7510873d86 [BNX2]: Fix Xen problem.
This fixes the problem of not receiving packets in the Xen bridging
environment.  The Xen script sets the device's MAC address to
FE:FF:FF:FF:FF:FF and puts the device in promiscuous mode.  The
firmware had problem receiving all packets in this configuration.

New firmware and setting the PROM_VLAN bit when in promiscuous mode
will fix this problem.

58a5a7b955 [NET]: Conditionally use bh_lock_sock_nested in sk_receive_skb
Spotted by Ian McDonald, tentatively fixed by Gerrit Renker:

http://www.mail-archive.com/dccp%40vger.kernel.org/msg00599.html

Rewritten not to unroll sk_receive_skb, in the common case, i.e. no lock
debugging, its optimized away.

5de4a473bd netpoll queue cleanup
The beast had a long and not very happy history. At one
point, a friend (netdump) had asked that he open up a little.
Well, the friend was long gone now, and the beast had
this dangling piece hanging (netpoll_queue).

It wasn't hard to stitch the netpoll_queue back in
where it belonged and make everything tidy.

	If E1 has a signed type and a negative value, the resulting value

e8a2b6a420 [PATCH] PHY: Add support for configuring the PHY connection interface
Most PHYs connect to an ethernet controller over a GMII or MII
interface.  However, a growing number are connected over
different interfaces, such as RGMII or SGMII.

The ethernet driver will tell the PHY what type of connection it
is by setting it manually, or passing it in through phy_connect
(or phy_attach).

Changes include:
* Updates to documentation
* Updates to PHY Lib consumers
* Changes to PHY Lib to add interface support
* Some minor changes to whitespace in phy.h
* gianfar driver now detects interface and passes appropriate
  value to PHY Lib

assertions. Keep in mind that the ZD_ASSERT() macro only results in code,
if DEBUG is defined.

http://bugzilla.kernel.org/show_bug.cgi?id=7399

zd1211rw's support for IW_FREQ_AUTO is broken: when specified, the driver
tries to change to a channel specified in an uninitialized integer. As
IW_FREQ_AUTO is hard to implement properly, the solution (at least for now)
is to drop support for it and start ignoring the flags like all other wireless
drivers do.

This has the added advantage that kismet also starts working with zd1211rw,
even though kismet requesting IW_FREQ_AUTO is also a bug (fixed in their svn)

89e5785fc8 [PATCH] Atmel MACB ethernet driver
Driver for the Atmel MACB on-chip ethernet module.

Tested on AVR32/AT32AP7000/ATSTK1000. I've heard rumours that it works
with AT91SAM9260 as well, and it may be possible to share some code with
the at91_ether driver for AT91RM9200.

Hardware documentation can be found in the AT32AP7000 data sheet,
which can be downloaded from

http://www.atmel.com/dyn/products/datasheets.asp?family_id=682

Changes since previous version:
  * Probe for PHY ID instead of depending on it being provided through
    platform_data.
  * Grab initial ethernet address from the MACB registers instead
    of depending on platform_data.
  * Set MII/RMII mode correctly.

These changes are mostly about making the driver more compatible with
the at91 infrastructure.

5e123b844a [PATCH] Add tsi108/9 On Chip Ethernet device driver support
Add tsi108/9 on chip Ethernet controller driver support.

The driver code collects the feedback of previous posting form the mailing
list and gives the update.

MPC7448HPC2 platform in arch/powerpc uses tsi108 bridge.

The following is a brief description of the Ethernet controller:

The Tsi108/9 Ethernet Controller connects Switch Fabric to two independent
Gigabit Ethernet ports,E0 and E1.  It uses a single Management interface to
manage the two physical connection devices (PHYs).  Each Ethernet port has
its own statistics monitor that tracks and reports key interface
statistics.  Each port supports a 256-entry hash table for address
filtering.  In addition, each port is bridged to the Switch Fabric through
a 2-Kbyte transmit FIFO and a 4-Kbyte Receive FIFO.

Each Ethernet port also has a pair of internal Ethernet DMA channels to
support the transmit and receive data flows.  The Ethernet DMA channels use
descriptors set up in memory, the memory map of the device, and access via
the Switch Fabric.  The Ethernet Controller’s DMA arbiter handles
arbitration for the Switch Fabric.  The Controller also has a register bus
interface for register accesses and status monitor control.

The PMD (Physical Media Device) interface operates in MII, GMII, or TBI
modes.  The MII mode is used for connecting with 10 or 100 Mbit/s PMDs.
The GMII and TBI modes are used to connect with Gigabit PMDs.  Internal
data flows to and from the Ethernet Controller through the Switch Fabric.
Each

Ethernet port uses its transmit and receive DMA channels to manage data
flows through buffer descriptors that are predefined by the system (the
descriptors can exist anywhere in the system memory map).  These
descriptors are data structures that point to buffers filled with data
ready to transmit over Ethernet, or they point to empty buffers ready to
receive data from Ethernet.

08c3103a56 [PATCH] bcm43xx: remove badness variable and related routine
When the periodic work function in bcm43xx was converted for voluntary preemption
to reduce latency, a new function was created to estimate the "badness" of
each step, and this quantity was used to determine if preemption should be
enabled when periodic work was undertaken. This concept was quite useful
while debugging of periodic work was in progress. Now that this routine
seems to be working correctly, it is time to simplify the code. This
patch keeps the functionality intact, but simplifies the code.

  plugging in the link didn't autonegotiate.  Now the AN state
  detects the lack of link, and enters the NO_LINK state.  AN

835bb12983 e1000: add dynamic itr modes
Add a new dynamic itr algorithm, with 2 modes, and make it the default
operation mode. This greatly reduces latency and increases small packet
performance, at the "cost" of some CPU utilization. Bulk traffic
throughput is unaffected.

The driver can limit the amount of interrupts per second that the
adapter will generate for incoming packets. It does this by writing a
value to the adapter that is based on the maximum amount of interrupts
that the adapter will generate per second.

Setting InterruptThrottleRate to a value greater or equal to 100 will
program the adapter to send out a maximum of that many interrupts per
second, even if more packets have come in. This reduces interrupt
load on the system and can lower CPU utilization under heavy load,
but will increase latency as packets are not processed as quickly.

The default behaviour of the driver previously assumed a static
InterruptThrottleRate value of 8000, providing a good fallback value
for all traffic types,but lacking in small packet performance and
latency. The hardware can handle many more small packets per second
however, and for this reason an adaptive interrupt moderation algorithm
was implemented.

Since 7.3.x, the driver has two adaptive modes (setting 1 or 3) in
which it dynamically adjusts the InterruptThrottleRate value based on
the traffic that it receives. After determining the type of incoming
traffic in the last timeframe, it will adjust the InterruptThrottleRate
to an appropriate value for that traffic.

The algorithm classifies the incoming traffic every interval into
classes.  Once the class is determined, the InterruptThrottleRate
value is adjusted to suit that traffic type the best. There are
three classes defined: "Bulk traffic", for large amounts of packets
of normal size; "Low latency", for small amounts of traffic and/or
a significant percentage of small packets; and "Lowest latency",
for almost completely small packets or minimal traffic.

In dynamic conservative mode, the InterruptThrottleRate value is
set to 4000 for traffic that falls in class "Bulk traffic". If
traffic falls in the "Low latency" or "Lowest latency" class, the
InterruptThrottleRate is increased stepwise to 20000. This default
mode is suitable for most applications.

For situations where low latency is vital such as cluster or
grid computing, the algorithm can reduce latency even more when
InterruptThrottleRate is set to mode 1. In this mode, which operates
the same as mode 3, the InterruptThrottleRate will be increased
stepwise to 70000 for traffic in class "Lowest latency".

Setting InterruptThrottleRate to 0 turns off any interrupt moderation
and may improve small packet latency, but is generally not suitable
for bulk throughput traffic.

d18e0c4a54 [PATCH] prism54: fix potential race in reset scheduling
NET: prism54 - fix potential race in reset scheduling

There appears to be a race in reset scheduling logic - thread
responsible for reseting the interface should clear "reset
pending" flag before restarting the queue, otherwise timeout
handler might not schedule another reset even if it is needed.

This race is mostly theoretical as far as I can see but a race
nonetheless.

c9308b06c0 [PATCH] ieee80211: Move IV/ICV stripping into ieee80211_rx
This patch adds a host_strip_iv_icv flag to ieee80211 which indicates that
ieee80211_rx should strip the IV/ICV/other security features from the payload.
This saves on some memmove() calls in the driver and seems like something that
belongs in the stack as it can be used by bcm43xx, ipw2200, and zd1211rw

I will submit the ipw2200 patch separately as it needs testing.

This patch also adds some sensible variable reuse (idx vs keyidx) in

6c3561b0c1 [PATCH] beginning of 8390 fixes - generic and arm/etherh
etherh and a handful of other odd drivers use different macros when building
8390.c.  Since we generate a single 8390.o and then link with it, in any
config with both oddball and normal 8390-based driver we will end up with
breakage in at least one of them.  Solution: take most of 8390.c into
lib8390.c and have 8390.c, etherh.c and the rest of oddballs #include it.
Helper macros are taken from 8390.h to whoever includes lib8390.c.  That
way odd drivers get separate instances of compiled 8390 stuff and stop
stepping on each other's toes.  8390.h gets cleaned up - we don't have
the cascade of ifdefs in there and are left with the stuff that can be
used by any 8390-based driver.  Current problems are exactly because of
that cascade - we attempt to choose the set of helpers by looking at config
and that, of course, doesn't work well when we have several sets needed
by various drivers in our config.

So I'd very much like to see (at least partial, with msi disabled)
suspend support for forcedeth in mainline.

3c3070d713 [PATCH] 2.6.18: sb1250-mac: Phylib IRQ handling fixes
This patch fixes a couple of problems discovered with interrupt handling
in the phylib core, namely:

1. The driver uses timer and workqueue calls, but does not include
   <linux/timer.h> nor <linux/workqueue.h>.

2. The driver uses schedule_work() for handling interrupts, but does not
   make sure any pending work scheduled thus has been completed before
   driver's structures get freed from memory.  This is especially
   important as interrupts may keep arriving if the line is shared with
   another PHY.

   The solution is to ignore phy_interrupt() calls if the reported device
   has already been halted and calling flush_scheduled_work() from
   phy_stop_interrupts() (but guarded with current_is_keventd() in case
   the function has been called through keventd from the MAC device's
   close call to avoid a deadlock on the netlink lock).

2dec7555e6 [PATCH] sata_nv: fix ATAPI in ADMA mode
The attached patch against 2.6.19-rc6-mm1 fixes some problems in sata_nv
with ATAPI devices on controllers running in ADMA mode. Some of the
logic in the nv_adma_bmdma_* functions was inverted causing a bunch of
warnings and caused those functions not to work properly. Also, when an
ATAPI device is connected, we need to use the legacy DMA engine. The
code now disables the PCI configuration register bits for ADMA so that
this works, and ensures that no ATAPI DMA commands go through until this
is done.

b2d1eee1e9 [PATCH] sata_promise fixes and updates
This patch updates the sata_promise driver as follows:
- Correct typo in definition of PDC_TBG_MODE: it's at 0x41C not 0x41
  in first-generation chips. This error caused PCI access alignment
  exceptions on SPARC64, and on all platforms it disabled the expected
  initialisation of TBG mode.
- Add flags field to struct pdc_host_priv. Define PDC_FLAG_GEN_II
  and use it to distinguish first- and second-generation chips.
- Prevent the FLASH_CTL FIFO_SHD bit from being set to 1 on second-
  generation chips. This matches Promises' ulsata2 driver.
- Prevent TBG mode and SLEW rate initialisation in second-generation chips.
  These two registers have moved, TBG mode has been redefined, and
  Promise's ulsata2 driver no longer attempts to initialise them.
- Correct PCI device table so devices 0x3570, 0x3571, and 0x3d73 are
  marked as 2057x (2nd gen) not 2037x (1st gen).
- Correct PCI device table so device 0x3d17 is marked as 40518
  (2nd gen 4 ports) not 20319 (1st gen 4 ports).
- Correct pdc_ata_init_one() to treat 20771 as a second-generation chip.

Tested on 0x3d75 (2nd gen), 0x3d73 (2nd gen), and 0x3373 (1st gen) chips.
The information comes from the newly uploaded Promise SATA HW specs,
Promise's ultra and ulsata2 drivers, and debugging on 3d75/3d73/3373 chips.

hp->hotplug_offset could now be removed and its value recomputed
in pdc_host_init() using hp->flags, but that would be a cleanup
not a functional change, so I'm ignoring it for now.

39599a5334 [PATCH] libata: sync result_tf.flags w/ command tf.flags
libata didn't initialize result_tf.flags which indicates transfer type
(RW/FUA) and address type (CHS/LBA/LBA48).  ata_gen_fixed_sense()
assumed result_tf.flags equals command tf.flags and failed to report
the first failed block to SCSI layer because zero tf flags indicates
CHS and bad block reporting for CHS is not implemented.

Implement fill_result_tf() which sets result_tf.flags to command
tf.flags and use it to fill result_tf.

228c1590be [PATCH] ata_piix: apply device detection via polling IDENTIFY
PATA PIIX uses reset signature + TF r/w test for device presence
detection, which doesn't always work.  It sometimes reports phantom
device which results in IDENTIFY timeouts.

SATA PIIX uses some combination of PCS + reset signature + TF r/w test
for device presence detection.  No combination satifies all and for
some controllers, there doesn't seem to be any combination which
works reliably.

This patch makes both PATA and SATA piix's use reset signature + TF
r/w + polling IDENTIFY for device detection.  This is what the old
libata (before irq-pio and new EH) did and what IDE does.

This patch also removes now obsolete PIIX_FLAG_IGNORE_PCS, force_pcs
and related code.

55a8e2c83c [PATCH] libata: implement presence detection via polling IDENTIFY
On some controllers (ICHs in piix mode), there is *NO* reliable way to
determine device presence other than issuing IDENTIFY and see how the
transaction proceeds by watching the TF status register.

libata acted this way before irq-pio and phantom devices caused very
little problem but now that IDENTIFY is performed using IRQ drive PIO,
such phantom devices now result in multiple 30sec timeouts during
boot.

This patch implements ATA_FLAG_DETECT_POLLING.  If a LLD sets this
flag, libata core issues the initial IDENTIFY in polling mode and if
the initial data transfer fails w/ HSM violation, the port is
considered to be empty thus replicating the old libata and IDE
behavior.

6fc49adb94 [PATCH] libata: use FLUSH_EXT only when driver is larger than LBA28 limit
Many drives support LBA48 even when its capacity is smaller than
1<<28, as LBA48 is required for many functionalities.  FLUSH_EXT is
mandatory for drives w/ LBA48 support.

Interestingly, at least one of such drives (ST960812A) has problems
dealing with FLUSH_EXT.  It eventually completes the command but takes
around 7 seconds to finish in many cases thus drastically slowing down
IO transactions.  This seems to be a firmware bug which sneaked into
production probably because no other ATA driver including linux IDE
issues FLUSH_EXT to drives which report support for LBA48 & FLUSH_EXT
but is smaller than 1<<28 blocks.

This patch adds ATA_DFLAG_FLUSH_EXT which is set iff the drive
supports LBA48 & FLUSH_EXT and is larger than LBA28 limit.  Both cache
flush paths are updated to issue FLUSH_EXT only when the flag is set.
Note that the changed behavior is more inline with the rest of libata.
libata prefers shorter commands whenever possible.

baa1e78a83 [PATCH] libata: implement ATA_EHI_SETMODE and ATA_EHI_POST_SETMODE
libata EH used to perform ata_set_mode() iff the EH session performed
reset as indicated by ATA_EHI_DID_RESET.  This is incorrect because
->dev_config() called by revalidation is allowed to modify transfer
mode which ata_set_mode() should take care of.  This patch implements
the following two flags.

* ATA_EHI_SETMODE: set during EH to schedule ata_set_mode().  Both new
  device attachment and revalidation set this flag.

* ATA_EHI_POST_SETMODE: set while the device is revalidated after
  ata_set_mode().  Post-setmode revalidation is different from initial
  configuaration and EH revalidation in that ->dev_config() is not
  allowed tune transfer mode.  LLD can use this flag to determine
  whether it's allowed to tune transfer mode.  Note that POST_SETMODE
  ->dev_config() is guaranteed to be preceded by non-POST_SETMODE
  ->dev_config().

libata waits for !BSY even when the status register reports 0xff.
This causes long boot delays when D8 isn't pulled down properly.  This
patch does the followings.

* don't wait if status register is 0xff in all wait functions

* make ata_busy_sleep() return 0 on success and -errno on failure.
  -ENODEV is returned on 0xff status and -EBUSY on other failures.

* make ata_bus_softreset() succeed on 0xff status.  0xff status is not
  reset failure.  It indicates no device.  This removes unnecessary
  retries on such ports.  Note that the code change assumes unoccupied
  port reporting 0xff status does not produce valid device signature.

c67334fbdf Driver core: platform_driver_probe(), can save codespace
This defines a new platform_driver_probe() method allowing the driver's
probe() method, and its support code+data, to safely live in __init
sections for typical system configurations.

Many system-on-chip processors could benefit from this API, to the tune
of recovering hundreds to thousands of bytes per driver.  That's memory
which is currently wasted holding code which can never be called after
system startup, yet can not be removed.   It can't be removed because of
the linkage requirement that pointers to init section code (like, ideally,
probe support) must not live in other sections (like driver method tables)
after those pointers would be invalid.

8a82472f86 driver core: Introduce device_move(): move a device to a new parent.
Provide a function device_move() to move a device to a new parent device. Add
auxilliary functions kobject_move() and sysfs_move_dir().
kobject_move() generates a new uevent of type KOBJ_MOVE, containing the
previous path (DEVPATH_OLD) in addition to the usual values. For this, a new
interface kobject_uevent_env() is created that allows to add further
environmental data to the uevent at the kobject layer.

06a4bcae1f cpu topology: consider sysfs_create_group return value
Take return value of sysfs_create_group() into account.  That function got
called in case of CPU_ONLINE notification.  Since callbacks are not allowed
to fail on CPU_ONLINE notification do the sysfs group creation on
CPU_UP_PREPARE notification.

Also remember if creation succeeded in a bitmask.  So it's possible to know
whether it's legal to call sysfs_remove_group or not.

In addition some other minor stuff:

- since CPU_UP_PREPARE might fail add CPU_UP_CANCELED handling as well.
- use hotcpu_notifier instead of register_hotcpu_notifier.
- #ifdef code that isn't needed in the !CONFIG_HOTPLUG_CPU case.

2895353346 Driver core: Call platform_notify_remove later
Move the call to platform_notify_remove() to after the call to
bus_remove_device(), where it belongs.  It's bogus to notify the platform
of removal while drivers are still attached to the device and possibly
still operating since the platform might use this callback to tear down
some resources used by the driver (ACPI bits, iommu table, ...)

465ae641e4 ACPI: Change ACPI to use dev_archdata instead of firmware_data
Change ACPI to use dev_archdata instead of firmware_data

This patch changes ACPI to use the new dev_archdata on i386, x86_64
and ia64 (is there any other arch using ACPI ?) to store it's
acpi_handle.

It also removes the firmware_data field from struct device as this
was the only user.

Only build-tested on x86
