is only appropriate to use in the special environment of start.S (real
mode plus some conventions about not saving registers), and asm.h is
supposed to be for generic macros.
Removed some unnecessary parentheses.
Finished the constant poisoning that was begun in rev.1.14. Consts
aren't very poisonous (or useful) unless -Wcast-qual is in CFLAGS,
and it isn't in the default CFLAGS.
This stuff should not be too destructive if the IPDIVERT is not compiled in..
be aware that this changes the size of the ip_fw struct
so ipfw needs to be recompiled to use it.. more changes coming to clean this up.
apm_setup.s was storing apm_cs16_base and apm_cs32_base addresses in
each others slots, and apm.c was reversing the result so the bugs
cancelled out, but the code looked wrong.
No functional differences unfortunately.

type identification code out of machdep.c and into a new file of its
own. Hopefully other grot can be moved out of machdep.c as well
(by other people) into more descriptively-named files.
Add code to the boot blocks to allow the user to place default boot strings
on block 1 of the disk (2nd block), should the correct magic numbers be present.
If the correct options are used it will 'delete' the name used from block1,
thereby assuring that if the boot fails it won't be stuck in an infinite loop.
the boot strings are set by the utility "nextboot"
(not yet checked in, but being tested.)
By default these changes should have no effect on existing installations
and if compiled without the NAMEBLOCK option should be essentially identical
to the old ones.
based on the HD64570 chip. Both the 1 and 2 port cards is supported.
Line speeds of up to 2Mbps is possible. At this speed about 95% of the
bandwidth is usable with 486DX processors.
The standard FreeBSD sppp code is used for the link level layer. The
default protocol used is PPP. The Cisco HDLC protocol can be used by
adding "link2" to the ifconfig line in /etc/sysconfig or where ever
ifconfig is run.
At the moment only the X.21 interface is tested. The others may need
tweaks to the clock selection code.
Testing with the high frequency of 20000 Hz (to find problems) only found
the problem that this frequency is too high for slow i386's.
Disable interrupts while setting the timer frequency. This was unnecessary
before rev.1.57 and forgotten in rev.1.57. The critical (i8254) interrupts
are disabled in another way at boot time but not in the sysctl to change
the frequency.
Fixed profiling of system times. It was pre-4.4Lite and didn't support
statclocks. System times were too small by a factor of 8.
Handle deferred profiling ticks the 4.4Lite way: use addupc_task() instead
of addupc(). Call addupc_task() directly instead of using the ADDUPC()
macro.
Removed vestigial support for PROFTIMER.
switch.s:
Removed addupc().
resourcevar.h:
Removed ADDUPC() and declarations of addupc().
cpu.h:
Updated a comment. i386's never were tahoe's, and the deferred profiling
tick became (possibly) multiple ticks in 4.4Lite.
Obtained from: mostly from NetBSD
multiplication in addupc() overflowed for addresses >= 256K, assuming
the usual profil(2) scale parameter of 0x8000. addupc() will go away
soon.

via an ioctl (MOUSE_ACTION).
Fixed a couple of bugs (destructive cursor, uncut, jitter).
Now applications can use the mouse via the MOUSE_MODE ioctl, its
possible to have a signal sent on mouseevents, makeing an event loop
in the application take over mouseevents.
things tend to work better if you write the settings to the correct
register.. (*blush*). This subtle bug has been haunting me for ages, and
will solve a few problems that have been reported to me.
Also, take a shot at fixing the serial BREAK processing, what was there
before never really worked. (There is a PR on this I think)
Real support for a Textmode mousecursor, works by reprogramming the
charset. Together with this support for cut&paste in text mode.
To use it a userland daemon is needed (moused), which provides
the interface to the various mice protokols.
Bug fixes here and there, all known PR's closed by this update.
