/usr/src/usr.sbin.config:
o -DSTATCLOCK gives kludges to support the rtc non-device as well as
old kludges to support the clk non-device.
/usr/src/usr.sbin/config.8:
o Document the trivialness of the new vector.h.
/usr/src/usr.sbin/mkglue.c:
o Only print DEVICE_NAMES and NR_DEVICES in vector.h. These are
only required to support vmstat. The vmstat interface will need
to be improved for dynamic loading.
/usr/src/usr.sbin/mkioconf.c:
o Print device ids to be used as indexes into DEVICE_NAMES.
o Print secondary interrupt handler entry points (xxxintr()) instead
of primary ones (VdevU()). Primary ones are now XintrI() and
XfastintrI() and are independent of the config so they are not
handled here.
o Minor cleanups.

/usr/src/sys/i386/isa/clock.c:
o Garrett's statclock changes.
o Wire xxxintr, not Vclk.
o Wire using register_intr(), not setidt().
/usr/src/sys/i386/isa/icu.s:
o Garrett's statclock changes.
o Removed unused variable high_imask.
o Fake int 8 for rtc as well as int 0 for clk. Required for kernel
profiling with statclock, harmless otherwise.
/usr/src/sys/i386/isa/isa.c:
o Allow isdp->id_irq and other things in *isdp to be changed by
probes. Changing interrupts later requires direct calls to
register_intr() and unregister_intr() and more care.
ALLOW_CONFLICT_* is brought over from 1.1.5, except
ALLOW_CONFLICT_IRQ is not supported. IRQ conflict checking is
delayed until after probing so that drivers can change the IRQ
to a free one; real conflicts require more cooperation between
drivers to handle.
o Too many details to list.
o This file requires splitting and a lot more work.
/usr/src/sys/i386/isa/isa_device.h:
o Declare more things more completely.
/usr/src/sys/i386/isa/sio.c:
o Prepare to register interrupt handlers as fast.
/usr/src/sys/i386/isa/vector.s:
o Generate entry code for 16 fast interrupt handlers and 16 normal
interrupt handlers. Changed some constants to variables:
# $unit is now intr_unit[intr]. Type is int. Someday it should
be a cookie suitable for the handler (e.g., a struct com_s for
sio).
# $handler is now intr_handler[intr].
# intrcnt_actv[id_num] is now *intr_countp[intr]. The indirection
is required to get a contiguous range of counters for vmstat
and so that the drivers depend more in the driver than on the
interrupt number (drivers could take turns using an interrupt
and the counts would remain correct). There is a separate
counter for each device and for each stray interrupt. In
1.1.5, stray interrupt 7 clobbers the count for device 7 or
something worse if there is no device 7 :-(.
# mask is now intr_mask[intr] (was already indirect).
o Entry points are now _XintrI and _XfastintrI (I = intr = 0-15),
not _VdevU (U = unit).
o Removed BUILD_VECTORS stuff. There's a trace of it left for
the string table for vmstat but config now generates the
string in one piece because nothing more is required.
o Removed old handling of stray interrupts and older comments
about it.

done. This patch was extended to also include a suggested change by
Kirk McKusick which allows the control tty to be reasigned to a different
tty without losing a vnode.
Fixed security problem with telnetd, which allowed
telnet -l -hcert.org localhost
to change the user's host in utmp.
Thanks to Matthew Green <mrgreen@@mame.mu.oz.au> for showing me this one.

not provide the full accuracy of a randomized statistical clock, it does
provide greater accuracy than the previous method, while not significantly
increasing overhead. It also provides profiling support at 1024 Hz.
You must re-compile config before making a new kernel, or you will end
up with unresolved symbols.
Reviewed uy: Bruce evans said it worked for him.
Delete the ifdef GPL_EMULATE case here and made the padding work for
both types of emulators so that there is no longer a need to compile
ps and friends new if you are using the GPL math emulator instead the
normal one.
Added code to check for an adaptec 1542B Version 3.20 Board. This was the
first board that supports >1Gb drives and has the extended bios. So we
need also to disable the exbios like it is done for the 1542C/CF boards.
distributed in keith bostic's nvi (got his permission first). Most changes
are cosmetic, but a few errors (mostly in tty..c) were cleared up.

long long. Done by plugging both eax and edx with -1. This will clobber
edx unnecessarily when the return value is only 32bit...though probably
always an okay thing to do, it could stand a better fix.
This was the cause of gawk being broken (boy was THAT ever a subtle
bug!!!).
