Subjectdrivers/scsi/megaraid/megaraid_sas_base.c:8458:21: 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: 9ebcfadb0610322ac537dd7aa5d9cbc2b2894c68
commit: 670d0a4b10704667765f7d18f7592993d02783aa sparse: use identifiers to define address spaces
date: 11 days ago
config: s390-randconfig-s031-20200629 (attached as .config)
compiler: s390-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: v0.6.2-3-gfa153962-dirty
git checkout 670d0a4b10704667765f7d18f7592993d02783aa
# save the attached .config to linux build tree
COMPILER_INSTALL_PATH=$HOME/0day COMPILER=gcc-9.3.0 make.cross C= CF='-fdiagnostic-prefix -D__CHECK_ENDIAN__' ARCH=s390

If you fix the issue, kindly add following tag as appropriate
