I'm having a hard time understanding what the benefit of this series is, given that we only support EABI compat tasks. When adding a new compat system call, you can't just blindly hook it up without checking whether it needs a wrapper to deal with any type conversion etc, so really we're just replacing one table with another as far as I can tell. What am I missing? I also really don't think we should be generating the 32-bit UAPI headers from the 64-bit compat system call support (if that's what you're trying to do -- make headers_check fails with your patches applied). arch/arm/ is the canonical place for the 32-bit UAPI, and we're just implementing that.
