This patch is for linux-6.3.y only, it has no direct mainline equivalent.
LLVM 17 will now use the GOT for extern weak symbols when using the medany model, which causes a linker orphan section warning on linux-6.3.y:
ld.lld: warning: <internal>:(.got) is being placed in '.got'
This is not an issue in mainline because handling of the .got section was added by commit 39b33072941f ("riscv: Introduce CONFIG_RELOCATABLE") and further extended by commit 26e7aacb83df ("riscv: Allow to downgrade paging mode from the command line") in 6.4-rc1. Neither of these changes are suitable for stable, so add explicit handling of the .got section in a standalone change to align 6.3 and mainline, which addresses the warning.
This is only an issue for 6.3 because commit f4b71bff8d85 ("riscv: select ARCH_WANT_LD_ORPHAN_WARN for !XIP_KERNEL") landed in 6.3-rc1, so earlier releases will not see this warning because it will not be enabled.
