33MHz for calculating the latency timer values for its children.
Inspired by NetBSD doing the same and Linux as well as OpenSolaris
using a similar approach.
While at it rename a variable and change its type to be more
appropriate fuer values of PCI properties so the variable can be
more easily reused.
- Initialize the cache line size register of PCI devices to a
legal value; the cache line size is limited to 64 bytes by the
Fireplane/Safari, JBus and UPA interconnection busses. Setting
it to an unsupported value caused bad performance at least with
GEM as it causes them to not do cache line bursts and to not
issue cache line commands on the PCI bus.

vlan differences, etc).
- New Darwin, FreeBSD, and NetBSD versions.
- DragonFly support including the new .Dx macro.
- New .St strings: -isoC-amd1, -isoC-tcor1, -isoC-tcor2, and -ieee1275-94.
- In sunkbd_probe_keyboard() don't bother to determine the keyboard layout
as we have no use for that info. Instead let this function return the
keyboard ID and verify at its invocation in sunkbd_configure() that we're
talking to a Sun type 4/5/6 keyboard, i.e. a keyboard supported by this
driver.
- Add an option SUNKBD_EMULATE_ATKBD whose code is based on the respective
code in ukbd(4) and like UKBD_EMULATE_ATSCANCODE causes this driver to
emit AT keyboard/KB_101 compatible scan codes in K_RAW mode as assumed by
kbdmux(4). Unlike UKBD_EMULATE_ATSCANCODE, SUNKBD_EMULATE_ATKBD also
triggers the use of AT keyboard maps and thus allows to use the map files
in share/syscons/keymaps with this driver at the cost of an additional
translation (in ukbd(4) this just is the way of operation).
- Implement an option SUNKBD_DFLT_KEYMAP, which like the equivalent options
of the other keyboard drivers allows to specify the default in-kernel
keyboard map. For obvious reasons this made to only work when also using
SUNKBD_EMULATE_ATKBD.
- Implement sunkbd_check(), sunkbd_check_char() and sunkbd_clear_state(),
which are also required for interoperability with kbdmux(4).
- Implement K_CODE mode and FreeBSD keypad compose.
- As a minor hack define KBD_DFLT_KEYMAP also in the !SUNKBD_EMULATE_ATKBD
case so we can obtain fkey_tab from <dev/kbd/kbdtables.h> rather than
having to duplicate it and #ifdef some more code.
- Don't use the TX-buffer for writing the two command bytes for setting the
keyboard LEDs as this consequently requires a hardware FIFO that is at
least two bytes in depth, which the NMOS-variant of the Zilog SCCs doesn't
have. Thus use an inlined version of uart_putc() to consecutively write
the command bytes (a cleaner approach would be to do this via the soft
interrupt handler but that variant wouldn't work while in ddb(4)). [1]

MFC: Fix man(1) to allow .so to reference a compressed file
Original PR description:
man(1) can't handle compressed included files.
Some ports will install with compressed manpages. man handles
this by looking for the .gz version of a man source file.
It is also common to include other files with the .so
directive where commands or functions share a man page.
Traditionally ports have had to handle this by either not
compressing the manpages, or using the _MLINKS macro in the
port makefile to create symlinks to the actual source file,
rather than using .so versions. Notably, the current version
of Xorg port breaks. See ports/113096 and ports/115845.
Remove the *_queue() variants of various sleepq and turnstile functions

These APIs are internal APIs only used to implement higher level primitives
such as locks and condition variables.
MFC some comment updates to account for multi-queue support missed earlier
as well as a few other changes (whitespace, style, etc.) to reduce diffs
with HEAD.
- Remove some debugging nits in the MFC of rwlocks that looked for cases
where a reader blocked on a lock with no owner and just assert that it
never happens like HEAD.
- Actually set td->td_tsqueue to the sub-queue of a turnstile that a
thread is actually enqueued to. Otherwise, the kernel would always
think that threads were on the queue for exclusive (write) waiters
(queue 0). Thus, if the priority of a thread waiting on a read lock
was adjusted while it was waiting it could result in corrupting the
queue of waiting threads.
A few tweaks to reduce diffs with HEAD including using lock_init() and
lock_destroy() and adding a missing #include so that NO_ADAPTIVE_RWLOCKS
is honored.

Disable the module building of the linux bits on alpha and remove them
from the corresponding NOTES. [1]
There's no corresponding linux_base in the Ports Collection since years,
and no linux distribution which is up-to-date and suitable (security,
widespread, ...) for us. The only complain regarding linux & alpha
we got so far is that the linuxulator doesn't build anymore. This
complaint came from wilko -- the alhpa-part of re@ -- only. As the
alpha platform is dead (no support from the manufacturer / linux
distributions) and deprecated (removed in -current) it was decided to
disable the linux bits from the build instead of trying to fix the
problems on alpha.
The alpha parts in the source are not removed so far, in case there are
1-2 people which actually still make use of this and are interested to
use the linuxulator (and fix the problems). Additionally this prevents
regressions on i386/amd64 when removing the alpha bits in shared code
(the people which care about those code parts don't have enough time ATM
to do extensive testing). This decission may be revisited at a later
point in time.
Add SCSI READ CAPACITY support to camcontrol. The new 'readcap' subcommand

- Use our own callout instead of if_slowtimo() for driving lance_watchdog()

- Use bus_get_dma_tag() to obtain the parent DMA tag so le(4) works on

- Remove BUS_DMA_WAITOK from bus_dma_tag_create() invocations as it's
no valid flag there.
- For setting the port PCnet chips must be powered down or stopped and
unlike documented may not take effect without an initialization. So
don't invoke (*sc_mediachange) directly in lance_mediachange() but
go through lance_init_locked(). It's suboptimal to impose this for
all chips but given that besides the affected PCI bus front-end the
only other front-end which supports media selection is and likely
ever will be the 'ledma' front-end I see not enough reason to break
the in-driver API for this (though one could argue both ways here).

o Revised MII support:
- In hme_stop() mask all interrupts.
- In hme_eint() print MIF register contents on MIF interrupts.
- In hme_mifinit() don't bother to preserve the previous MIF config.
This was mainly done in order to preserve the PHY select bit (external
or internal PHY) but which only needs to be set as appropriate when
reading from or writing to the desired PHY in hme_mii_{read,write}reg().
Similarly don't bother to set the PHY select bit in hme_mii_statchg().
- In hme_mii_{read,write}reg() ignore requests to PHYs other than the
external and internal PHY one.
- Move enabling/disabling the MII drivers of the external transceiver from
hme_init_locked() and based on the sheer presence of an external one
to hme_mifinit() and based on the currently selected media, defaulting
to the internal transceiver when the media hasn't been set, yet.
Invoke hme_mifinit() from the newly added hme_mediachange_locked() so
the setting of the MII drivers is updated when changing media.
These changes keep the MII bus from wedging (which manifests in the HME
and the PHYs no longer being able to communicate with each other) when
the PHY device drivers isolate the unused PHY in two-PHY configurations
as present in f.e. Netra t1 100 while changing media, either from
hme_init_locked() (see also below) or via ifconfig(8) (not with the
RELENG_6 ifconfig(8) and miibus(4) though). They also allow for using
both transceivers/PHYs.
- In the newly added hme_mediachange_locked() also reset the PHYs in two-
PHY configurations before invoking mii_mediachg(). This is required
for successfully unisolating the previously unused PHY when switching
between PHYs.
- Now that changing media should no longer cause problems back out rev.
1.27 and re-enable setting the current media in hme_init_locked() (see
the commit message of rev. 1.23 for more info).
These changes are roughly a merge of NetBSD hme.c rev. 1.32 - 1.35 (1.30
was already fixed differently in our 1.36; 1.31 and 1.32 were wrong) with
some parts reworked and things that don't make sense like setting the MII

write}reg() omitted.

However, there are many cases that the signal is unusable. Moreover, some
