Here's my two step plan.

1. Let's ack this with the cosmetic changes. It's good first baby
step to take.
2. I'll do another patch that wipes sgx_epc_section.

Both are functionally self-contained patch that improve. That's why
I don't see point in iterating them as a two patch patch set. One
patch at a time is less overhead.
