I wasn't able to finish everything this morning (not even close). The
vDSO code and documentation was in rough shape. I finished cleaning it
up, but still need to test and rewrite the changelog.

If you really want to send v23 this weekend I can work more tonight
and/or tomorrow morning. My preference would be to just punt a few more
days.

My todo list for v23:

- Test vDSO changes and craft proper patches
- Rewrite vDSO changelog
- Rewrite vDSO exception fixup changelog
- Implement multi-page EADD

My todo list post-v23:
- Write SGX programming model documentation (requested by Casey)
