073a24364f s2io: Formatting log message
S2IO driver is printing dev->name before the name being allocated, which
display eth%d instead of eth0, eth1, etc. Example: 

eth%d: Enabling MSIX failed
eth%d: MSI-X requested but failed to enable

This patch just change eth%d to s2io.

67dd82462d hso: add new device id's
This patch adds a few device ID's. It also removes an ID that was used
in an internal engineering version of a device and will never see
commercial light. Even if this ID will be 'recycled' in the future,
which is very unlikely, we don't know what kind of device will be
behind it. Therefore it's safer to remove it.

1a5645bc90 connector: create connector workqueue only while needed once
The netlink connector uses its own workqueue to relay the datas sent
from userspace to the appropriate callback.  If you launch the test
from Documentation/connector and change it a bit to send a high flow
of data, you will see thousands of events coming to the "cqueue"
workqueue by looking at the workqueue tracer.

This flow of events can be sent very quickly. So, to not encumber the
kevent workqueue and delay other jobs, the "cqueue" workqueue should
remain.

But this workqueue is pointless most of the time, it will always be
created (assuming you have built it of course) although only
developpers with specific needs will use it.

So avoid this "most of the time useless task", this patch proposes to
create this workqueue only when needed once.  The first jobs to be
sent to connector callbacks will be sent to kevent while the "cqueue"
thread creation will be scheduled to kevent too.

The following jobs will continue to be scheduled to keventd until the
cqueue workqueue is created, and then the rest of the jobs will
continue to perform as usual, through this dedicated workqueue.

Each time I tested this patch, only the first event was sent to
keventd, the rest has been sent to cqueue which have been created
quickly.

Also, this patch fixes some trailing whitespaces on the connector files.

9062712fa9 libata: implement HORKAGE_1_5_GBPS and apply it to WD My Book
3Gbps is often much more prone to transmission failures.  It's usually
okay to let EH handle speed down after transmission failures but some
WD My Book drives completely shutdown after certain transmission
failures and after it only power cycling can revive them.  Combined
with the fact that external drives often end up with cable assembly
which is longer than usual and more likely to have intervening gender,
this makes these drives very likely to shutdown under certain
configurations virtually rendering them unusable.

This patch implements HOARKGE_1_5_GBPS and applies it to WD My Book
such that 1.5Gbps is forced once the device is identified.

Please take a look at the following bz for related reports.

cf9a590a9e libata: add no penalty retry request for EH device handling routines
Let -EAGAIN from EH device handling routines trigger EH retry without
consuming its tries count.  This will be used to implement link SPD
horkage which requires hardreset to adjust SPD without affecting other
EH decisions.  As it bypasses the forward progress guarantee provided
by the tries count, the requester is responsible for ensuring forward
progress.

c2c7a89c5e libata: improve probe failure handling
When link is flaky at high speed, it isn't uncommon for a device to
repeatedly fail probing sequence early after successfully negotiating
high link speed.  This often leads to consecutive hotplug events
without successful probing.

This patch improves libata EH such that it remembers probing trials
and if there have been more than two unsuccessful trials in the past
60 seconds, slows down link speed to 1.5Gbps.

As link speed negotiation is the duty of the PHY layer proper, the
goal of this fallback mechanism is to provide the last resort when
everything else fails, which unfortunately happens not too
infrequently, so no fancy 6->3->1.5 speeding down or highest
successful transmission speed seen kind of logics (yet).

99cf610aa4 libata: clear dev->ering in smarter way
dev->ering used to be cleared together with the rest of ata_device in
ata_dev_init() which is called whenever a probing event occurs.
dev->ering is about to be used to track probing failures so it needs
to remain persistent over multiple porbing events.  This patch
achieves this by doing the following.

* Instead of CLEAR_OFFSET, define CLEAR_BEGIN and CLEAR_END and only
  clear between BEGIN and END.  ering is moved after END.  The split
  of persistent area is to allow hotter items remain at the head.

* ering is explicitly cleared on ata_dev_disable() and when device
  attach succeeds.  So, ering is persistent throug a device's life
  time (unless explicitly cleared of course) and also through periods
  inbetween disablement of an attached device and successful detection
  of the next one.

d89293abd9 libata: fix EH device failure handling
The dev->pio_mode > XFER_PIO_0 test is there to avoid unnecessary
speed down warning messages but it accidentally disabled SATA link spd
down during configuration phase after reset where PIO mode is always
zero.

This patch fixes the problem by moving the test where it belongs.
This makes libata probing sequence behave better when the connection
is flaky at higher link speeds which isn't too uncommon for eSATA
devices.

3fff0179e3 virtio-pci: do not oops on config change if driver not loaded
The host really shouldn't be notifying us of config changes
before the device status is VIRTIO_CONFIG_S_DRIVER or
VIRTIO_CONFIG_S_DRIVER_OK.

However, if we do happen to be interrupted while we're not
attached to a driver, we really shouldn't oops. Prevent
this simply by checking that device->driver is non-NULL
before trying to notify the driver of config changes.

Problem observed by doing a "set_link virtio.0 down" with
QEMU before the net driver had been loaded.

has finished, the problem seems to be fixed.

If ricoh_mmc suspends before sdhci_pci, it will pull the card
out from under the controller, which could leave the system in
a very confused state.

Using suspend_late/resume_early ensures that sdhci_pci suspends first

a77dcc437c ide: add CS5536 host driver (v3)
This is a port of libata's pata_cs5536.c (written by Martin K. Petersen)
to IDE subsystem.

Changes done while at it:

* Reprogram PIO/MWDMA timings if needed before and after DMA transfer
  (chipset uses shared PIO/MWDMA timings).

* Fix cable detection to report 80-wires cable if BIOS set it for any
  device on a port (IDE core will do drive-side cable detection later).

* Don't disable UDMA while programming PIO timings.

* Simplify PCI/MSR support.

Pros of having IDE host driver in addition to libata's one:

* IDE is much lighter than SCSI+libata, the host driver itself is also
  a bit smaller:

   text    data     bss     dec     hex filename
   1261     496       4    1761     6e1 drivers/ata/pata_cs5536.o
   1242     128       4    1374     55e drivers/ide/cs5536.o

* This allows use of IDE features which are unavailable under libata.

v2:
* Fixes per review from Sergei:
  - simplify dependency check in Kconfig
  - use IDE_DRV_MASK also for ->drive_data
  - disable UDMA when programming MWDMA
  - program new DTC timings only when necessary
  - fix printk() level in cs5536_init_one()

* Fix patch description according to comments from Alan and Sergei.

v3:
* Smarter masking of UDMA bits per Sergei's suggestion.

7fbb7cadd0 fbdev/atyfb: Fix DSP config on some PowerMacs & PowerBooks
Since the complete re-write in 2.6.10, some PowerMacs (At least PowerMac 5500
and PowerMac G3 Beige rev A) with ATI Mach64 chip have suffered from unstable
columns in their framebuffer image. This seems to depend on a value (4) read
from PLL_EXT_CNTL register, which leads to incorrect DSP config parameters to
be written to the chip. This patch uses a value calculated by aty_init_pll_ct
instead, as a starting point.

There are questions as to whether this should be extended to other platforms
or maybe made dependent on specific chip types, but in the meantime, this has
been tested on various powermacs and works for them so let's commit it.

3d1e4db2b0 phylib: Rework suspend/resume code to check netdev wakeup capability
In most cases (e.g. PCI drivers) MDIO and MAC controllers are
represented by the same device. But for SOC ethernets we have
separate devices. So, in SOC case, checking whether MDIO
controller may wakeup is not only makes little sense, but also
prevents us from doing per-netdevice wakeup management.

This patch reworks suspend/resume code so that now it checks
for net device's wakeup flags, not MDIO controller's ones.

Each netdevice should manage its wakeup flags, and phylib will
decide whether suspend an attached PHY or not.

Some platforms (for example pcm037) do not have an EEPROM fitted,
instead storing their mac address somewhere else.  The bootloader
fetches this and configures the ethernet adapter before the kernel is

This patch allows a platform to indicate to the driver via the

configured via such a mechanism, and should be saved before resetting

On LAN9115/LAN9117/LAN9215/LAN9217, external phys are supported.  These

In some cases it is desirable to override this hardware strap and force
use of either the internal phy or an external PHY.  This patch adds

This patch fixes a memory corruption when UTF-8 console is used and the

a frame line).

When memory redzones are enabled, a redzone corruption is reported.
When they are not enabled, trashing of random memory occurs.

fc8744adc8 Stop playing silly games with the VM_ACCOUNT flag
The mmap_region() code would temporarily set the VM_ACCOUNT flag for
anonymous shared mappings just to inform shmem_zero_setup() that it
should enable accounting for the resulting shm object.  It would then
clear the flag after calling ->mmap (for the /dev/zero case) or doing
shmem_zero_setup() (for the MAP_ANON case).

This just resulted in vma merge issues, but also made for just
unnecessary confusion.  Use the already-existing VM_NORESERVE flag for
this instead, and let shmem_{zero|file}_setup() just figure it out from
that.

This also happens to make it obvious that the new DRI2 GEM layer uses a
non-reserving backing store for its object allocation - which is quite
possibly not intentional.  But since I didn't want to change semantics
in this patch, I left it alone, and just updated the caller to use the
new flag semantics.

ec54d7d6e4 igb: prevent skb_over panic w/ mtu smaller than 1K
A panic has been observed with frame sizes smaller than 1K.  This has been
root caused to the hardware spanning larger frames across multiple buffers
and then reporting the original frame size in the first descriptor.  To
prevent this we can enable set the LPE bit which in turn will restrict
packet sizes to those set in the RLPML register.

1974cc205e sfc: Replace stats_enabled flag with a disable count
Currently we use a spin-lock to serialise statistics fetches and also
to inhibit them for short periods of time, plus a flag to
enable/disable statistics fetches for longer periods of time, during
online reset.  This was apparently insufficient to deal with the several
reasons for stats being disabled.

All 10Xpress PHYs require autonegotiation all the time; enforce this

Remove claimed support for 100M HD mode since it is not supported by

Do not set speed override bits when AN is enabled, and do not use
register 1.49192 for AN configuration as it can override what we set
elsewhere.

Always set the AN selector bits to 1 (802.3).

2d18835d65 sfc: SFX7101: Remove workaround for bad link training
Early versions of the SFX7101 firmware could complete link training in
a state where it would not adequately cancel noise (Solarflare bug
10750).  We previously worked around this by resetting the PHY after
seeing many Ethernet CRC errors.  This workaround is unsafe since it
takes no account of the interval between errors; it also appears to
be unnecessary with production firmware.  Therefore remove it.

e5664bb2a7 gianfar: Fix Wake-on-LAN support
commit 0f0ca340e5 ("phy: power
management support") caused a regression in the gianfar driver.

Now phylib turns off PHY power during suspend, and thus WOL
doesn't work anymore.

This patch workarounds the issue by enabling wakeup in the MDIO
device, i.e. just restores the old behaviour for the gianfar
driver. Note that this way all PHYs on a given MDIO bus won't
be turned off during suspend, which isn't good from the power
saving point of view.

A proper, per netdevice wakeup management support will need
a bit reworked phylib suspend/resume logic.

smsc9420 performs an interrupt signalling test when the interface is

This patch changes the code to set the test flag BEFORE enabling
interrupts. I've also removed an smp_wmb because the following spinlock

1af7ad5104 wimax: fix build issue when debugfs is disabled
As reported by Toralf Förster and Randy Dunlap.

- http://linuxwimax.org/pipermail/wimax/2009-January/000460.html

- http://lkml.org/lkml/2009/1/29/279

The definitions needed for the wimax stack and i2400m driver debug
infrastructure was, by mistake, compiled depending on CONFIG_DEBUG_FS
(by them being placed in the debugfs.c files); thus the build broke in
2.6.29-rc3 when debugging was enabled (CONFIG_WIMAX_DEBUG) and
DEBUG_FS was disabled.

These definitions are always needed if debug is enabled at compile
time (independently of DEBUG_FS being or not enabled), so moving them
to a file that is always compiled fixes the issue.

so restore it back to 1024.

This was reduced in commit 32ec803348
("netxen: reduce memory footprint").

Raising jumbo ring size from 512 to 1024, adds ~4MB per port, but
there's still big saving because of original patch (~20MB per port).

060210f938 b43: Dynamically control log verbosity
Dynamically control the log verbosity with a module parameter.
This enables us to dynamically enable debugging messages (or disable
info, warn, error messages) via module parameter or /sys/module/b43/parameters/verbose.

This increases the module size by about 3k. But in practice it reduces the
module size for the user, because some distributions ship the b43 module
with CONFIG_B43_DEBUG set, which increases the module by about 15k.

So with this patch applied, distributions should really _disable_ CONFIG_B43_DEBUG.
There is no reason to keep it in a production-release kernel.
So we have a net reduction in size by about 12k.

This patch also adds a printk of the wireless core revision, so people
don't have to enable SSB debugging to get the wireless core revision.

3) If both open and proprietary are available, it will work, because it selects

Current code for the RTL8187 is not returning valid retry information, thus the

is only obtained by reading a register, which cannot be read while in interrupt
context.

This patch implements the TX status return to mac80211 through the use of a
work queue.

One additional problem is that the driver currently enables the rate fallback
mechanism of the device, which conflicts with the mac80211 rate-setting
algorithm. This version of the patch disables rate fallback.

1fac36ee7d libertas: fix CF firmware loading for some cards
if_cs_poll_while_fw_download() returned the number of iterations
remaining on success, which in turn got returned as the value from
if_cs_prog_real() and if_cs_prog_helper().  But since if_cs_probe()
interprets non-zero return values from firmware load functions as an
error, this sometimes caused spurious firmware load failures.

0712612741 rt2x00: Simplify suspend/resume handling
With mac80211 handling all open interfaces during
suspend and resume we can simplify suspend/resume
within rt2x00lib.

The only thing rt2x00 needs to do is free up memory
during suspend and bring back the minimal required
components during resume.

5f8e077c0a ath9k: simplify regulatory code
Now that cfg80211 has its own regulatory infrastructure we can
condense ath9k's regulatory code considerably. We only keep data
we need to provide our own regulatory_hint(), reg_notifier() and
information necessary for calibration.

Atheros hardware supports 12 world regulatory domains, since these
are custom we apply them through the the new wiphy_apply_custom_regulatory().
Although we have 12 we can consolidate these into 5 structures based on
frequency and apply a different set of flags that differentiate them on
a case by case basis through the reg_notifier().

If CRDA is not found our own custom world regulatory domain is applied,
this is identical to cfg80211's except we enable passive scan on most
frequencies.

The ath5k driver didn't use set_rts_threshold or use_cts_prot, and also
didn't check the IEEE80211_TX_RC_USE_{RTS_CTS,CTS_PROTECT} RC flags.
Tell the hardware about these so RTS/CTS will work, and so the device
will work better in mixed b/g environments.

e9414b6b3f iwl3945: fix deep sleep when removing the driver.
A warning message "MAC is in deep sleep" sometimes happen when user removes
the driver.  This warning is related to card not being ready. In __iwl3945_down
function some of the going down steps are in wrong order, to fix this this patch
do the following:
	1- make sure we are calling iwl3945_apm_reset and iwl3945_apm_stop
	   in the right order.

	2- make sure we set CSR_GP_CNTRL_REG_FLAG_INIT_DONE in apm_reset before
	   poll on CSR_GP_CNTRL_REG_FLAG_MAC_CLOCK_READY.

	3- set correct polling counter.
