57d3a6d525 add support for terry lambert's loadable kernel modules. 
needs a bit of cleanup, but overall: SLICK!

24fe3e4563 fixed bug where extra spaces at the end of a shell name would 
cause shell scripts to be executed incorrectly.  shells would
receive an *empty* arg for name of script, open it, the kernel
would say "oh, that's ." or something similar, and the results
would be interesting...  found, diagnosed, and killed by me.

b671aede02 slight functionality change to make the rbpack() and 
rbunpack() code that I wrote before work cleaner. Many old drivers
call nnn = q_to_b(queue, buf, len), where nnn gets set to len.
for those who are porting:
	q_to_b(queue, buf, len) --> rbunpack(queue, buf, len)
	b_to_q(buf, queue, len) --> rbpack(buf, queue, len)
ie. they are essentialy drop in replacements now.

a128c34f9c From: Guido van Rooij <guido@gvr.win.tue.nl> 
when mmapping a file, permissions are checked as it should be. When
mprotect()-ing the address range afterwards, no protection was checked
regarding the protection of the file originally opened. So
when you open /usr/bin/su RDONLY and SHARED you could afterwards change
the mmapped region to READ|WRITE. This gave the possibility to obtain
root privs obviously.

b02974b037 Jay Fenlason <hack@datacube.com>: 
1: the fi_readers and fi_writers fields of the fifoinfo structure were not
being initialized to 0.  This caused the driver to not sleep the first
process to open the fifo--it thought there was already another process to
talk to (most of the time.)

2: fifo_open() was calling tsleep() without unlocking the inode of the fifo
file.  This caused *any* subsequent access to the file (even an ls (!)) to
hang forever.  Note that this bug was usually masked by bug #1 above.
