Changes from 1.1.25 to 1.1.26

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 patch26.gz

• In config.in, don't include AT1500 support by default, and do include NE2000 support by default.
• Switch to release 2.2 of SoundBlaster Pro CD-ROM driver. Include better support for multiple Matsushita controllers. Include media_change changes.
• Check for real tty in set_termios and open line discipline calls.
• If the serial driver couldn't get a transmit buffer from the kernel, it returned the positive error number instead of the correct negative error.
• No need to busy the tty if we're delaying the close.
• Existance test for serial ports improved.
• Now can add serial ports at run-time, to support PCMCIA modems.
• Make sure that line discipline changes are run past set_ldisc().
• Make sure ptys have the usage count on the other tty set correctly.
• Make sure the shared memory stuff is known by the general VM manager.
