I focused on other subthreads but I've read it now through. It has been
waiting in the queue. Can't do everything simultaneously. I did skim
each message as they came for this one though.

The main reason skimming was that I was thinking that perhaps Sean might
send a patch for this one and I would then read the thread again in
better detail and check that the patch matches the conclusions, as he
has been more active on this one.

Anyway, now that I've read it through in detail, I did just change the
init simply as:

secs_addr = sgx_get_epc_addr(encl->secs.epc_page);

ret = __einit(sigstruct, token, secs_addr);

I use a local for address to make the code more readable instead of
calling sgx_get_epc_addr() inside __einit().
