[AMDGPU][OBJTOOL] Two new objtool warnings in AMDGPU

[ms178]

I see these two objtool warnings nowadays with Clang-20 git (c660b281b60085cbe40d73d692badd43d7708d20) on CachyOS with Kernel 6.12.6.

drivers/gpu/drm/amd/amdgpu/amdgpu.o: warning: objtool: .text.dc_fixpt_recip: unexpected end of section
drivers/gpu/drm/amd/amdgpu/amdgpu.o: warning: objtool: .text.spl_fixpt_recip: unexpected end of section

This was brought up recently on LKML: https://lore.kernel.org/4bace457-cc26-13a3-bc90-ad6ad12bc2ed@loongson.cn/

As that was discussed in the context of the Loongson architecture, I've missed that, sorry. As I am compiling on Raptor Lake, thes warnings are definetly not arch-specific.

No worries! You are correct about them being architecture agnostic. I posted some thoughts after Peter brought me in, including the offending commit from LLVM (which I do not necessarily think is incorrect): https://lore.kernel.org/20241220223403.GA2605890@ax162/
