Changes from 1.1.40 to 1.1.41

These changes are archived on ftp.crynwr.com:pub/kchanges and http://www.crynwr.com/kchanges. I cannot answer questions about Linux -- I merely summarize the kernel patches after reading them. I try to make them useful to everyone, but kernel hackers should take them with a grain of salt and read the patches themselves. The patch file is patch41.gz

• 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.
• Seemingly gratuitious change to line discpline code (call put_char instead of write).
• Run a pty at "38400 bps" instead of "9600 bps".
• Serial ports have a temporary buffer for writing (saves memory when we need it most).
• Serial driver doesn't force driver to be stopped just because the ASYNC is closing.
• Serial driver keeps more error-tracking information.
• Sometimes we can get a serial xmit_cnt that is less than zero.
• 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.
• Moved assembly language string functions to /usr/include/linux/i386/string.h from /usr/include/linux/string.h.
• Removed some assembly language from vsprintf.
