Conversely I don't think it's acceptable for -stable to merge a change that replaces one known bug with another; it violates our rule #2: - It must be obviously correct and tested. If you care about support for building with Clang, then please either fix your fix or fix the compiler to handle `-msym32' or an equivalent option (which seems a good idea for n64 MIPS performance anyway -- you're wasting a lot of cycles to explicitly put the sign-extension of bit 31 into the high order 32 bits where the CPU architecture does it for you already). And only then offer a backport of whatever you feel is needed to -stable. Maciej
