the one place that depended on it. wakeup() is now prototyped in
<sys/systm.h> so that it is normally visible.
Added nested include of <sys/queue.h> in <vm/vm_object.h>. The queue
macros are a more fundamental prerequisite for <vm/vm_object.h> than
the wakeup prototype and previously happened to be included by
namespace pollution from <sys/proc.h> or elsewhere.
controllers, it is an error to issue a command before the keyboard
has had time to reply to the previous command. Setting the LEDs
involves issueing 2 commands, so it never worked on these keyboards.
Fixed resetting of keyboard. It is possible for unprocessed
scancodes to be present when the reset routine is called. This
usually occurs after switching from one console driver to another
in userconfig. pcvt and syscons attempt to flush any stale scancodes,
but sometimes fail to do so because keyboard and/or keyboard
controller takes a long time to send the scancodes after reset
(scancodes are apparently not flushed by reset!). syscons handles
this later by not checking for errors at strategic places, but pcvt
was confused.
Use an impossible initial and failure mode setting for the LEDs
so that the LEDs always get set if they are possibly out of sync.
Added missing spltty() in update_led().
shipped with freebsd can be changed without modifying the Makefiles directly.

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.
<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>.
features are used without testing for i586 features that they depend
on. Configuring option PERFMON without configuring a suitable cpu
still doesn't fail right.
(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

I586_OPTIMIZED_BCOPY is configured.
Similarly for bzero/I586_OPTIMIZED_BZERO.
Fake 586's had better have a hardware FPU with non-broken exception
handling (we mask exceptions, but broken exception handling may trap
on the instructions that do the masking). I guess this means that
the routines won't work on most 386's or FPUless 486's even when they
have a h/w FPU.
These are based on using the FPU to do 64-bit stores. They also
use i586-optimized instruction ordering, i586-optimized cache
management and a couple of other tricks. They should work on any
i*86 with a h/w FPU, but are slower on at least i386's and i486's.
They come close to saturating the memory bus on i586's. bzero()
can maintain a 3-3-3-3 burst cycle to 66 MHz non-EDO main memory
on a P133 (but is too slow to keep up with a 2-2-2-2 burst cycle
for EDO - someone with EDO should fix this). bcopy() is several
cycles short of keeping up with a 3-3-3-3 cycle for writing. For
a P133 writing to 66 MHz main memory, it just manages an N-3-3-3,
3-3-3-3 pair of burst cycles, where N is typically 6.
The new routines are not used by default. They are always configured
and can be enabled at runtime using a debugger or an lkm to change
their function pointer, or at compile time using new options (see
another log message).
Removed old, dead i586_bzero() and i686_bzero(). Read-before-write is
usually bad for i586's. It doubles the memory traffic unless the data
is already cached, and data is (or should be) very rarely cached for
large bzero()s (the system should prefer uncached pages for cleaning),
and the amount of data handled by small bzero()s is relatively small
in the kernel.
Improved comments about overlapping copies.
Removed unused #include.
I have only tested the ABP5140 card and only with a single CDROM drive
but it seems to work fine. This driver relies on features found only in
the SCSI branch so will not work in -current until those changes
are brought in. It also doesn't have any error handling code *yet*.
The goal is to use this driver as the development platform for the new
generic SCSI layer error recovery/handling code.
PCI and EISA front ends will show up as soon as I get my hands on
the cards. There are also a few issues in the driver that I need
to clear up with AdvanSys before I can suggest sticking one of
these cards in your server. 8-)

[long long] results when I last worked on them, but they are normally
used together with to daddr_t's and off_t's which are signed, so the
unsigned results did little except cause warnings.
The main change is from unsigned long unsigned int. It just needs to
be a 32-bit type and unsigned int is most natural. Using a non-long
type has the "advantage" of hiding bugs in the "machine-independent"
code where it prints foo_t's using %d or %x. These bugs are currently
hidden bug not compiling with -Wformat.
I tried changing vm_ooffset_t from long long to unsigned long long, but
that was wrong because vm_ooffset_t needs to be long to match off_t,
although file offsets are never negative.
