commit: 6f7eb520c385d6b7b97a136376296ec475b0d48b [991/1124] lib/mpi: Fix building for
powerpc with clang
config: powerpc-randconfig-r021-20200517 (attached as .config)
compiler: clang version 11.0.0 (https://github.com/llvm/llvm-project
13d44b2a0c7ef404b13b16644765977cd5310fe2)
reproduce:
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O
~/bin/make.cross
chmod +x ~/bin/make.cross
# install powerpc cross compiling tool for clang build
# apt-get install binutils-powerpc-linux-gnu
git checkout 6f7eb520c385d6b7b97a136376296ec475b0d48b
# save the attached .config to linux build tree
COMPILER_INSTALL_PATH=$HOME/0day COMPILER=clang make.cross ARCH=powerpc

All error/warnings (new ones prefixed by >>, old ones prefixed by <<):
> WARNING: vmlinux.o(.text+0x3a1f0): Section mismatch in reference
from the function ppc47x_pin_tlb() to the function .init.text:ppc47x_find_free_bolted()
The function ppc47x_pin_tlb() references
the function __init ppc47x_find_free_bolted().
This is often because ppc47x_pin_tlb lacks a __init
annotation or the annotation of ppc47x_find_free_bolted is wrong.
