I try to make them useful to everyone, but kernel hackers should take them with a grain of salt and read the patches themselves. Floppy driver extensively changed. Support added for two floppy disk controllers and FIFO bug fixing on ED disks. If a hard disk delay is needed, it's done more reliably.
Serial driver keeps more error-tracking information.
If the irq is set to zero, the serial port doesn't generate interrupts. Fixed a serial race condition related to have a large amount to transmit. Added flag options for termios setting behavior. Catch a few missed read-only block device checks. Removed some assembly language from vsprintf.
