It doesn't matter whether there is ADDU or DADDU anymore, given that
commit 198688edbf77 ("MIPS: Fix inline asm input/output type mismatch in
checksum.h used with Clang") has added a redundant 32-bit sign-extension
operation right afterwards, regressing size/performance by an extra
instruction in this performance-critical code as a workaround for a stupid
compiler.
I'm not sure though why the bot has been verifying old commit
c434b9f80b09 ("MIPS: Kconfig: add MIPS_GENERIC_KERNEL symbol") instead,
which predates the workaround. Perhaps current master also fails to build
in this file for one reason or another and bisection has misled the bot
into an unrelated commit?

Shouldn't this concern have been addressed by Tiezhu's follow up?

I guess it never got picked up?

Still it is a hack. I have now rewritten this code in plain C instead.
