[PATCH] tty: Revised diff for the i386/x86_64 arbitary speedsupport

From: Alan Cox
Date: Thu Mar 08 2007 - 10:46:19 EST


Adding some more test cases found a bug in the definition of IBSHIFT. At
the moment we have no hardware support for split baud rates but this
showed up once I did testing of that...

Replaces the previous diff.
