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?
