35c10d2239 Got rid of map.h. It's a leftover from the rmap code, and we use rlists.

3fb3086e98 db_disasm.c: Unused var zapped.
pmap.c: tons of unused vars zapped, various other warnings silenced.
trap.c: unused vars zapped.
vm_machdep.c:  A wrong argument, which by chance did the right thing, was
corrected.

2f7048bff0 Make inflate() reentrant - no more global variables.
(The gzip image activator now needs a good code tidy up.)

ee38c19853 First stage of getting imgact_gzip reentrant:
1) cut this up into /sys/sys/inflate.h, sys/kern/inflate.c
sys/kern/ingact_gzip.c
2) make a lot more things static
3) make a lot of globals const
4) make some args const
5) first stage of making globals into a struct (not used yet)

The vm_allocate() call which was introduced between revisions 1.4 and
1.5 of imagact_gzip.c broke things.  I have backed that out for the time
being.  (Davidg: help please)

WARNING: if you have gzip enabled in your kernel, you must now run
config again, as another source file has been added.  Otherwise your
kernel compile will fall over.

This is all still WIP.  More commits to come.

Suggestions from: phk.

c3a82ca0a6 Steven Wallace provided a program which broke this stuff. I guess there are
more weird kinds of a.out than anyone can argue for.  This code failed to
load the first 28K of the text-segment, in the case where the first page
of the a.out contains only the a.out-header, and the text is still at 0x0.
Thanks Steven !

009bc0f68d David Greenman told me to do this: (Thanks!) use vm_allocate to allocate
the uncompression buffer.  Now malloc(M_GZIP) is used for all the Huffman-
tree stuff only.  Numbers so far indicate < 15Kb Malloc use + 32 Kb for
the abovementioned buffer while uncompressing.

0c99df0d8d Added M_GZIP for the imgact_gzip code. The gzip-code is likely to be used

4efda9261d Based on the applause (in this case: not downright rejection :-) I have
cleaned up much of the cruft in this thing.

No printf's in the case where things go well.

Gzip-headers can contain filenames and comments (as long as they're
shorter than the page-size.)

I don't think we leak memory, in the "exec/aout" code.  I'm not quite sure
about the inflate code yet, but I don't think memory is lost.

Q:  Can I add a class M_GZIP to <sys/malloc.h> and bump M_LAST one up
without any thing else needing tweaking ?

37c32e9f3a ***
WARNING:  THIS MATERIAL MIGHT GO AWAY!
This material needs the core-groups approval to stay here for the 2.0 release.
If the core-group does not concent to this commit, it will be backed out.
***

It is a non-gpl'ed "unzip" which will allow execution of a.out files which
have been sent through "gzip -9".  The idea being saved disk-space.

Just now this code has quality rating:  "working prototype".

To compress a file to be used with this, do it exactly this way:

gzip -9 -v < /bin/FOO > /tmp/FOO
remember to chmod /tmp/FOO as needed.

DON'T compress all of you binaries right away !  There are several things
which you should consider first:

1. Using compressed binaries, you use >MUCH< more VM, and thus swap-space.

2. It is slow.

3. It might crash your machine.

Apart from that, I welcome comments...

NB:  There is also a change to sys/conf/files, but cvs core-dumped on me,
so it didn't get into the logs or emailed, but the commit seems to have
happended OK.

bb56ec4a05 While in the real world, I had a bad case of being swapped out for a lot of
cycles.  While waiting there I added a lot of the extra ()'s I have, (I have
never used LISP to any extent).  So I compiled the kernel with -Wall and
shut up a lot of "suggest you add ()'s", removed a bunch of unused var's
and added a couple of declarations here and there.  Having a lap-top is
highly recommended.  My kernel still runs, yell at me if you kernel breaks.
