Subject: arch/sh/kernel/process_32.c:42:9: sparse: sparse: incorrect type in
argument 1 (different base types)
Hi Luc,
First bad commit (maybe != root cause):
tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: c2dc4c073fb71b50904493657a7622b481b346e3
commit: e5fc436f06eef54ef512ea55a9db8eb9f2e76959 sparse: use static inline for __chk_{user,io}_ptr()
date: 9 weeks ago
config: sh-randconfig-s032-20201030 (attached as .config)
compiler: sh4-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: v0.6.3-68-g49c98aa3-dirty
# https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=e5fc436f06eef54ef512ea55a9db8eb9f2e76959
git remote add linus https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
git fetch --no-tags linus master
git checkout e5fc436f06eef54ef512ea55a9db8eb9f2e76959
# save the attached .config to linux build tree
