Hi Atish,
First bad commit (maybe != root cause):
tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: 9f29bd8b2e7132b409178d1367dae1813017bd0e
commit: e557793799c5a8406afb08aa170509619f7eac36 RISC-V: Fix maximum allowed phsyical memory for RV32
date: 6 days ago
config: riscv-randconfig-r002-20210122 (attached as .config)
compiler: clang version 12.0.0 (https://github.com/llvm/llvm-project bd3a387ee76f58caa0d7901f3f84e9bb3d006f27)
reproduce (this is a W=1 build):
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
