Whenever an external device is resetted we really have to take
care to keep the channel in sync. Just notifying SCSI-ML and retry
is not enough as we have to make sure the SCSI bus is not getting
confused, either.
So whenever we detect an external reset we rewrite the command to
TUR, disable packetized command and notify the internal engine
that an abort has happened. This way we trigger a proper bus
reset sequence and all devices will be renegotiated properly.
Kudos to Justin Gibbs and Luben Tuikov for this idea.

The transport class recv mempools are causing slab corruption.
We could hack around netlink's lack of mempool support like dm,
but it is just too ulgy (dm's hack is ugly enough :) when you need
to support broadcast.
This patch removes the recv pools. We have not used them even when
we were allocting 20 MB per session and the system only had 64 MBs.
And we have no pools on the send side and have been ok there. When
Peter's work gets merged we can use that since the network guys
are in favor of that approach and are not going to add mempools
everywhere.

Early ISP2432 parts have a known hardware issue when coming
out of a D3 hot state. This issue can result in a hung PCIe
link. Recent firmwares contain a workaround whereby the
stop-firmware mailbox command prevents the ISP from entering
the D3 hot state.
In order to ensure that the workaround succeeded the driver
must verify that the stop-firmware mailbox command completes
successfully. In the event of a failure, the driver
attempts a shutdown-retry after resetting the ISP and
re-executing firmware.

CCISS was producing warnings about shifts being greater than the size of

because it's calling do_div on a 32-bit quantity. Upon further
investigation, the sector_t total_size is being assigned to an int, and
then we're calling do_div on that int. Obviously, sector_div is called for
here, and I took the chance to refactor the code a little.

Found the problem, I believe: an object lesson in the need for great
caution using ++.

Since the ++ is used as post-increment, the increment is not included
in free_index, and so the added line effectively reverts the
increment. The produced_index side has an analagous bug.
The following change corrects this:
The recent commit 751ae21c6c introduced
a bug in the producer/consumer index calculation in the ibmveth driver
- incautious use of the post-increment ++ operator resulted in an
increment being immediately reverted. This patch corrects the logic.
Without this patch, the driver oopses almost immediately after
activation on at least some machines.

changes due to qe_lib changes include:
o removed inclusion of platform header file
o removed platform_device code, replaced with of_device
o removed typedefs
o uint -> u32 conversions
o removed following defines:
QE_SIZEOF_BD, BD_BUFFER_ARG, BD_BUFFER_CLEAR, BD_BUFFER,
BD_STATUS_AND_LENGTH_SET, BD_STATUS_AND_LENGTH, and BD_BUFFER_SET
because they hid sizeof/in_be32/out_be32 operations from the reader.
o removed irrelevant comments, added others to resemble removed BD_ defines
o const'd and uncasted all get_property() assignments
bugfixes, courtesy of Scott Wood, include:
- Read phy_address as a u32, not u8.
- Match on type == "network" as well as compatible == "ucc_geth", as
device_is_compatible() will only compare up to the length of the
test string, allowing "ucc_geth_phy" to match as well.
- fixes the MAC setting code in ucc_geth.c. The old code was overwriting and dereferencing random stack contents.

The reason sky2 driver was locking up on transmit on the Yukon-FE chipset
is that it was misconfiguring the internal RAM buffer so the transmitter
and receiver were sharing the same space.
The code assumed there was 16K of RAM on Yukon-FE (taken from vendor driver
sk98lin which is even more f*cked up on this). Then it assigned based on that.
The giveaway was that the registers would only hold 9bits so both RX/TX
had 0..1ff for space. It is a wonder it worked at all!
This patch addresses this, and fixes an easily reproducible hang on Transmit.
Only the Yukon-FE chip is Marvell 88E803X (10/100 only) are affected.

I wrote a patch to avoid redundant memory hot-add call at boot time. This
was cause of strange fail message of memory hotplug like "ACPI: add_memory
failed". Memory is recognized by early boot code with EFI/E820.
But, if DSDT describes memory devices for them, then hot-add code is called
for already recognized memory, and it shows fail messages with -EEXIST.
So, sys admin will misunderstand this message as something wrong by it.
This patch avoids them by preventing redundant hot-add call until
completion of driver initialization.

the return value of acpi_processor_get_power_info_fadt is not assigned to
"result" in the case that acpi_processor_get_power_info_cst returns

is the case on this machine), we incorrectly exit the function with -ENODEV
after reading the FADT. The attached patch sets the value of result so

Problem:
New Dell PowerEdge servers have 2 embedded ethernet ports, which are
labeled NIC1 and NIC2 on the chassis, in the BIOS setup screens, and
in the printed documentation. Assuming no other add-in ethernet ports
in the system, Linux 2.4 kernels name these eth0 and eth1
respectively. Many people have come to expect this naming. Linux 2.6
kernels name these eth1 and eth0 respectively (backwards from
expectations). I also have reports that various Sun and HP servers
have similar behavior.
Root cause:
Linux 2.4 kernels walk the pci_devices list, which happens to be
sorted in breadth-first order (or pcbios_find_device order on i386,
which most often is breadth-first also). 2.6 kernels have both the
pci_devices list and the pci_bus_type.klist_devices list, the latter
is what is walked at driver load time to match the pci_id tables; this
klist happens to be in depth-first order.
On systems where, for physical routing reasons, NIC1 appears on a
lower bus number than NIC2, but NIC2's bridge is discovered first in
the depth-first ordering, NIC2 will be discovered before NIC1. If the
list were sorted breadth-first, NIC1 would be discovered before NIC2.
A PowerEdge 1955 system has the following topology which easily
exhibits the difference between depth-first and breadth-first device
lists.
-[0000:00]-+-00.0 Intel Corporation 5000P Chipset Memory Controller Hub
+-02.0-[0000:03-08]--+-00.0-[0000:04-07]--+-00.0-[0000:05-06]----00.0-[0000:06]----00.0 Broadcom Corporation NetXtreme II BCM5708S Gigabit Ethernet (labeled NIC2, 2.4 kernel name eth1, 2.6 kernel name eth0)
+-1c.0-[0000:01-02]----00.0-[0000:02]----00.0 Broadcom Corporation NetXtreme II BCM5708S Gigabit Ethernet (labeled NIC1, 2.4 kernel name eth0, 2.6 kernel name eth1)
Other factors, such as device driver load order and the presence of
PCI slots at various points in the bus hierarchy further complicate
this problem; I'm not trying to solve those here, just restore the
device order, and thus basic behavior, that 2.4 kernels had.
Solution:
The solution can come in multiple steps.
Suggested fix#1: kernel
Patch below optionally sorts the two device lists into breadth-first
ordering to maintain compatibility with 2.4 kernels. It adds two new
command line options:
pci=bfsort
pci=nobfsort
to force the sort order, or not, as you wish. It also adds DMI checks
for the specific Dell systems which exhibit "backwards" ordering, to
make them "right".
Suggested fix#2: udev rules from userland
Many people also have the expectation that embedded NICs are always
discovered before add-in NICs (which this patch does not try to do).
Using the PCI IRQ Routing Table provided by system BIOS, it's easy to
determine which PCI devices are embedded, or if add-in, which PCI slot
they're in. I'm working on a tool that would allow udev to name
ethernet devices in ascending embedded, slot 1 .. slot N order,
subsort by PCI bus/dev/fn breadth-first. It'll be possible to use it
independent of udev as well for those distributions that don't use
udev in their installers.
Suggested fix#3: system board routing rules
One can constrain the system board layout to put NIC1 ahead of NIC2
regardless of breadth-first or depth-first discovery order. This adds
a significant level of complexity to board routing, and may not be
possible in all instances (witness the above systems from several
major manufacturers). I don't want to encourage this particular train
of thought too far, at the expense of not doing #1 or #2 above.
Feedback appreciated. Patch tested on a Dell PowerEdge 1955 blade
with 2.6.18.
You'll also note I took some liberty and temporarily break the klist
abstraction to simplify and speed up the sort algorithm. I think
that's both safe and appropriate in this instance.

The ACPIPnP implementation had the understanding of Linux resource flags very
wrong, resulting in a nonfunctional implementation of DMA resource
allocation.
This was usually not a problem, since almost no on-board PnP devices use ISA
DMA, with the exception of ECP parallel ports. Even with that, parallel port
DMA is preconfigured by the BIOS, so this routine isn't normally called.
Except in the case where somebody does 'rmmod parport_pc; modprobe
parport_pc', where the rmmod case disables the ECP parallel port resources,
and they need to be enabled again to initialize the module. This didn't
work, resulting in a non-printing printer.
The application doing exactly the above to force reprobing of printers is
the YaST printer module. Thus without this fix YaST wedged the printer when
configuring it, and was not able to print a test page.

pci_fixup_video turns into generic code because there are many platforms need this fixup
for embedded VGA as well as x86. The Video BIOS integrates into System BIOS on a machine
has embedded VGA although embedded VGA generally don't have PCI ROM. As a result,
embedded VGA need the way that the sysfs rom points to the Video BIOS of System
RAM (0xC0000). PCI-to-PCI Bridge Architecture specification describes the condition whether
or not PCI ROM forwards VGA compatible memory address. fixup_video suits this specification.
Although the Video ROM generally implements in x86 code regardless of platform, some
application such as X Window System can run this code by dosemu86. Therefore,
pci_fixup_video should turn into generic code.

The most recent VIA IRQ quirk changes have broken various VIA devices for
some users. We are not able to add these devices to the blacklist as they
are also available in PCI-card form, and running the quirk on these devices
brings us back to square one (running the VIA quirk on non-VIA boards where
the quirk is not needed).
This patch, based on suggestions from Sergey Vlasov, implements a scheme
similar to but more restrictive than the scheme we had in 2.6.16 and
earlier. It runs the quirk on all VIA hardware, but *only* if a VIA
southbridge was detected on the system.
To further reduce the amount of quirked devices, this patch includes a
change suggested by Linus at http://lkml.org/lkml/2005/9/27/113 This
ensures that devices bound to non-legacy IO-APIC interrupt lines are not
quirked. We have made one change to Linus' suggestion: we do a comparison
of ">15" rather than ">=15", as 15 is still in the legacy interrupt range.
There is still a downside to this patch: if the user inserts a VIA PCI card
into a VIA-based motherboard, in some circumstances the quirk will also run
on the VIA PCI card. This corner case is hard to avoid.

extract() and implement() have brain damaged attempts to handle 32-bit wide
"fields".
The problem is the index math in the original code didn't clear all the
relevant bits. (offset >> 5) only compensated for 32-bit index. We need
(offset >> 6) if we want to use 64-bit loads.
But it was also wrong in that it tried to use quasi-aligned loads. Ie
"report" was only incremented in multiples of 4 bytes and then the offset
was masked off for values greater than 4 bytes. The right way is to
pretend "report" points at a byte array. And offset is then only minor
adjustment for < 8 bits of offset. "n" (field width) can then be as big as
24 (assuming 32-bit loads) since "offset" will never be bigger than 7.
If someone needs either function to handle more than 24-bits, please
document why - point at a specification or specific USB hid device - in
comments in the code.
extract/implement() are also an eyesore to read. Please banish whoever
wrote it to read CodingStyle 3 times in a row to a classroom full of 1st
graders armed with rubberbands. Or just flame them. Whatever. Globbing
all the code together on two lines does NOT make it faster and is Just

The speedtouch modem setup code was reverse engineered many years
ago from a prehistoric windows driver. Less ancient windows drivers,
even those from a few years ago, perform extra initialization steps
which this patch adds to the linux driver. David Woodhouse observed
that this initialization along with the firmware bin/sachu3/zzzlp2.eni
from the driver at
http://www.speedtouch.co.uk/downloads/330/301/UK3012%20Extended.zip
improves line sync speeds by about 20%. He provided the original
patch, which I've modified to use symbolic names (BMaxDSL, ModemMode,
ModemOption) rather than magic numbers. These names may not seem like
much of an improvement (after all, what is "ModemOption" exactly?),
but they do have one big advantage: they are the names used in the
windows registry. I've made them available as module parameters.
Thanks are due to Aurelio Arroyo, who noticed the relationship
between these magic numbers and the entries in Phonebook.ini.

* Root hub irq enable call
* Shutdown hook for usbcore
Plus usb_bus.hcpriv has now been removed from usbcore.

The patch below is a necessary workaround to support the BT On-Air USB modem, which
fails to initialise properly during normal probing thus:
Sep 30 17:34:57 sled kernel: drivers/usb/class/cdc-acm.c: Zero length descriptor references
Sep 30 17:34:57 sled kernel: cdc_acm: probe of 1-1.2:1.0 failed with error -22
Adding the patch below causes the probing section to be skipped, and the modem
then initialises correctly.

this patch converts two if () BUG(); construct to BUG_ON();
which occupies less space, uses unlikely and is safer when
BUG() is disabled.
