kernel BUG at drivers/net/phy/mdio_bus.c:165!
Unable to handle kernel NULL pointer dereference at virtual address 00000000
How?
mdiobus_alloc() sets bus->state = MDIOBUS_ALLOCATED.
mdiobus_register() sets bus->state = MDIOBUS_REGISTERED but then can
fail (mdiobus_scan()) returning an error to the caller.
The caller aborts correctly with mdiobus_free() which does:
if (bus->state == MDIOBUS_ALLOCATED) {
kfree(bus);
return;
}

A bug in the fusion driver was exposed by the switch to block timeout.
Basically, drivers are supposed to terminate commands once error
handling begins on them. The fusion apparently wasn't doing this.
Under the old timeout regime, completions on terminated commands would
by and large get ignored because of the way command timeouts used to
work. The new block timers are very intolerant to this, though,
becuase the request gets cleaned and freed.

When the tuner modules were moved to common/tuners, a separate customize
option were added for tuners. However, the automatic selection of the
tuners were still using the older option.
This causes that the automatic selection to fail, if DVB_FE_CUSTOMISE is
selected. Also, since those tuners are now under MEDIA_TUNER_CUSTOMIZE
menu, if you unset MEDIA_TUNER_CUSTOMIZE, you can't manually select the
tuners.
This patch fixes this error by replacing DVB_FE_CUSTOMISE by
MEDIA_TUNER_CUSTOMIZE on all places were a tuner is selected.
The patch were generated by this small script:
for i in `find drivers/media -name Kconfig`; do
cat $i|perl -ne 's/(MEDIA_TUNER.*)DVB_FE_CUSTOMISE/\1MEDIA_TUNER_CUSTOMIZE/; print $_' >a
mv a $i

At some point the Flexcop driver was changed to support newer Flexcop cards.
These modifications however broke the detection of Cablestar 2 DVB-C cards.
The reason is that the earlier version of the driver used to retry
unsuccessful i2c operations. The demodulator of Cablestar 2 cards (stv0297)
seems to be very dependent on these retries and adding them back fixes
Cablestar detection.
This patch restores this behaviour for the CableStar2.

For the console, there is a 1:1 mapping of glyphs which cannot be found
in the current font. This seems to be meant as a kind of 'emergency
fallback' for fonts without unicode mapping which otherwise would
display nothing readable on the screen.
At the moment it affects all chars for which no substitution character
is defined. In particular this means that for all chars (>= 128) where
there is no iso88591-1/unicode character (e.g. control character area)
you'll get the very strange 1:1 mapping of the (cp437) graphics card
glyphs.
I'm pretty sure that the 1:1 mapping should only affect strict ASCII
code characters, i.e. chars < 128.
The patch limits the mapping as it probably was meant anyway.

The pktcdvd created class devices only export some sysfs files,
but have no char dev_t registered in the driver.
At class device creation time they copy the dev_t value of the
block device to the char device, wich will register a new char
device in the driver core and userspace, with a conflicting dev_t
value.
In many cases the class devices dev_t just points to a random

Add a call to cancel_work_sync() in fbcon_exit() to cancel any pending
work in the fbcon workqueue.
The current implementation of fbcon_exit() sets the fbcon workqueue
function info->queue.func to NULL, but does not assure that there is no
work pending when it does so. On occasion, depending on system timing,
there will still be pending work in the queue when fbcon_exit() is
called. This results in a null pointer deference when run_workqueue()
tries to call the queue's work function.

The firewire nodemanager function "nodemgr_host_thread" contains a loop
that calls try_to_freeze near the top of the loop, but then delays for
up to 3.25 seconds (plus time to do work) before getting back to the top
of the loop. When starting a cycle post-boot, this doesn't seem to bite,
but it is causing a noticeable delay at boot time, when freezing
processes prior to starting to read the image.
The following patch adds invocation of try_to_freeze to the subloops
that are used in the body of this function. With these additions, the
time to freeze when starting to resume at boot time is virtually zero.
I'm no expert on firewire, and so don't know that we shouldn't check
the return value and jump back to the top of the loop or such like after
being frozen, but I submit it for your consideration.

try_to_freeze() without any jump is correct. The surrounding code in
the respective loops will catch whether another bus reset happens during
the freeze and handle it.

As reported by Hermann Lauer, PCS PHY support in the sungem
driver simply doesn't work.
When the chip is reset due to open, or some other similar operation,
the PCS is reset too but we don't program it back into a running
state. The result is no link when the device is brought up.
This partially rectifies the situation for the moment, by kicking
the PCS after a sungem chip reset so that it will renegotiate and
be re-enabled again.
The behavior is still a little bit dodgy as the added renegotiate
make the link take some time after bringing the interface up,
but this is a significant improvement in that things actually work
now :-)
Based almost entirely upon an initial patch by Hermann.

Some systems report SIS 5513 as both vendor/id and subvendor/id
string. In that case we can't distinguish the system by the id
svid/sdid and in fact the entry here breaks some boxes. At some
point we need to find another way to detect the Targa Visionary 1000,
until then this trades a hang for some users with lower performance
for others.

Since applying the fix suggested by the errata (disabling MSI), we've had
issues with interrupts being stuck on despite IIR being 0 on GM965 hardware.
Most reporters of the issue have confirmed that turning MSI back on fixes
things, and given the difficulties experienced in getting reliable MSI working
on Linux, it's believable that the errata was about software issues and not
actual hardware issues.

Mapping the destination multiple times is a misuse of the dma-api.
Since the destination may be reused as a source, ensure that it is only
mapped once and that it is mapped bidirectionally. This appears to add
ugliness on the unmap side in that it always reads back the destination
address from the descriptor, but gcc can determine that dma_unmap is a
nop and not emit the code that calculates its arguments.

This reverts commit 558073dd56, along with
the failed try to fix the regression it caused ("ACPI: Fix ACPI battery
regression introduced by commit 558073"), which just made things worse.
Commit aaad077638 (that failed "Fix ACPI
battery regression") got the voltage conversion confused, and fixed the
problem with Rafael's battery monitor apparently just by mistake.
So revert them both, getting us back to the 2.6.27 state in this, and
let's revisit it when people understand what's going on.

Under my 2.6.28-rc6 sparc64, when associating to an AP through my
zd1211rw device, I was seeing kernel log messages like (not exact output):
Kernel unaligned access at TPC[10129b68] zd_mac_rx+0x144/0x32c [zd1211rw]
For the zd1211rw module, on RX, the 80211 packet will be located after
the PLCP header in the skb data buffer. The PLCP header being 5 bytes
long, the 80211 header will start unaligned from an aligned skb
buffer.
As per Documentation/unaligned-memory-access.txt, we must replace the
not unaligned() safe compare_ether_addr() with memcmp() to protect
architectures that require alignment.

In "ipw2200: Call netif_*_queue() interfaces properly", netif_stop_queue()
and netif_wake_queue() were removed with the reason
"netif_carrier_{on,off}() handles starting and stopping packet flow into
the driver". The patch also removes a valid condition check that
ipw_tx_skb() cannot be called if device is not in STATUS_ASSOCIATED state.
But netif_carrier_off() doesn't guarantee netdev->hard_start_xmit won't
be called because linkwatch event is handled in a delayed workqueue. This
caused a kernel oops reported by Frank Seidel:
https://bugzilla.novell.com/show_bug.cgi?id=397390
This patch fixes the problem by moving the STATUS_ASSOCIATED check back
to ipw_tx_skb(). It also adds a missing netif_carrier_off() call to
ipw_disassociate().

This patch cleans uCode key table bit map iwl_clear_stations_table
since all stations are cleared also the key table must be.
Since the keys are not removed properly on suspend by mac80211
this may result in exhausting key table on resume leading
to memory corruption during removal
This patch also fixes a memory corruption problem reported in
http://marc.info/?l=linux-wireless&m=122641417231586&w=2 and tracked in
http://bugzilla.kernel.org/show_bug.cgi?id=12040.
When the key is removed a second time the offset is set to 255 - this
index is not valid for the ucode_key_table and corrupts the eeprom pointer
(which is 255 bits from ucode_key_table).

Now that the CPU and GTT domain operations are isolated to their own
