Changes from 1.1.88 to 1.1.89

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 patch89.gz

• Alpha and Sparc changes.
• Power saving mode sometimes causes an NMI on i386.
• Remove int 3 emulation in vm86.
• If you do *not* have an Aztech/Orchid/Okano/Wearnes drive and want to bypass drive detection during Linux boot up, start with boot parameter aztcd=0.
• Volume control for cdrom playback added to Aztech.
• Don't halt while doing DMA to/from the floppy.
• Copy memory out of the console driver using writew instead of a memcpy.
• Add calls to enable_bh (bottom half) as needed.
• Suck out register-printing code from keyboard driver and plop it into a machine-specific file.
• Cheapo timeout isn't long enough for an Alpha, which executes an infinite loop (yeah, you all heard the joke already)...
• Change TIOCLINUX to return the right error code on an invalid call.
• ni5210 driver improved (see source for details).
• PPP driver modularized.
• EATA improvements and modularization (now version 1.14.03).
• Qlogic SCSI PCMCIA improvements.
• HITACHI DK314C CR21 added to SCSI blacklist (responds to all LUN).
• SCSI tape is better at finding file marks.
• UltraStor 14F/34F now has module support.
  • Log and do a retry when a disk drive returns a target status different from zero on a recovered error.
  • Auto detects if U14F boards have an old firmware revision.
  • Max number of scatter/gather lists set to 16 for all boards (most installation run fine using 33 sglists, while other has problems when using more then 16).
• HPFS fs capitalization implemented more cleanly.
• New files in /proc/net to reset counters.
• Aztech CD-ROM IOCTL added to close the tray.
• IPIP tunneling added.
• Appletalk sockets added.
• Semaphore code rewritten (see source for details).
• Time zone adjustment code cleaned up.
• Fix a race condition in kfree().
• Add a policy setting to ip forwarding, for firewalling.

• Allow anyone to clear the SO_DEBUG option on a socket.
• Use a 1MHZ clock for picking sequence numbers.
