Fixed long standing bug in freeing swap space during object collapses.
Fixed 'out of space' messages from printing out too often.
Modified to use new kmem_malloc() calling convention.
Implemented an additional stat in the swap pager struct to count the
amount of space allocated to that pager. This may be removed at some
point in the future.
Minimized unnecessary wakeups.
vm_fault.c:
Don't try to collect fault stats on 'swapped' processes - there aren't
any upages to store the stats in.
Changed read-ahead policy (again!).
vm_glue.c:
Be sure to gain a reference to the process's map before swapping.
Be sure to lose it when done.
kern_malloc.c:
Added the ability to specify if allocations are at interrupt time or
are 'safe'; this affects what types of pages can be allocated.
vm_map.c:
Fixed a variety of map lock problems; there's still a lurking bug that
will eventually bite.
vm_object.c:
Explicitly initialize the object fields rather than bzeroing the struct.
Eliminated the 'rcollapse' code and folded it's functionality into the
"real" collapse routine.
Moved an object_unlock() so that the backing_object is protected in
the qcollapse routine.
Make sure nobody fools with the backing_object when we're destroying it.
Added some diagnostic code which can be called from the debugger that
looks through all the internal objects and makes certain that they
all belong to someone.
vm_page.c:
Fixed a rather serious logic bug that would result in random system
crashes. Changed pagedaemon wakeup policy (again!).
vm_pageout.c:
Removed unnecessary page rotations on the inactive queue.
Changed the number of pages to explicitly free to just free_reserved
level.

argument is now more than just a single flag. (kern_malloc.c)
Used new M_KERNEL value for socket allocations that previous were
"M_NOWAIT". Note that this will change when we clean up the M_ namespace
mess.

some comparisons as it is more correct (we want the kernel page tables
included).
Reorganized some of the expressions for efficiency.
Fixed the new pmap_prefault() routine - it would sometimes pick up the
wrong page if the page in the shadow was present but the page in object
was paged out. The routine remains unused and commented out, however.
Explicitly free zero reference count page tables (rather than waiting
for the pagedaemon to do it).

*so many problems*.. Too bad the snaps themselves don't get made as a
consequence.. :-)
Bump the date forward Yet Another Day. David has some changes he wants to
see rolled in, so I guess we're down for Feb 2nd as the snap date!
correctly (specified wrong fields to awk). Note that the files in question
are noe the local /etc/master.passwd and /etc/passwd files: this Makefile
expects there to be a seperate master.passwd file under /var/yp for NIS
database creation.

Most PCI specific files moved from sys/i386/pci to sys/pci.
One PC specific file (pcibus.c) new in sys/i386/isa.

of hard links: since passwd is installed immutable, an attempt to make
a hard link to it during a 'make install' would fail. I didn't notice
this conflict because my /usr directory is an NFS filesystem mounted from a
SunOS server, so the special file mode flags had no effecti when I tested
everything on my machine. Live and learn.
one line long.
Fixed a bug in the input field with cursor positioning at the end of
the field.
Make the print_status function available to apps so they can print
status messages.
Updated the example for the new fib parser.
