Changes from 1.1.24 to 1.1.25

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 patch25.gz

• Put bootable kernel into /boot instead of /.
• Added support for Sound FX as host for Sony CD-ROM.
• Apparently, there is a bug in the floppy FIFO that requires you to force the FIFO to accept a byte even though it insists it isn't ready.
• Even though the dates are old, these changes are apparently new to 1.1.25: October 1993 Bernd Huebner and Ruediger Helsch, Unifix Software GmbH, Braunschweig, Germany: Total rework to speed up data read operation. Also enabled definition of irq and address from bootstrap, using the environment. linux/init/main.c must be patched to export the env. November 93 added code for FX001 S,D (single & double speed). February 94 added code for broken M 5/6 series of 16-bit single speed.
• ramdisk load code moved into its own subroutine, so that we can gram(sic) the floppy IRQ/DMA.
• 3c505 driver changes: renamed to elplus, hard reset needed on a warm reset from DOS after running some drivers, autodetect/autoirq added
• HP LANcard+ drivers added to autoprobe list.
• ac32000 driver renamed to ac3200.
• Added Schneider & Koch G16 Ethernet driver.
• SLIP and CSLIP fixes for memory leaks.
• znote.c renamed to znet.c
• SCSI change notes from Eric Youngdale
  • sd.c, sr.c: Use new check_media_change and revalidate file_operations fields.
  • st.c, st.h: Add changes from Kai Makisara, dated Jun 22.
  • hosts.h: Change SG_ALL back to 0xff. Apparently soft error in /dev/brain resulted in having this bumped up. Change first parameter in bios_param function to be Disk * instead of index into rscsi_disks.
  • sd_ioctl.c: Pass pointer to rscsi_disks element instead of index to array.
  • sd.h: Add struct name "scsi_disk" to typedef for Scsi_Disk.
  • scsi.c: Remove redundant Maxtor XT8760S from blacklist. In scsi_reset, add printk when DEBUG defined.
  • All low level drivers: Modify definitions of bios_param in appropriate way.
• When flushing filesystem buffers, reset b_req also.
• Finish adding media_change calls.
• Allow locking on non-regular files.
• If they were trying to unlock, and it worked, don't return an error.
• An NFS xid mismatch no longer causes the request to be trashed.
• When a socket dies, set the dead flag.
• When returning an ICMP error, return the IP address corresponding to the interface.
• Respond to broadcast ICMP_ECHO (ping) requests.
