--- Comment #23 from Nick Desaulniers <ndesaulniers at google.com> ---
Ok, the relevant toolchain patches have landed.  To summarize, that's:

1. ARM: https://reviews.llvm.org/rG5c91b98c5d45243352bf10262454bcac77cd3fed
2. MIPS: https://reviews.llvm.org/rGc8c176d999d2c2166dee8d67c32b4f8f42b4f1bd
3. PPC: https://reviews.llvm.org/rGd8b6ae072d7734e2abadd54ecddfd6cb77b7e4c0
4. RISCV: https://reviews.llvm.org/rGe9b3f2573090a2fb9494975e4615f77b898e36a3
5. MIPS (__multi3):
https://reviews.llvm.org/rG6860b136b9e14e7c5771b710bea7370d5020a94b
6. https://reviews.llvm.org/rGd0eeb64be5848a7832d13db9d69904db281d02e8

Closing this as fixed.

Removing from release-13.0.0 blockers; these are too high risk IMO to try to
cherry pick all of these to the clang-13 release. I'd rather they had time to
soak for the clang-14 release.  We have to work around this in the kernel for
older clang releases that we still support anyways, and Renato and Craig agreed
with me on IRC.

Now onto the kernel workaround.
