I was wrong, the energy_model.h does not cause this issue. The issue is
already present in v5.8-rc2 (where there is no this EM commit).
I have reproduced in v5.8-rc2 with the .config from original email.
When I've fix this error:
"error: implicit declaration of function 'cpu_logical_map'"
new one showed up:
./include/linux/topology.h:210:9: error: use of undeclared identifier
'__node_cpumask'
return cpumask_of_node(cpu_to_node(cpu));
^
another showed up:
./arch/mips/include/asm/mach-loongson64/topology.h:12:33: note: expanded
from macro 'cpumask_of_node'
#define cpumask_of_node(node) (&__node_cpumask[node])
Then after a fix, the next one:
In file included from ./include/net/checksum.h:22:
./arch/mips/include/asm/checksum.h:195:9: error: unsupported inline asm:
input with type 'unsigned long' matching output with type '__wsum' (aka
'unsigned int')
: "0" ((__force unsigned long)daddr),
Thomas, Jiaxun, Huacai are you aware of these issues? Maybe just this
randconfig triggers some awkward configuration?

Lukasz

It looks like the energy_model.h causes this include on mips then some
header is missing (probably smp.h from mips/asm).
I will try to reproduce it and propose a fix.

Hi Lukasz,
FYI, the error/warning still remains.
tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: 9123e3a74ec7b934a4a099e98af6a61c2f80bbf5
commit: 1bc138c622959979eb547be2d3bbc6442a5c80b0 PM / EM: add support for other devices than CPUs in Energy Model
date: 8 weeks ago
config: mips-randconfig-r001-20200817 (attached as .config)
compiler: clang version 12.0.0 (https://github.com/llvm/llvm-project ab9fc8bae805c785066779e76e7846aabad5609e)
reproduce (this is a W=1 build):
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
# install mips cross compiling tool for clang build
# apt-get install binutils-mips-linux-gnu
git checkout 1bc138c622959979eb547be2d3bbc6442a5c80b0
# save the attached .config to linux build tree
