[PATCH] termios: Enable new style termios ioctls on x86-64
This turns on the split input/output speed features and arbitary baud rate
handling for the x86-64 platform. Nothing should break if you use existing
standard speeds. If you use the new speed stuff then you may see some
drivers failing to report the speed changes properly in error cases. This
will be worked on further. For the working cases this all seems happy.
I'll post a test suite used to test the basic stuff as well.
Patches for i386 will follow when I get a moment but are basically the
same. If people could patch/test-suite other architectures and submit them
that would be great.
