077e6558ec Re-wrote psm_poll_status() to use the ioport supplied in the kernel
config file instead of hard-coding it in the driver.  No functional
differences.

This is based on the code Richard Wiwatowski <rjwiwat@adelaide.on.net>
sent to the mailing list.

9f9b3dc4ae Add three new route flags to help determine what sort of address
the destination represents.  For IP:

- Iff it is a host route, RTF_LOCAL and RTF_BROADCAST indicate local
  (belongs to this host) and broadcast addresses, respectively.

- For all routes, RTF_MULTICAST is set if the destination is multicast.

The RTF_BROADCAST flag is used by ip_output() to eliminate a call to
in_broadcast() in a common case; this gives about 1% in our packet-generation
experiments.  All three flags might be used (although they aren't now)
to determine whether a packet can be forwarded; a given host route can
represent a forwardable address if:

	(rt->rt_flags & (RTF_HOST | RTF_LOCAL | RTF_BROADCAST | RTF_MULTICAST))
	== RTF_HOST

Obviously, one still has to do all the work if a host route is not present,
but this code allows one to cache the results of such a lookup if rtalloc1()
is called without masking RTF_PRCLONING.

3461d589f2 Change the logic of the interrupt/poll loop. It no longer loops until
it empties all of the 256 byte incoming fifo, as it can spend more time
processing one port than intended, especially if data is streaming in
at 115.2K.  The port fifo will be emptied and dumped into the tty system
and left until next time.  I've been running this for quite some time on
one of my systems here.
Also, if the tty layer is blocked or full it lets the hardware assert the
flow control rather than loosing the data.

88d1b64235 Fix a nasty bug that causes random crashes and lockups particularly on
very busy servers (eg: news, web).  This is an interaction between
embryonic processes that have not yet finished forking, and happen to
cause the kernel VM space to grow, hitting the uninitialised variable.

It was possible for this to strike at any time, depending on the size of
your kernel and load patterns.  One machine had paniced occasionally
when cron launches a job since before the 2.1 release.

If you had "options DIAGNOSTIC", you may have seen references to bogus
addresses like 0xdeadc142 and the like.

This is a minimal change to fix the problem, it will probably be done
better by reordering p_vmspace to be in the startzero section, but it
becomes harder to validate then.

It's been vulnerable since pmap.c rev 1.40 (Jan 9, 1995), so it's been a
cause of problems since well before 2.0.5.  This was when the merged
VM/buffer cache and the dynamic growing kernel VM space were first
committed.  This probably fixes a few of PR's.

2dafbfcbab Added calibration the i8254 and the i586 clocks agains the RTC at boot
time.  The results are currently ignored unless certain temporary options
are used.

Added sysctls to support reading and writing the clock frequency variables
(not the frequencies themselves).  Writing is supposed to atomically
adjust all related variables.

machdep.c:
Fixed spelling of a function name in a comment so that I can log this
message which should have been with the previous commit.

Initialize `cpu_class' earlier so that it can be used in startrtclock()
instead of in calibrate_cyclecounter() (which no longer exists).

Removed range checking of `cpu'.  It is always initialized to CPU_XXX
so it is less likely to be out of bounds than most variables.

clock.h:
Removed I586_CYCLECTR().  Use rdtsc() instead.

clock.c:
TIMER_FREQ is now a variable timer_freq that defaults to the old value of
TIMER_FREQ.  #define'ing TIMER_FREQ should still work and may be the best
way of setting the frequency.

Calibration involves counting cycles while watching the RTC for one second.
This gives values correct to within (a few ppm) + (the innaccuracy of the
RTC) on my systems.

a515c85818 Fix the abort code in the BUS DEVICE RESET case. Needed to set cmdlen to 0.
Ensure that queued commands are not touched by the abort code by setting
the SCB status to indicate what queue it is in.

Fix deadlocks when using SCB paging by using SCBs from the assigned_scbs
queue or an SCB that completed during the same interrupt if needed.

Don't ever use insl to pull SCBs from any of the controllers.  You can
only do 8bit PIO reads.  This only affected SCB paging.

With this checkin, SCB paging works quite a bit better, but I still have
some problems with it that may be caused by a firmware problem in my
PD1800s.  It seems that using a tag number higher than the maximum number
of tags allowed by the device, confuses it.  For example, if I queue
two commands, tagged 3 and 36, it never reconnects for tag 36.

SCB paging is enabled with the option "AHC_SCBPAGING_ENABLE".  Full

options "AHC_TAGENABLE" and "AHC_QUEUE_FULL" have been removed.  The

9c9137ea6c Three speed-ups in the output path (two small, one substantial):
1) Require all callers to pass a valid route pointer to ip_output()
   so that we don't have to check and allocate one off the stack
   as was done before.  This eliminates one test and some stack
    bloat from the common (UDP and TCP) case.

2) Perform the IP header checksum in-line if it's of the usual length.
    This results in about a 5% speed-up in my packet-generation test.

3) Use ip_vhl field rather than ip_v and ip_hl bitfields.

01a95d942e Don't use a newfangled auto initializer. Initialize everything by
assignment to avoid one bug and several pessimizations.

In the old version, gcc-2.6.3 (i386 version) generates 16 bytes
of static data and copies it using 4 4-byte load-stores.  gcc-2.7.2
generates 2 1-byte stores and calls memset() to zero 14 bytes.
Linking fails because memset() doesn't exist in the kernel.

In both versions, the 2 bytes stored directly are all that is
actually used unless the null padding at the end is used, since
the 3 4-byte words in the middle are initialized again by struct
assignment.  These words are misaligned.  gcc generates misaligned
load-stores for (small) misaligned struct copies.
