Merge remote-tracking branch 'mst/tags/for_anthony' into staging

pc last minute fixes for 1.8

This has a patch that drops an unused FW CFG entry.
I think it's best to include it before 1.7 to avoid
the need to maintain it in compat machine types.

There's also a doc bugfix by Amos: I'm guessing
doc fixes are still fair game even at this late stage.
