Alex Deucher cf4c12f9a2 drm/radeon/kms: fix tv module parameter
The tv parameter was added to disable the tv-out connector,
however, it caused a crash if it was set to 0 due to
drm_connector_init not getting called.  If tv=0, don't
attempt to add the connector.

Might fix:

Alex Deucher 0d9958b18e drm/radeon/kms: force legacy pll algo for RV515 LVDS
There has been periodic evidence that LVDS, on at least some
panels, prefers the dividers selected by the legacy pll algo.
This patch forces the use of the legacy pll algo on RV515
LVDS panels.  The old behavior (new pll algo) can be selected
by setting the new_pll module parameter to 1.

Alex Deucher 0b3b4fea0a drm/radeon/kms: remove useless clock code
This code was originally for forcing some clocks on certain asics.
However, this code was later moved to asic specific functions
for all of the affected asics.  The only users of the original
code at this point were r600, rv770, and evergreen and the code
was not relevant for those asics.  So, remove it.

Ben Hutchings 24cd804d1d 3c59x: Remove incorrect locking; correct documented lock hierarchy
vortex_ioctl() was grabbing vortex_private::lock around its call to
generic_mii_ioctl().  This is no longer necessary since there are more
specific locks which the mdio_{read,write}() functions will obtain.
Worse, those functions do not save and restore IRQ flags when locking
the MII state, so interrupts will be enabled when generic_mii_ioctl()
returns.

Since there is currently no need for any function to call
mdio_{read,write}() while holding another spinlock, do not change them
to save and restore IRQ flags but remove the specification of ordering
between vortex_private::lock and vortex_private::mii_lock.

stephen hemminger de6be6c1f7 sky2: don't do GRO on second port
There's something very important I forgot to tell you.
 What?

 Don't cross the GRO streams.
 Why?

 It would be bad.
 I'm fuzzy on the whole good/bad thing. What do you mean, "bad"?

 Try to imagine all the Internet as you know it stopping instantaneously
  and every bit in every packet swapping at the speed of light.
 Total packet reordering.
 Right. That's bad. Okay. All right. Important safety tip. Thanks, Hubert

The simplest way to stop this is just avoid doing GRO on the second port.
Very few Marvell boards support two ports per ring, and GRO is just
an optimization.

Dmitry Torokhov af045b8666 Input: i8042 - fix device removal on unload
We need to call platform_device_unregister(i8042_platform_device)
before calling platform_driver_unregister() because i8042_remove()
resets i8042_platform_device to NULL. This leaves the platform device
instance behind and prevents driver reload.

Luis R. Rodriguez 904879748d ath9k_hw: fix parsing of HT40 5 GHz CTLs
The 5 GHz CTL indexes were not being read for all hardware
devices due to the masking out through the CTL_MODE_M mask
being one bit too short. Without this the calibrated regulatory
maximum values were not being picked up when devices operate
on 5 GHz in HT40 mode. The final output power used for Atheros
devices is the minimum between the calibrated CTL values and
what CRDA provides.

Christian Lamparter f880c2050f p54: fix tx feedback status flag check
Michael reported that p54* never really entered power
save mode, even tough it was enabled.

It turned out that upon a power save mode change the
firmware will set a special flag onto the last outgoing
frame tx status (which in this case is almost always the
designated PSM nullfunc frame). This flag confused the
driver; It erroneously reported transmission failures
to the stack, which then generated the next nullfunc.
and so on...

NeilBrown 070dc6dd71 md: resolve confusion of MD_CHANGE_CLEAN
MD_CHANGE_CLEAN is used for two different purposes and this leads to
confusion.
One of the purposes is largely mirrored by MD_CHANGE_PENDING which is
not used for anything else, so have MD_CHANGE_PENDING take over that
purpose fully.

The two purposes are:
 1/ tell md_update_sb that an update is needed and that it is just a
   clean/dirty transition.
 2/ tell user-space that an transition from clean to dirty is pending
    (something wants to write), and tell te kernel (by clearin the
    flag) that the transition is OK.

The first purpose remains wit MD_CHANGE_CLEAN, the second is moved
fully to MD_CHANGE_PENDING.

This means that various places which conditionally set or cleared
MD_CHANGE_CLEAN no longer need to be conditional.

If this bit is cleared in md_update_sb() the kernel will allow writes to the
array if userspace triggers md_allow_write(), e.g. through stripe_cache_size,
when mdmon is not active.  When mdmon is active the array transitions to
active-idle bypassing write-pending, setting up a race for mdmon to set the
array clean before a write arrives.

Artem Bityutskiy 80c1c16fb8 UBI: fix forward compatibility
Commit 0798cea8c2 "UBI: improve corrupted flash handling"
broke delet-compatible volumes handling - it introduced a limit of 8 eraseblocks which
may be corrupted. And delete-compatible eraseblocks are added to the "corrupted" list,
so if we'd have a large delete-compatible volume, UBI would refuse it.

The fix is to add delete-compatible volumes to the erase list instead. Indeed, they are
corrupted, we just have to erase them.

Stefan Richter a4dc090b6c firewire: ohci: work around VIA and NEC PHY packet reception bug
VIA VT6306, VIA VT6308, and NEC OrangeLink controllers do not write
packet event codes for received PHY packets (or perhaps write
evt_no_status, hard to tell).  Work around it by overwriting the
packet's ACK by ack_complete, so that upper layers that listen to PHY
packet reception get to see these packets.

(Also tested:  TI TSB82AA2, TI TSB43AB22/A, TI XIO2213A, Agere FW643,
JMicron JMB381 --- these do not exhibit this bug.)

Clemens proposed a quirks flag for that, IOW whitelist known misbehaving
controllers for this workaround.  Though to me it seems harmless enough
to enable for all controllers.

The log_ar_at_event() debug log will continue to show the original
status from the DMA unit.

Arnd Bergmann 2c4e9671ed Input: use PIT_TICK_RATE in vt beep ioctl
The KIOCSOUND and KDMKTONE ioctls are based on the CLOCK_TICK_RATE,
which is architecture and sometimes configuration specific.

In practice, most user applications assume that it is actually defined
as the i8253 PIT base clock of 1193182 Hz, which is true on some
architectures but not on others.

This patch makes the vt code use the PIT frequency on all
architectures, which is much more well-defined.  It will change the
behavior of user applications sending the beep ioctl on all
architectures that define CLOCK_TICK_RATE different from
PIT_TICK_RATE.

The original breakage was introduced in commit bcc8ca099 "Adapt
drivers/char/vt_ioctl.c to non-x86".  Hopefully, reverting this change
will make the frequency correct in more cases than it will make it
incorrect.

patch introduced in the above commit changed the cast from (signed char)
to (signed).  When cast as a signed integer and negated, the value of -1
(stored in the byte as 0xff) became -255 rather than 1.  This patch
reverts the cast to a (signed char) and also removes an unnecessary
(signed) cast, as all the values operated on are bitmasked.

Mike Rapoport 557de5eb29 libertas: if_sdio: fix buffer alignment in struct if_sdio_card
The commit 886275ce41 (param: lock
if_sdio's lbs_helper_name and lbs_fw_name against sysfs changes)
introduced new fields into the if_sdio_card structure. It caused
missalignment of the if_sdio_card.buffer field and failure at driver
load time:

  ~# modprobe libertas_sdio

  [   62.319976] libertas_sdio: Copyright Pierre Ossman

  [   66.016296] libertas: PREP_CMD: command 0x0003 failed: -110

Adding explicit alignment attribute for the if_sdio_card.buffer field
fixes this problem.

Change the code to adjust the start and end for range restricted

Borislav Petkov 37b7370a8d amd64_edac: Do not report error overflow as a separate error
When the Overflow MCi_STATUS bit is set, EDAC reports the lost error
with a "no information available" message which often puzzles users
parsing the dmesg. This doesn't make much sense since this error has
been lost anyway so no need for reporting it separately. Thus, report
the overflow bit setting in the MCE dump instead. While at it, remove
reporting of MiscV and ErrorEnable (en) which are superfluous.

Now it looks like this:

Since the chips don't have proper BM DMA status,

Commit 8bf0223ed515be24de0c671eedaff49e78bebc9c (hwmon, k8temp: Fix
temperature reporting for ASB1 processor revisions) fixed temperature
reporting for ASB1 CPUs. But those CPU models (model 0x6b, 0x6f, 0x7f)
were packaged both as AM2 (desktop) and ASB1 (mobile). Thus the commit
leads to wrong temperature reporting for AM2 CPU parts.

The solution is to determine the package type for models 0x6b, 0x6f,
0x7f.

This is done using BrandId from CPUID Fn8000_0001_EBX[15:0]. See
"Constructing the processor Name String" in "Revision Guide for AMD
NPT Family 0Fh Processors" (Rev. 3.46).

Robert Richter 750d857c68 oprofile: fix crash when accessing freed task structs
This patch fixes a crash during shutdown reported below. The crash is
caused by accessing already freed task structs. The fix changes the
order for registering and unregistering notifier callbacks.

All notifiers must be initialized before buffers start working. To
stop buffer synchronization we cancel all workqueues, unregister the
notifier callback and then flush all buffers. After all of this we
finally can free all tasks listed.

This should avoid accessing freed tasks.

Anton Vorontsov ef24b16b5d phylib: Fix race between returning phydev and calling adjust_link
It is possible that phylib will call adjust_link before returning
from {,of_}phy_connect(), which may cause the following [very rare,
though] oops upon reopening the device:

  Unable to handle kernel paging request for data at address 0x0000024c
  Oops: Kernel access of bad area, sig: 11 [#1]

  [c0d25f30] [c036c158] phy_state_machine+0x3ac/0x554
  [...]

Here is why. Drivers store phydev in their private structures, e.g.
gianfar driver:

static int init_phy(struct net_device *dev)
{
	...
	priv->phydev = of_phy_connect(...);
	...
}

So that adjust_link could retrieve it back:

static void adjust_link(struct net_device *dev)
{
	...
	struct phy_device *phydev = priv->phydev;
	...
}

If the device has been opened before, then phydev->state is set to
PHY_HALTED (or undefined if the driver didn't call phy_stop()).

Now, phy_connect starts the PHY state machine before returning phydev to
the driver:

	phy_start_machine(phydev, NULL);

	if (phydev->irq > 0)
		phy_start_interrupts(phydev);

	return phydev;

The time between 'phy_start_machine()' and 'return phydev' is undefined.
The start machine routine delays execution for 1 second, which is enough
for most cases. But under heavy load, or if you're unlucky, it is quite
possible that PHY state machine will execute before phy_connect()
returns, and so adjust_link callback will try to dereference phydev,
which is not yet ready.

To fix the issue, simply initialize the PHY's state to PHY_READY during
phy_attach(). This will ensure that phylib won't call adjust_link before
phy_start().

In principle PCIe port services may be enabled by the BIOS, so it's

Rafael J. Wysocki 28eb5f274a PCI: PCIe: Ask BIOS for control of all native services at once
After commit 852972acff (ACPI: Disable
ASPM if the platform won't provide _OSC control for PCIe) control of
the PCIe Capability Structure is unconditionally requested by
acpi_pci_root_add(), which in principle may cause problems to
happen in two ways.  First, the BIOS may refuse to give control of
the PCIe Capability Structure if it is not asked for any of the
_OSC features depending on it at the same time.  Second, the BIOS may
assume that control of the _OSC features depending on the PCIe
Capability Structure will be requested in the future and may behave
incorrectly if that doesn't happen.  For this reason, control of
the PCIe Capability Structure should always be requested along with
control of any other _OSC features that may depend on it (ie. PCIe
native PME, PCIe native hot-plug, PCIe AER).

Rework the PCIe port driver so that (1) it checks which native PCIe
port services can be enabled, according to the BIOS, and (2) it
requests control of all these services simultaneously.  In
particular, this causes pcie_portdrv_probe() to fail if the BIOS
refuses to grant control of the PCIe Capability Structure, which
means that no native PCIe port services can be enabled for the PCIe
Root Complex the given port belongs to.  If that happens, ASPM is
disabled to avoid problems with mishandling it by the part of the
PCIe hierarchy for which control of the PCIe Capability Structure
has not been received.

Make it possible to override this behavior using 'pcie_ports=native'
(use the PCIe native services regardless of the BIOS response to the
control request), or 'pcie_ports=compat' (do not use the PCIe native
services at all).

Accordingly, rework the existing PCIe port service drivers so that
they don't request control of the services directly.

Rafael J. Wysocki 75fb60f26b ACPI/PCI: Negotiate _OSC control bits before requesting them
It is possible that the BIOS will not grant control of all _OSC
features requested via acpi_pci_osc_control_set(), so it is
recommended to negotiate the final set of _OSC features with the
query flag set before calling _OSC to request control of these
features.

To implement it, rework acpi_pci_osc_control_set() so that the caller
can specify the mask of _OSC control bits to negotiate and the mask
of _OSC control bits that are absolutely necessary to it.  Then,
acpi_pci_osc_control_set() will run _OSC queries in a loop until
the mask of _OSC control bits returned by the BIOS is equal to the
mask passed to it.  Also, before running the _OSC request
acpi_pci_osc_control_set() will check if the caller's required
control bits are present in the final mask.

Using this mechanism we will be able to avoid situations in which the
BIOS doesn't grant control of certain _OSC features, because they
depend on some other _OSC features that have not been requested.

Rafael J. Wysocki 2b8fd9186d ACPI/PCI: Do not preserve _OSC control bits returned by a query
There is the assumption in acpi_pci_osc_control_set() that it is
always sufficient to compare the mask of _OSC control bits to be
requested with the result of an _OSC query where all of the known
control bits have been checked.  However, in general, that need not
be the case.  For example, if an _OSC feature A depends on an _OSC
feature B and control of A, B plus another _OSC feature C is
requested simultaneously, the BIOS may return A, B, C, while it would
only return C if A and C were requested without B.

That may result in passing a wrong mask of _OSC control bits to an
_OSC control request, in which case the BIOS may only grant control
of a subset of the requested features.  Moreover, acpi_pci_run_osc()
will return error code if that happens and the caller of
acpi_pci_osc_control_set() will not know that it's been granted
control of some _OSC features.  Consequently, the system will
generally not work as expected.

Apart from this acpi_pci_osc_control_set() always uses the mask
of _OSC control bits returned by the very first invocation of
acpi_pci_query_osc(), but that is done with the second argument
equal to OSC_PCI_SEGMENT_GROUPS_SUPPORT which generally happens
to affect the returned _OSC control bits.

For these reasons, make acpi_pci_osc_control_set() always check if
control of the requested _OSC features will be granted before making
the final control request.  As a result, the osc_control_qry and
osc_queried members of struct acpi_pci_root are not necessary any
more, so drop them and remove the remaining code referring to them.

Jeremy Fitzhardinge dffe2e1e1a xen: handle events as edge-triggered
Xen events are logically edge triggered, as Xen only calls the event
upcall when an event is newly set, but not continuously as it remains set.
As a result, use handle_edge_irq rather than handle_level_irq.

This has the important side-effect of fixing a long-standing bug of
events getting lost if:
 - an event's interrupt handler is running
 - the event is migrated to a different vcpu
 - the event is re-triggered

The most noticable symptom of these lost events is occasional lockups
of blkfront.

Many thanks to Tom Kopec and Daniel Stodden in tracking this down.

 - use a specific percpu irq_chip implementation, and
 - handle them with handle_percpu_irq

This makes the path for delivering these interrupts more efficient

to migrate them.

Neil Horman aa25ab7d94 3c59x: Fix deadlock between boomerang_interrupt and boomerang_start_tx
If netconsole is in use, there is a possibility for deadlock in 3c59x between
boomerang_interrupt and boomerang_start_xmit.  Both routines take the vp->lock,
and if netconsole is in use, a pr_* call from the boomerang_interrupt routine
will result in the netconsole code attempting to trnasmit an skb, which can try
to take the same spin lock, resulting in deadlock.

The fix is pretty straightforward.  This patch allocats a bit in the 3c59x
private structure to indicate that its handling an interrupt.  If we get into
the transmit routine and that bit is set, we can be sure that we have recursed
and will deadlock if we continue, so instead we just return NETDEV_TX_BUSY, so
the stack requeues the skb to try again later.

The patch with title below makes reference count of usb serial module
always more than one after driver is bound.

	USB-BKL: Remove BKL use for usb serial driver probing

In fact, the patch above only replaces lock_kernel() with try_module_get()
, and does not use module_put() to do what unlock_kernel() did, so casue leak
of reference count of usb serial module and the module can not be unloaded
after serial driver is bound with device.

This patch fixes the issue, also simplifies such things:
	-only call try_module_get() once in the entry of usb_serial_probe()
	-only call module_put() once in the exit of usb_serial_probe

I recently bought a i-gotU USB GPS, and whilst hunting around for linux
support discovered this post by you back in 2009:

http://kerneltrap.org/mailarchive/linux-usb/2009/3/12/5148644

>Try the navman driver instead.  You can either add the device id to the

> 	echo -n "0x0df7 0x0900" > /sys/bus/usb-serial/drivers/navman/new_id
>
> and then plug your device in and see if that works.

I can confirm that the navman driver works with the right device IDs on
my i-gotU GT-600, which has the same device IDs.  Attached is a patch
adding the IDs.

Michael Hennerich ebb8a4e487 USB: isp1760: use a write barrier to ensure proper ndelay timing
The ISP1760 has some timing requirements where it has to delay a short
period after a write to a register has started.  However, this delay is
from the time the write hits the USB chip (the ISP1760), not from the
time where the processor started processing the write.  So on a quick
enough processor, it is sometimes possible for the write to not hit the
device before we start delaying, and we then violate the part's timing
requirements, so things stop working.

To avoid all this, insert a write barrier after the register write and
before the timing delay/register read so we can guarantee we only start
counting time after the write has hit the device.

Sven Eckelmann f86b998425 Staging: batman-adv: Don't write in not allocated packet_buff
Each net_device in a system will automatically managed as a possible
batman_if and holds different informations like a buffer with a prepared
originator messages. To reduce the memory usage, the packet_buff will
only be allocated when the interface is really added/enabled for
batman-adv.

The function to update the hw address information inside the packet_buff
just assumes that the packet_buff is always initialised and thus the
kernel will just oops when we try to change the hw address of a not
already fully enabled interface.

We must always check if the packet_buff is allocated before we try to
change information inside of it.

dev_put allows a device to be freed when all its references are dropped.
After that we are not allowed to access that information anymore. Access
to the data structure of a net_device must be surrounded a dev_hold
and ended using dev_put.

batman-adv adds a device to its own management structure in
hardif_add_interface and will release it in hardif_remove_interface.
Thus it must hold a reference all the time between those functions to
prevent any access to the already released net_device structure.

Johannes Berg f45f3c1f3f firmware_class: fix typo in error path
In the error path, _request_firmware sets
firmware_p to NULL rather than *firmware_p,
which leads to passing a freed firmware
struct to drivers when the firmware file
cannot be found. Fix this.

Broken by commit f8a4bd3456.

Jonathan Corbet c76a3e1d6c ACPI_TOSHIBA needs LEDS support
Don't ask how ACPI_TOSHIBA got enabled on in desktop system's .config -
I don't know.  But it has silently been there until I tried 2.6.36-rc2,
where it broke the build because I don't have LED support turned on.
Attached patch fixes things up.

(I had to change BACKLIGHT_CLASS_DEVICE to "depends" because otherwise
I get unsightly core dumps out of scripts/kconfig/conf).

Ian Campbell 1dc7ce99b0 xen: pvhvm: rename xen_emul_unplug=ignore to =unnnecessary
It is not immediately clear what this option causes to become
ignored. The actual meaning is that it is not necessary to unplug the
emulated devices to safely use the PV ones, even if the platform does
not support the unplug protocol. (pressumably the user will only add
this option if they have ensured that their domain configuration is
safe).

I think xen_emul_unplug=unnecessary better captures this.

Stephen M. Cameron 75230ff275 cciss: disable doorbell reset on reset_devices
The doorbell reset initially appears to work correctly,
the controller resets, comes up, some i/o can even be
done, but on at least some Smart Arrays in some servers,
it eventually causes a subsequent controller lockup due
to some kind of PCIe error, and kdump can end up leaving
the root filesystem in an unbootable state.  For this
reason, until the problem is fixed, or at least isolated
to certain hardware enough to be avoided, the doorbell
reset should not be used at all.

Chris Wilson 156dadc180 drm/i915: Remove the conflicting BUG_ON()
We now attempt to free "active" objects following a GPU hang as either
the GPU will be reset or the hang is permenant. In either case, the GPU
writes will not be flushed to main memory and it should be safe to
return that memory back to the system.

The BUG_ON(active) is thus overkill and can erroneously fire after a
EIO.

Jesse Barnes 9d0498a2bf drm/i915: wait for actual vblank, not just 20ms
Waiting for a hard coded 20ms isn't always enough to make sure a vblank
period has actually occurred, so add code to make sure we really have
passed through a vblank period (or that the pipe is off when disabling).

This prevents problems with mode setting and link training, and seems to
fix a bug like https://bugs.freedesktop.org/show_bug.cgi?id=29278, but
on an HP 8440p instead.  Hopefully also fixes

Bruce Allan 1aef70ef12 e1000e: don't check for alternate MAC addr on parts that don't support it
From: Bruce Allan <bruce.w.allan@intel.com>

The alternate MAC address feature is only supported by 80003ES2LAN and
82571 LOMs as well as a couple 82571 mezzanine cards.  Checking for an
alternate MAC address on other parts can fail leading to the driver not
able to load.  This patch limits the check for an alternate MAC address
to be done only for parts that support the feature.

This issue has been around since support for the feature was introduced
to the e1000e driver in 2.6.34.

Dan Carpenter 09f0c489fa drm: move dereference below check
"fb_helper_conn" is dereferenced before the check for NULL.  It's never
actually NULL here, so this is mostly to keep the static checkers happy.
