks ago
config: powerpc-randconfig-s031-20200707 (attached as .config)
compiler: powerpc-linux-gcc (GCC) 9.3.0
reproduce:
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
# apt-get install sparse
# sparse version: v0.6.2-31-gabbfd661-dirty
git checkout 670d0a4b10704667765f7d18f7592993d02783aa
# save the attached .config to linux build tree
