Very nice and short list now!

I've double-checked all calls and the only one I'm not sure about is
sys_sigaltstack. Did we discuss that one earlier?
My first guess would be that it's easier to use the compat
version of that.

I would probably also group sys_shmat with sys_openat, because it's
different from the other ones in the first block as this is not
about passing 64-bit arguments as registers, but instead it's about
the behavior of the system call.
