previous snap. Specifically, kern_exit and kern_exec now makes a
call into the pmap module to do a very fast removal of pages from the
address space. Additionally, the pmap module now updates the PG_MAPPED
and PG_WRITABLE flags. This is an optional optimization, but helpful
on the X86.
- fixed a sloppy common-style declaration.
- removed an unused macro.
- moved once-used macros to the one file where they are used.
- removed unused forward struct declarations.
- removed __pure.
- declared inline functions as inline in their prototype as well
as in theire definition (gcc unfortunately allows the prototype
to be inconsistent).
- staticized.
This fixes the kernel panic when propagating userconfig changes to
arbitrary kernels.
Remove obsoleted `#include <tcl.h>' added a few <stdio.h> where
necessary.
Fix getting scsi bus information from an -incore kernel.
Turned on SAVE_USERCONFIG by default.
<net/if_arp.h> and fixed the things that depended on it. The nested
include just allowed unportable programs to compile and made my
simple #include checking program report that networking code doesn't
need to include <sys/socket.h>.
required. a core is not dumped at first connecting time and
dumped at second or third time. (patch I)
2. A routine for "show route" refers out of allocated space.
Values pointed by "lp" should be read as CHAR, I think.
there is also no free() for disallocation. (patch II)
Here is also a patch for an improvement: In current imprementation,
even if PPP connection is disconnected by time out, prompt of
interactive mode does not change from "PPP>" to "ppp>" to
indicate the disconnection on a terminal.
So I modified the code to do that. (patch III)

Still no support for Ultra-SCSI and other new features, but the code
should now correctly initialize the clock pre-scaler (based on freqency
measurement results, if necessary).
Fix support of 16 targets for WIDE SCSI.
Disable bus reset in case no progress is made for too long ("ncr dead"
message), which did not work too well with scanners and other slow devices.
(yes I had tested the hell out of this).
I've also temporarily disabled the code so that it behaves as it previously
did (tail drop's the syns) pending discussion with fenner about some socket
state flags that I don't fully understand.

information in a prettier form.
if a single process is performing a large number of requests (in this
case writing a large file). The writing process could monopolise the
recieve lock and prevent any other processes from recieving their
replies.
It also adds a new sysctl variable 'vfs.nfs.dwrite' which controls the
behaviour which originally pointed out the problem. When a process
writes to a file over NFS, it usually arranges for another process
(the 'iod') to perform the request. If no iods are available, then it
turns the write into a 'delayed write' which is later picked up by the
next iod to do a write request for that file. This can cause that
particular iod to do a disproportionate number of requests from a
single process which can harm performance on some NFS servers. The
alternative is to perform the write synchronously in the context of
the original writing process if no iod is avaiable for asynchronous
writing.
The 'delayed write' behaviour is selected when vfs.nfs.dwrite=1 and
the non-delayed behaviour is selected when vfs.nfs.dwrite=0. The
default is vfs.nfs.dwrite=1; if many people tell me that performance
is better if vfs.nfs.dwrite=0 then I will change the default.

null, but warn if there was an error reading it.

no point in adding them again. This doesn't fix any bugs; it's just for
efficiency.
features are used without testing for i586 features that they depend
on. Configuring option PERFMON without configuring a suitable cpu

(1) Merged i386/i386/sb.h, deleted pc98/pc98/sb.h.
(2) pc98/conf/GENERIC8 looks more like i386/conf/GENERIC now.
(3) Fixed display bug in pc98/boot/biosboot/io.c.
(4) Prepare to merge memory allocation routines:
pc98/i386/locore.s
pc98/i386/machdep.c
pc98/pc98/pc98_machdep.c
pc98/pc98/pc98_machdep.h
(5) Support new board "C-NET(98)":
pc98/pc98/if_ed98.h
pc98/pc98/if_ed.c
(6) Make sure FPU is recognized for non-Intel CPUs:
pc98/pc98/npx.c
(7) Do not expect bss to be zero-allocated:
pc98/pc98/pc98.c
