TTY/Serial patches for 4.9-rc1

Here is the big TTY and Serial patch set for 4.9-rc1.

It also includes some drivers/dma/ changes, as those were needed by some
serial drivers, and they were all acked by the DMA maintainer. Also in
here is the long-suffering ACPI SPCR patchset, which was passed around
from maintainer to maintainer like a hot-potato. Seems I was the
sucker^Wlucky one. All of those patches have been acked by the various
subsystem maintainers as well.

All of this has been in linux-next with no reported issues.
