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...
if requested. LKMs which need it should use:
SRCS+= vnode_if.h
CLEANFILES+= vnode_if.h vnode_if.c
These rules were already present for VFS LKMs; now they are enabled all
the time. (VFS LKMs do not need the fragment above; it is still done for them.)
- Make a number of filesystems work again when they are statically compiled
(blush)
- FIFOs are no longer optional; ``options FIFO'' removed from distributed
config files.
This code is mostly taken from the 1.1 port (which was in turn taken from
Dave Mills's kern.tar.Z example). A few significant differences:
1) ntp_gettime() is now a MIB variable rather than a system call. A few
fiddles are done in libc to make it behave the same.
2) mono_time does not participate in the PLL adjustments.
3) A new interface has been defined (in <machine/clock.h>) for doing
possibly machine-dependent things around the time of the clock update.
This is used in Pentium kernels to disable interrupts, set `time', and
reset the CPU cycle counter as quickly as possible to avoid jitter in
microtime(). Measurements show an apparent resolution of a bit more than
8.14usec, which is reasonable given system-call overhead.
has no effect now, and MROUTING should never be defined by default.
(Eventually the code should be dynamically loadable.)
Also, allow for Pentium CPUs in GENERICBT kernels.
Add an `install' rule to Makefile.i386, which looks like this:
mv /kernel /kernel.old
install -c -m 555 -o root -g root -fschg kernel /
I'd like comments on whether or not you think it's a good idea to have
the kernel be immutable by default; I'm happy either way.
