The "new" warning is just the "skipping duplicate warning", which was
already merged with commit 0a7fb6f07e3a ("objtool: Increase per-function
WARN_FUNC() rate limit"). So none of the warnings are specific to this
pull request.

Tiezhu, can you please look at this warning?

arch/loongarch/kernel/traps.o: warning: objtool: show_stack+0xe0: stack state mismatch: reg1[22]=-1+0 reg2[22]=-2-160
arch/loongarch/kernel/traps.o: warning: objtool: show_stack+0xe0: stack state mismatch: reg1[23]=-1+0 reg2[23]=-2-152
