size-preserving integer to pointer cast
Hi Rasmus,
First bad commit (maybe != root cause):
tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: 2ac69819ba9e3d8d550bb5d2d2df74848e556812
commit: 5a35435ef4e6e4bd2aabd6706b146b298a9cffe5 soc: fsl: qe: remove PPC32 dependency from CONFIG_QUICC_ENGINE
date: 9 months ago
config: powerpc-randconfig-s032-20200826 (attached as .config)
compiler: powerpc64-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: v0.6.2-191-g10164920-dirty
git checkout 5a35435ef4e6e4bd2aabd6706b146b298a9cffe5
# save the attached .config to linux build tree
COMPILER_INSTALL_PATH=$HOME/0day COMPILER=gcc-9.3.0 make.cross C=1 CF='-fdiagnostic-prefix -D__CHECK_ENDIAN__' ARCH=powerpc
If you fix the issue, kindly add following tag as appropriate
