This is a note to let you know that I've just added the patch titled
serial: 8250: Enable 16550A variants by default on non-x86
to my tty git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git in the tty-next branch.
The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)
The patch will also be merged in the next major kernel release during the merge window.
If you have any questions about this process, please let me know.

Some embedded devices still use these serial ports; make sure they're still enabled by default on architectures more likely to have them, to avoid rendering someone's console unavailable.
