What are your plans for 2.6.33?

The merge window is upon us, which by strict rules means that anything
not already in libata-dev.git#upstream needs to wait until 2.6.34.

However, bug fixes and the like should definitely be in 2.6.33.
->init_host is definitely 2.6.34 material. Some of the other stuff
could go either way.
