I'd say it can wait for 3.10

I'll rebase my patch on top of this one as your patch should be

Add generic wait_until_sent implementation which polls for empty
hardware buffers using the new port-operation tx_empty.
The generic implementation will be used for all sub-drivers that
implement tx_empty but does not define wait_until_sent.

Make sure to check ASYNC_INITIALISED before raising DTR when waking up
from blocked open in block_til_ready.
Currently DTR could get raised at hang up as a blocked process would
raise DTR unconditionally before checking for hang up and returning.

Add support for the at91sam9x5-family which must use the shadow
interrupt mask due to a hardware issue (causing RTC_IMR to always be
zero).

Move wake up of processes on blocked-open and modem-status wait queues
to after port shutdown at hangup.
This way the woken up processes can use the ASYNC_INITIALIZED flag to
detect port shutdown.
Note that this is the order currently used by serial-core.
