I'm not sure what lld is saying here. It seems this problem has always been
there, the revert commit just made it appears more.
These errors should still be investigated, but I think the revert commit is
fine.
I see CONFIG_CMODEL_MEDLOW=y, so probably has something to do with
arch/riscv/mm/init.c is compiled with -mcmodel=medany, while the others are
compiled with -mcmodel=medlow. I leave it to smarter minds..

Ya, I agree.

LLVM has a blurb that says
// Linking object files with different code models is undefined behavior
// because the compiler would have to generate additional code (to span
// longer jumps) if a larger code model is used with a smaller one.
// Therefore we will treat attempts to mix code models as an error.
which is just wacky, so I'm moaning about it over here
