Subject: Upping baud rate for ttyS0

I've downloaded the source RPM for the 3.10 kernel. I'm looking for the 
driver code that I need to modify to support higher baud rates than that 
permitted by the current serial driver (B115200 when using stty or 
cfsetispeed() + tcsetattr()).

I've looked in the drivers/tty/serial/ source files but am uncertain 
where to begin.

Any pointer would be appreciated.
