The 40-bit DMA workaround recently implemented for 5714, 5715, and
5780 needs to be expanded because there may be other tg3 devices
behind the EPB Express to PCIX bridge in the 5780 class device.

For example, some 4-port card or mother board designs have 5704 behind
the 5714.

All devices behind the EPB require the 40-bit DMA workaround.

Thanks to Chris Elmquist again for reporting the problem and testing
the patch.

If the AX.25 dialect chosen by the sysadmin is set to DAMA master / 3
(or DAMA slave / 2, if CONFIG_AX25_DAMA_SLAVE=n) ax25_kick() will fall
through the switch statement without calling ax25_send_iframe() or any
other function that would eventually free skbn thus leaking the packet.

Fix by restricting the sysctl inferface to allow only actually supported
AX.25 dialects.

The system administration mistake needed for this to happen is rather
unlikely, so this is an uncritical hole.

VIDEO_CX88_ALSA should not be between VIDEO_CX88_DVB and
VIDEO_CX88_DVB_ALL_FRONTENDS

When cx88-alsa was added to cx88/Kconfig, it was added in between
VIDEO_CX88_DVB and VIDEO_CX88_DVB_ALL_FRONTENDS.  This caused
undesireable effects to the appearance of the menu options in
menuconfig.

This fix reorders cx88-alsa and cx88-dvb in Kconfig, to match saa7134,
and restore the correct menuconfig appearance.

From Dave Johnson <djohnson+linuxmips@sw.starentnetworks.com>:
    
sb1250_gettimeoffset() simply reads the current cpu 0 timer remaining
value, however once this counter reaches 0 and the interrupt is raised,
it immediately resets and begins to count down again.
    
If sb1250_gettimeoffset() is called on cpu 1 via do_gettimeofday() after
the timer has reset but prior to cpu 0 processing the interrupt and
taking write_seqlock() in timer_interrupt() it will return a full value
(or close to it) causing time to jump backwards 1ms. Once cpu 0 handles
the interrupt and timer_interrupt() gets far enough along it will jump
forward 1ms.
    
Fix this problem by implementing mips_hpt_*() on sb1250 using a spare
timer unrelated to the existing periodic interrupt timers. It runs at
1Mhz with a full 23bit counter.  This eliminated the custom
do_gettimeoffset() for sb1250 and allowed use of the generic
fixed_rate_gettimeoffset() using mips_hpt_*() and timerhi/timerlo.

* do_timer() expects the arch-specific handler to take the lock as it

  fixed_rate_gettimeoffset() which reads timerhi/lo.

If a call to set_io_port_base() was being followed by usage of
mips_io_port_base in the same function gcc was possibly using the old
value due to some clever abuse of const.  Adding a barrier will keep
the optimization and result in correct code with latest gcc.

This patch fixes a problem in the ieee80211 probe response and beacon
reception code that would use the packet statistics for a network even
if they were received on a channel other than that which the network
exists on.

This causes a problem in overlapping channels where, for example, a
strong AP on channel 2 could have its beacons received on channels 1 and
3, but at much lower signal levels.  If scanning was done sequentially,
this means the beacon received on channel 3 would update the AP's signal
level as being much lower than it really is, which subsequently could
cause that AP to be passed over and an alternate AP selected.

This patch modifies the driver to support the ipw2200-fw-3.0 image format.

The 3.0 fw image does not add any new capabilities, but as a result of
image format changes, it should fix two problems experienced by users:

1) Race conditions with the request_firmware interface and udev/hotplug
are improved as only a single request_firmware call is now required to
load the firmware and microcode (vs. 3 separate calls previously)

2) The monitor mode firmware (sniffer) is now packaged with the correct
boot image so it can now function without frequent restarts.

Note: Once you apply this patch, you will also need to upgrade your
firmware image to the 3.0 version available from:

Set a meaningful silence threshold value (replacing our previous "0"
default), which gets rid of the gratuitous "Link deterioration"
notifications that we've been receiving from firmware.  This
notification feature tells the driver information to help it determine
when to pre-emptively restart the firmware/ucode in anticipation of
firmware errors!  But since setting this new threshold, I haven't seen
any such notifications.  At least it keeps the logs a little less busy.
