Updated kernel-contributors list.
Big changes in floppy controller (too many for me to understand).
IDE driver changes for non-disk devices.
Ramdisk driver can now ask the user for the ramdisk.
Console driver now uses memory at 0xa0000 for black&white maps.
lp driver now modularized.
Change to line discipline -- if EOF char, set TTY_PUSH in flags (gets
	rid of gobble_eof).
tty driver now checks for read permission on ioctls.
PLIP driver uses defines instead of literals.
If the filesystem had to write a buffer, search all the lists again.
If the filename being executed is invalid, be sure to return an error.
Buffering added to ext2 fs.
Locking was checking for write permission on its arguments, not read.
NFS changes:
	Do not copy data too often around in the kernel.
	In nfs_file_read the return value of kmalloc wasn't checked.
	Put in a better version of read look-ahead buffering. Original idea
	and implementation by Wai S Kok [email-masked].
	incorrect XID used to confuse Linux.
	use the correct max size, if reading a packet and
	also verify, if the whole packet has been read...
	more checks should be done in proc.c...
Superblock handler now uses a bitmap for tracking devices.
Improvements to sysv/coherent filesystem (now looks for sysv4).
Permit PCI BIOSes with two Service Directories.
System call for interval timers didn't check for read permission on
its memory.
Add a capability to limit a process's cpu time.
time code in kernel wasn't setting the microseconds field to zero everywhere.
Kernel wasn't checking for read permission in stime or settimeofday syscalls.
Skip past '*' character in kernel's vsprintf code.
Read-only virtual memory wasn't implemented quite right.
Some icmp packets were not being put on right device's transmit queue.
Update the loopback route only if there was already one.
