Subjectdrivers/edac/amd64_edac.c:3065:47: sparse: sparse: incorrect type in argument 3 (different address spaces)
tree:   https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: fb893de323e2d39f7a1f6df425703a2edbdf56ea
commit: 670d0a4b10704667765f7d18f7592993d02783aa sparse: use identifiers to define address spaces
date: 8 weeks ago
config: i386-randconfig-s001-20200812 (attached as .config)
compiler: gcc-9 (Debian 9.3.0-15) 9.3.0
reproduce:
# apt-get install sparse
# sparse version: v0.6.2-168-g9554805c-dirty
git checkout 670d0a4b10704667765f7d18f7592993d02783aa
# save the attached .config to linux build tree
make W=1 C=1 CF='-fdiagnostic-prefix -D__CHECK_ENDIAN__' ARCH=i386
