Third rendition of FireWire OHCI 1.0 Isochronous Receive support, using a
zer-copy method similar to OHCI 1.1 which puts the IR data payload directly
into the userspace buffer. The zero-copy implementation eliminates the
video artifacts, audio popping, and buffer underrun problems seen with
version 1 of this patch, as well as fixing a regression in OHCI 1.1 support
introduced by version 2 of this patch.
Successfully tested in OHCI 1.1 mode on the following chipsets:
- NEC uPD72847 (rev 01), OHCI 1.1 (PCI)
- Ti XIO2200(A) (rev 01), OHCI 1.1 (PCIe)
- Ti TSB41AB2 (rev 01), OHCI 1.1 (PCI on SB Audigy)
- Apple UniNorth 2 (rev 81), OHCI 1.1 (PowerBook G4 onboard)
Successfully tested in OHCI 1.0 mode on the following chipsets:
- Agere FW323 (rev 06), OHCI 1.0 (Mac Mini onboard)
- Agere FW323 (rev 06), OHCI 1.0 (PCI)
- Via VT6306 (rev 46), OHCI 1.0 (PCI)
- NEC OrangeLink (rev 01), OHCI 1.0 (PCI)
- NEC uPD72847 (rev 01), OHCI 1.1 (PCI)
- Ti XIO2200(A) (rev 01), OHCI 1.1 (PCIe)
The bulk of testing was done in an x86_64 system, but was also successfully
sanity-tested on other systems, including a PPC(32) PowerBook G4 and an i686
EPIA M10k. Crude benchmarking (watching top during capture) puts the cpu
utilization during capture on the EPIA's 1GHz Via C3 processor around 13%,
which is down from 30% with the v1 code.
Some implementation details:
To maintain the same userspace API as dual-buffer mode, we set up two
descriptors for every incoming packet. The first is an INPUT_MORE descriptor,
pointing to a buffer large enough to hold just the packet's iso headers,
immediately followed by an INPUT_LAST descriptor, pointing to a chunk of the
userspace buffer big enough for the packet's data payload. With this setup,
each incoming packet fills in these two descriptors in a manner that very
closely emulates dual-buffer receive, to the point where the bulk of the
handle_ir_* code is now identical between the two (and probably primed for
some restructuring to share code between them).
The only caveat I have at the moment is that neither of my OHCI 1.0 Via
VT6307-based FireWire controllers work particularly well with this code
for reasons I have yet to figure out.

Spurious NCQ completion detection implemented in ahci was incorrect.
On AHCI receving and processing FISes and raising interrupts are not
interlocked and spurious interrupts are expected.
For example, if an interrupt occurs while interrupt handler is running
and the running interrupt handler handles the event the new IRQ
indicated, after IRQ handler finishes, it will be executed again
because IRQ pending bit is set by the new interrupt but there won't be
anything to process.
Please read the following message for more information.
http://article.gmane.org/gmane.linux.ide/26012
This patch...
* Removes all spurious IRQ whining from ahci. Spurious NCQ completion
detection was completely wrong. Spurious D2H Register FIS taught us
that some early drives send spurious D2H Register FIS with I bit set
while NCQ commands are in progress but none of recent drives does
that and even the ones which show such behavior can do NCQ fine.
* Kills all NCQ blacklist entries which were added because of spurious
NCQ completions. I tracked down each commit and verified all
removed ones are actually added because of spurious completions.
WD740ADFD-00NLR1 wasn't deleted but moved upward because the drive
not only had spurious NCQ completions but also is slow on sequential
data transfers if NCQ is enabled.
Maxtor 7V300F0 was added by 0e3dbc01d5
from Alan Cox. I can only find evidences that the drive only had
troubles with spuruious completions by searching the mailing list.
This entry needs to be verified and removed if it doesn't have other
NCQ related problems.

With some PHYs, when the link goes away, the EMAC reset fails due
to the loss of the RX clock I believe.
The old EMAC driver worked around that using some internal chip-specific
clock force bits that are different on various 44x implementations.
This is an attempt at doing it differently, by avoiding the reset when
there is no link, but forcing loopback mode instead. It seems to work

Add new hash for balance-xor and 802.3ad modes. Originally
submitted by "Glenn Griffin" <ggriffin.kernel@gmail.com>; modified by
Jay Vosburgh to move setting of hash policy out of line, tweak the
documentation update and add version update to 3.2.2.
Glenn's original comment follows:
Included is a patch for a new xmit_hash_policy for the bonding driver
that selects slaves based on MAC and IP information. This is a middle
ground between what currently exists in the layer2 only policy and the
layer3+4 policy. This policy strives to be fully 802.3ad compliant by
transmitting every packet of any particular flow over the same link.
As documented the layer3+4 policy is not fully compliant for extreme
cases such as ip fragmentation, so this policy is a nice compromise
for environments that require full compliance but desire more than the
layer2 only policy.

0000000 e t h - l e f t e t h - r i g
0000020 h t \n \0
0000025
It mostly entails deleting '+1'-s after sprintf() calls: the return value
of sprintf is the number of characters printed, without the closing NUL,
ie. exactly what the sysfs interface requires. The three multivalue
cases are different, because they also have to swallow back a trailing

Changed resolution of named references in packages
Fixed a problem with the Package operator where all named
references were created as object references and left otherwise
unresolved. According to the ACPI specification, a Package can
only contain Data Objects or references to control methods. The
implication is that named references to Data Objects (Integer,
Buffer, String, Package, BufferField, Field) should be resolved
immediately upon package creation. This is the approach taken
with this change. References to all other named objects (Methods,
Devices, Scopes, etc.) are all now properly created as reference objects.

sata_mv: Fix broken Marvell 7042 support.
The Marvell 7042 chip is more or less the same as the 6042 internally,
but sports a PCIe bus. Despite having identical SATA cores, the 7042
does differ from its PCI bus counterparts in placment and layout of
certain bus related registers.
This patch fixes sata_mv to distinguish between the PCI bus registers
of earlier chips, and the PCIe bus registers of the 7042.
Specifically, move the offsets and bit patterns for the
PCI/PCIe interrupt cause/mask registers into the struct mv_host_priv,
as these values differ between the 6xxx and 7xxx series chips.
This fixes the driver to not access reserved PCI addresses,
and prevents the lockups reported in linux-2.6.24 with 7042 boards.
Also add a new PCI ID for the Highpoint 2300 7042-based board
that I'm using for testing this stuff here.

The driver would not work over fibre if other end when down then
came back up (would require reloading driver). The correct way
to manage the link the same way for both TP and fibre.

The calculation of usable FIFO RAM is wrong in the skge driver.
First, is doesn't take into account the reserved area on the original
SysKonnect Genesis boards. Second it has an off-by-one error because
hw->ports is either 1 or 2.

Currently ctc-device initialization is broken (kernel bug in
ctc_new_device).
The new network namespace code reveals a deficiency of the
ctc driver. It should make use of alloc_netdev() as described
in Documentation/networking/netdevices.txt.

Fix the case when the card initialization fails on a mtu change and then
close is called (due to ifdown), which frees non existent rx buffers.
- Returning appropriate error codes in init_nic function.
- In s2io_close function s2io_card_down is called only when device is up.
- In s2io_change_mtu function return value of s2io_card_up function
is checked and returned if it failed.

IB/ehca: Fix static rate if path faster than link
IPoIB: Fix oops if xmit is called when priv->broadcast is NULL
The formula would yield -1 if the path is faster than the link, which
is wrong in a bad way (max throttling). Clamp to 0, which is the
correct value.

lbs_mac_event_disconnected() was called once and then never again
upon a hardware MAC event.
The reason was that the driver didn't clean the correct bit in the interrupt
cause register of the chip.

I'm not sure why it was doing this, and I'm not sure I _want_ to know
why. But calling it NETIF_F_DYNALLOC doesn't change the fact that the
kernel believes it to be NETIF_F_IPV6_CSUM, and that IPv6 communication
is hence buggered.
