Hi all, this series first cleans up the exec code and then adds proper kernel_execveat and kernel_wait callers instead of relying on the fact that the early init code and kernel threads implicitly run with the address limit set to KERNEL_DS. Note that the cleanup removes the compat execve(at) handlers (almost) entirely, as we can handle the compat difference very nicely in a unified codebase. The only exception is x86 where this would list the handlers twice in the same syscall table due to the messed up x32 design. I had to add an extra compat handler just for that case, but maybe someone has a better idea.
