argument 1 (different address spaces)
Hi Stephen,
First bad commit (maybe != root cause):
tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: f0fddcec6b6254b4b3611388786bbafb703ad257
commit: 1062fc45d1e93faefb93961f3be0a687f3f0e2e1 MIPS: Loongson64: Select SMP in Kconfig to avoid build error
date: 10 months ago
config: mips-randconfig-s031-20210724 (attached as .config)
compiler: mips64-linux-gcc (GCC) 10.3.0
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: v0.6.3-341-g8af24329-dirty
# https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=1062fc45d1e93faefb93961f3be0a687f3f0e2e1
git remote add linus https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
git fetch --no-tags linus master
git checkout 1062fc45d1e93faefb93961f3be0a687f3f0e2e1
# save the attached .config to linux build tree
