Changes from 1.1.73 to 1.1.74

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 patch74.gz

• Jeff Tranter added to CREDITS.
• Cyclades async mux driver added.
• More SPARC additions.
• SBPro version 2.9 adds support for the Longshine LCS-7260. IOCTL added for multisession support.
• Console switching changed a little, to add a memory of the last console.
• Oops. Unprotected get_fs_long in serial IOCTL handler (set_modem_info call in serial.c). This means that you could access memory that you didn't have read permission for.
• Don't let anyone but the superuser change the keyboard and/or video mode.
• The dummy networking driver doesn't do ARP.
• EtherExpress driver doesn't set the multicast list.
• PLIP driver improved, also registers the I/O ports it uses.
• EATA driver now supports ISA boards (DPT PM2011, DPT PM2021), and uses DMA. EISA boards should be level triggered.
• SCSI block devices can sometimes deadlock. Code was added to unlock them.
• Oops, a few SCSI printk's used the wrong format.
• SCSI tape timeout increased.
• SCSI file mark counter increased only if positive.
• All ISA boards get host->block set so we can support multiple ISA boards reliably.
• CDROM Multisession support added to isofs.
• Make sure we have read permission on the file times structure for all fs's.
• Oops, didn't set the type of the superblock when initializing the structure.
• Search for the SBPro card at 0x340 before the one at 0x230.
• Call the calibrate_delay routine before the character and block device initialization.
• Reset to TIME_WRITE on a WRITE timeout instead of a TIME_CLOSE.
• BSD time wait code was frobbed.
