Why not simply

What's with that guy? Left here as documentation showing what's at 3*8
offset?

Those are in ...uapi/asm/sgx.h too. Unify?

TSC
I can see why you would write "TCS" though - there's a thread control
structure thing too in that patch.

I've been wondering what that "@e" thing is and I believe I've found it at the
end: "... @e, the optional sgx_enclave_exception struct"
Yes?
Please rewrite what that "e" is here - I think you wanna say "struct
sgx_enclave_run.exception" instead to clarify.

Are all those defines being added to the uapi header, also actually
needed by userspace?

I'm sure you can avoid that "at the time of enclave exit" repetition.
