bb7008423c This commit is as a result of a comment by Alan Cox (alc@cs.rice.edu) 
regarding the "real" problem with maps that we have been having
over the last few weeks.  He noted that the first_free pointer was
left dangling in certain circumstances -- and he was right!!!   This
should fix the map problems that we were having, and also give us the
advantage of being able to simplify maps more aggressively.

APM_GETINFO ioctl.

665e2fe6cf Make sure that we pmap_update AFTER modifying the page table entries. 
The P6 can do a serious job of reordering code, and our stuff could
execute incorrectly.

ba0b5e96d0 Remove references to MAP_FILE.. That is now "default" and is only 
a "#define MAP_FILE 0" that is still there for net-2 source compatability.

a693ae062d The same data segment length rounding problem that was in the elf 
loader is also present in the coff loader.  It was possible to get one
more page allocated than needed, which would cause brk()/malloc()/etc
to fail with ENOMEM when it tried to re-allocate the space.

Also, change a bcopy() from kernel to user space to a copyout().

df05bab7f8 Allow mmap'ed devices to work correctly across forks. The sanest

the parent.

d3d6c3d3ef Do a APM BIOS dis-connect before attempting to do a 32-bit connection 
just in case a connection already existed.

Also, a minor optimization in the code which determins if a APM BIOS exists.

Reviewed by:	phk

This is based on the APM-0.5 patch for Linux, but written entirely by me.

99d2273f94 If FAILSAFE is defined, then: 
- Do not enable tagged commands by default
- Probe only 1 LUN
- Do not negotiate sync. transfer with CDROM drives

Defining FAILSAFE will result in a driver that will tolerate
marginal hardware for the price of a slight loss of performance
It is intended for use in install kernels.

a30b0a83b7 Changed socket code to use 4.4BSD queue macros. This includes removing 
the obsolete soqinsque and soqremque functions as well as collapsing
so_q0len and so_qlen into a single queue length of unaccepted connections.
Now the queue of unaccepted & complete connections is checked directly
for queued sockets. The new code should be functionally equivilent to
the old while being substantially faster - especially in cases where
large numbers of connections are often queued for accept (e.g. http).
