Hm, ok then.
You can find the patch here:
I pushed it here:
The idea is to:
1. Revert the original, incorrect changes to InnoDB mutex, make them be
unchanged on i386/amd64 compared to 5.5.39.
2. Add the missing full barriers in InnoDB mutex for PowerPC so the code works
similarly as on i386/amd64.
Feel free to use it or not, or modify it as you see fit.
