s390 "ld.lld: error: section ... virtual address range overlaps with ..."

When attempting to build ARCH=s390 defconfig with ld.lld (available after llvm/llvm-project@fe3406e) after applying the patches for #1991, #1992, and #1993, there are a series of errors around overlapping virtual address ranges:

$ make -skj"$(nproc)" ARCH=s390 LLVM=1 OBJCOPY=s390x-linux-gnu-objcopy OBJDUMP=s390x-linux-gnu-objdump mrproper defconfig all

This is due to orphan section placement differences between GNU ld and LLD. Patch series to address this fully submitted and accepted: https://git.kernel.org/s390/l/acb7c202baa76235ed478043809366e7de1741c2
