As noticed by Alan Stern, there is still one issue with the driver:
we disable PCI IRQ on suspend, but other devices on the same IRQ
line might still need the IRQ enabled to suspend properly.
Nowadays, PCI core handles all power management work by itself, with
one condition though: if we use dev_pm_ops. So, rework the driver to
only quiesce 3c59x internal logic on suspend, while PCI core will
manage PCI device power state with IRQs disabled.

ATR support for UDP on 82599 needs to be redesigned, since the

We disable relaxed ordering of the descriptor writebacks for Tx head

David Howells noticed (due to the compiler warning about an unused
'pty_ops_bsd' variable) that we haven't actually been using the code
that implements TIOCSPTLCK for legacy pty handling. It's been that way
since 2.6.26, commit 3e8e88ca05 to be
exact ("pty: prepare for tty->ops changes").
DavidH initially submitted a patch just removing the dead code entirely,
and since nobody has apparently ever complained, I'm not entirely sure
that wouldn't be the right thing to do. But since the whole and only
point of the legacy pty code is to be compatible with legacy distros
that don't use the new unix98 pty model, let's just wire it up again.
And clean it up a bit while we're at it.

Since 2.6.29 the PCI PM core have been restoring the standard
configuration registers of PCI devices in the early phase of
resume. In particular, PCI devices without drivers have been handled
this way since commit 355a72d75b
(PCI: Rework default handling of suspend and resume). Unfortunately,
this leads to post-resume problems with CardBus devices which cannot
be accessed in the early phase of resume, because the sockets they
are on have not been woken up yet at that point.
To solve this problem, move the yenta socket resume to the early
phase of resume and, analogously, move the suspend of it to the late
phase of suspend. Additionally, remove some unnecessary PCI code
from the yenta socket's resume routine.
Fixes http://bugzilla.kernel.org/show_bug.cgi?id=13092, which is a
post-2.6.28 regression.

When hardware or uCode problem occurs driver captures significant
information from device to enable debugging. The format of this information
is different between 3945 and 4965 and later devices, yet currently the
3945 uses the 4965 and later format. Fix this by adding a new library call
that is initialized to the correct formatting routine based on device.
This moves the iwlagn event and error log handling back to iwl-agn.c to
make it part of iwlagn module.
Also remove the 3945 sysfs file that triggers dump of event log - there is
already a debugfs file that can do it for all drivers.

We keep track of where to write into a buffer by keeping a count of how
much has been written so far. When writing to the buffer we thus take the
buffer pointer and adding the count of what has been written so far.
Keeping track of what has been written so far is done by incrementing
this number every time something is written to the buffer with how much has
been written at that time.
Currently this number is incremented incorrectly when using the
"hex_dump_to_buffer" call to add data to the buffer. Fix this by only
adding what has been added to the buffer in that call instead of what has
been added since beginning of buffer.
Issue was discovered and discussed during testing of
https://bugzilla.redhat.com/show_bug.cgi?id=464598 .

The SPIC irq is not really shareable, the IO port cannot be cleared and
always returns some data so there is no real way to understand if the irq
is for us or not. Moreover the _PRS acpi method says the irq is not
shareable.
In addition to this, in some cases, an additional write to the IO port has
to be performed in order to properly decode the event received from the
device. This generates another interrupt which may overlap with the
previous one. In the future this is going to be important for properly
decoding events.

The following commit made console open fails while booting:
commit b50989dc44
Author: Alan Cox <alan@linux.intel.com>
Date: Sat Sep 19 13:13:22 2009 -0700
tty: make the kref destructor occur asynchronously
Due to tty release routines run in a workqueue now, error like the
following will be reported while booting:
INIT open /dev/console Input/output error
It also causes hibernation regression to appear as reported at
http://bugzilla.kernel.org/show_bug.cgi?id=14229
The reason is that now there's latency issue with closing, but when
we open a "closing not finished" tty, -EIO will be returned.
Fix it as per the following Alan's suggestion:
Fun but it's actually not a bug and the fix is wrong in itself as
the port may be closing but not yet being destructed, in which case
it seems to do the wrong thing. Opening a tty that is closing (and
could be closing for long periods) is supposed to return -EIO.
I suspect a better way to deal with this and keep the old console
timing is to split tty->shutdown into two functions.
tty->shutdown() - called synchronously just before we dump the tty
onto the waitqueue for destruction
tty->cleanup() - called when the destructor runs.
We would then do the shutdown part which can occur in IRQ context
fine, before queueing the rest of the release (from tty->magic = 0
... the end) to occur asynchronously
The USB update in -next would then need a call like
if (tty->cleanup)
tty->cleanup(tty);
at the top of the async function and the USB shutdown to be split
between shutdown and cleanup as the USB resource cleanup and final
tidy cannot occur synchronously as it needs to sleep.
In other words the logic becomes
final kref put
make object unfindable
async
clean it up

The message "ACPI: Device needs an ACPI driver" is misleading. The
device _may_ need an ACPI driver, if the BIOS implemented a custom
API for the device in question (which, AFAIK, can't be checked.) If
not, then either a generic ACPI driver may be used (for example
"thermal"), or nothing can be done (other than a white list).
I propose to reword the message to:
ACPI: If an ACPI driver is available for this device, you should use
it instead of the native driver
which I think is more correct. Comments and suggestions welcome.
I also added a message warning about possible problems and system
instability when users pass acpi_enforce_resources=lax, as suggested
by Len.

This makes sure every acpi_device has at least one ID. If we build an
acpi_device for a namespace node with no _HID or _CID, we sometimes
synthesize an ID like "LNXCPU" or "LNXVIDEO". If we don't even have
that, give it a default "device" ID.
Note that this means things like:
/sys/devices/LNXSYSTM:00/LNXSYBUS:00/HWP0001:00/HWP0002:04/device:00
(a PCI slot SxFy device) will have "hid" and "modprobe" entries, where
they didn't before. These aren't very useful (a HID of "device" doesn't
tell you what *kind* of device it is, so it doesn't help find a driver),

it to use acpi_walk_namespace() instead.
Besides removing some complicated code, this means we take advantage of the
namespace locking done by acpi_walk_namespace(). The locking isn't so
important at boot-time, but I hope to eventually use this same path to
handle hot-addition of devices, when it will be important.

This will also help remove the special case for adding the root node. We
currently add the root by hand before acpi_bus_scan(), but using a handle
here means we can start the acpi_bus_scan() directly with the root even
though it doesn't have an acpi_device yet.
Note that acpi_bus_scan() currently adds and/or starts the *children* of
its device argument. It doesn't do anything with the device itself.

[note this requires an fb patch posted to linux-fbdev-devel already]
This uses the normal video= command line option to control the kms
output setup at boot time. It is used to override the autodetection
done by kms.
video= normally takes a framebuffer as the first parameter, in kms
it will take a connector name, DVI-I-1, or LVDS-1 etc. If no output
connector is specified the mode string will apply to all connectors.
The mode specification used will match down the probed modes, and if
no mode is found it will add a CVT mode that matches.
video=1024x768 - all connectors match a 1024x768 mode or add a CVT on
video=VGA-1:1024x768, VGA-1 connector gets mode only.
The same strings as used in current fb modedb.c are used, except I've
added three more letters, e, D, d, e = enable, D = enable Digital,
d = disable, which allow a connector to be forced into a certain state.

This avoids needing to do a kmalloc > PAGE_SIZE for the main
indirect buffer chunk, it adds an accessor for all reads from
the chunk and caches a single page at a time for subsequent
reads.
changes since v1:
Use a two page pool which should be the most common case
a single packet spanning > PAGE_SIZE will be hit, but I'm
having trouble seeing anywhere we currently generate anything like that.
hopefully proper short page copying at end
added parser_error flag to set deep errors instead of having to test
every ib value fetch.

This is because the driver manages interrupts without checking for
netif_running().
Though, there are few other issues with suspend/resume in this driver.
The intention of calling free_irq() in suspend() was to avoid any
possible spurious interrupts (see commit 5b039e681b
"3c59x PM fixes"). But,
- On resume, the driver was requesting IRQ just after pci_set_master(),
but before vortex_up() (which actually resets 3c59x chips).
- Issuing free_irq() on a shared IRQ doesn't guarantee that a buggy
HW won't trigger spurious interrupts in another driver that
requested the same interrupt. So, if we want to protect from
unexpected interrupts, then on suspend we should issue disable_irq(),
not free_irq().

corresponding PCI BAR.

Multicast joins can succeed even if the IB port is down. This happens
when the SM runs on the same port with the requesting port. However,
IPoIB calls netif_carrier_on() when the join of the broadcast group
succeeds, without caring about the state of the IB port. The result
is an IPoIB interface in RUNNING state but without an active IB port
to support it.
If a bonding interface uses this IPoIB interface as a slave it might
not detect that this slave is almost useless and failover
functionality will be damaged. The fix checks the state of the IB
port in the carrier_task before calling netif_carrier_on().

Add support for the Freescale MPC83xx memory controller to the existing

between the two processors are in the CS_BNDS register parsing code, which
has been changed so it will work on both processors.
The L2 cache controller does not exist on the MPC83xx, but the OF
subsystem will not use the driver if the device is not present in the OF
device tree.
I had to change the nr_pages calculation to make the math work out. I
checked it on my board and did the math by hand for a 64GB 85xx using 64K

The periodic interrupt from drivers/char/hpet.c does not work correctly,
both when using the periodic capability of the hardware and while
emulating the periodic interrupt (when hardware does not support periodic
mode).
With timers capable of periodic interrupts, the comparator field is first
set with the period value followed by set of hidden accumulator, which has
the side effect of overwriting the comparator value. This results in
wrong periodicity for the interrupts. For, periodic interrupts to work,
following steps are necessary, in that order.
* Set config with Tn_VAL_SET_CNF bit
* Write to hidden accumulator, the value written is the time when the
first interrupt should be generated
* Write compartor with period interval for subsequent interrupts
(http://www.intel.com/hardwaredesign/hpetspec_1.pdf )
When emulating periodic timer with timers not capable of periodic
interrupt, driver is adding the period to counter value instead of
comparator value, which causes slow drift when using this emulation.
Also, driver seems to add hpetp->hp_delta both while setting up periodic
interrupt and while emulating periodic interrupts with timers not capable
of doing periodic interrupts. This hp_delta will result in slower than
expected interrupt rate and should not be used while setting the interval.

It happens because the new INPUT_WINBOND_CIR driver relies on new-leds
infrastructure - but does not select it in drivers/input/misc/Kconfig.
But it selects LEDS_CLASS, which confuses a number of other drivers into
thinking that all the leds infrastructure is in place.
Fix this by selecting NEW_LEDS as well, like similar drivers do.
Eventually, this whole leds infrastructure complexity should be
cleaned up, it's been going on for years.

Rename the locking free hvc_resize() function to __hvc_resize() and
provide an inline function that locks the hvc_struct and calls
__hvc_resize().
The rationale for this patch is that virtio_console calls the hvc_resize()
function without locking the hvc_struct. So it needs to call the lock
itself.
According to naming rules, the unlocked version is renamed and
prefixed with "__".
References to unlocked function calls in hvc back-ends has been updated.

Now we can tell the theoretical capacity remaining in the output
queue, virtio_net can waste entries by stopping the queue early.
It doesn't work in the case of indirect buffers and kmalloc failure,
but that's rare (we could drop the packet in that case, but other
drivers return TX_BUSY for similar reasons).
For the record, I think this patch reflects poorly on the linux
network API.

We put the virtio_net_hdr into the skb's cb region; turn this into a

The virtio_net driver is complicated by the two methods of freeing old
xmit buffers (in addition to freeing old ones at the start of the xmit
path).
The original code used a 1/10 second timer attached to xmit_free(),
reset on every xmit. Before we orphaned skbs on xmit, the
transmitting userspace could block with a full socket until the timer
fired, the skb destructor was called, and they were re-woken.
So we added the VIRTIO_F_NOTIFY_ON_EMPTY feature: supporting devices
send an interrupt (even if normally suppressed) on an empty xmit ring
which makes us schedule xmit_tasklet(). This was a benchmark win.
Unfortunately, VIRTIO_F_NOTIFY_ON_EMPTY makes quite a lot of work: a
host which is faster than the guest will fire the interrupt every xmit
packet (slowing the guest down further). Attempting mitigation in the
host adds overhead of userspace timers (possibly with the additional
pain of signals), and risks increasing latency anyway if you get it
wrong.
In practice, this effect was masked by benchmarks which take advantage
of GSO (with its inherent transmit batching), but it's still there.
Now we orphan xmitted skbs, the pressure is off: remove both paths and
no longer request VIRTIO_F_NOTIFY_ON_EMPTY. Note that the current
QEMU will notify us even if we don't negotiate this feature (legal,
but suboptimal); a patch is outstanding to improve that.
Move the skb_orphan/nf_reset to after we've done the send and notified
the other end, for a slight optimization.

This effectively reverts 99ffc696d1
"virtio: wean net driver off NETDEV_TX_BUSY".
The complexity of queuing an skb (setting a tasklet to re-xmit) is
questionable, especially once we get rid of the other reason for the
tasklet in the next patch.
If the skb won't fit in the tx queue, just return NETDEV_TX_BUSY.
This is frowned upon, so a followup patch uses a more complex solution.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Cc: Herbert Xu <herbert@gondor.apana.org.au>
The complex transmit free logic was introduced to avoid hangs on
removing the ip_conntrack module and also because drivers aren't
generally supposed to keep stale skbs for unbounded times.
After some debate, it was decided that while doing skb_orphan()
generally is a rat's nest, we can do it in this driver. Following
patches take advantage of this.

Holding agent->lock across cancel_delayed_work() (which does
del_timer_sync()) in ib_cancel_rmpp_recvs() leads to lockdep reports of
possible lock-timer deadlocks if a consumer ever does something that
connects agent->lock to a lock taken in IRQ context (cf
http://marc.info/?l=linux-rdma&m=125243699026045).
Fix this by changing the list items to a new state "CANCELING" while
holding the lock, and then canceling the delayed work without holding
the lock. If the delayed work runs after the lock is dropped, it will
see the state is CANCELING and return immediately, so the list will
stay stable while we traverse it with the lock not held.

would mean that the driver cannot report HW status
when the radio is re-enabled. Move this to ath_detach().
* Calling ath_radio_{enable/disable} without checking the current
state results in ath_radio_enable() being called repeatedly
for every invocation of rfkill_poll(). This is not needed
in any case since wiphy_rfkill_set_hw_state() would call

Replenishment of receive buffers is done in the tasklet handling
received frames as well as in a workqueue. When we are in the tasklet
we cannot sleep and thus attempt atomic skb allocations. It is generally
not a big problem if this fails since iwl_rx_allocate is always followed
by a call to iwl_rx_queue_restock which will queue the work to replenish
the buffers at a time when sleeping is allowed.
We thus add the __GFP_NOWARN to the skb allocation in iwl_rx_allocate to
reduce the noise if such an allocation fails while we still have enough
buffers. We do maintain the warning and the error message when we are low
on buffers to communicate to the user that there is a potential problem with
memory availability on system
This addresses issue reported upstream in thread "iwlagn: order 2 page
allocation failures" in
http://thread.gmane.org/gmane.linux.kernel.wireless.general/39187

commit 10c994ca70e8e94bbc85a5bf13de5911ee8de4d2 "iwlwifi: fix remove key
error" fixed an error reported by mac80211 during interface down. The fix
involved changing an async command to synchronous. Unfortunately this was
inside a spinlock section in which we cannot sleep.
Modify the sending of the command back to async. This causes the mac80211
error "mac80211-phy0: failed to remove key (0, ff:ff:ff:ff:ff:ff) from
hardware (-16)." to return. This error is not serious since this occurs
during interface down and the keys will be cleared anyway when ucode is
unloaded. Having this error message is thus less serious than a potential
deadlock introduced when sleeping while holding a spinlock. We will have to
find another fix for that error.
This is a revert of the abovementioned commit.

The current verison of b43 uses "b43_phyop_switch_analog_generic" for A,
G and LP phys.
According to the spec, this is the wrong behaviour for the LP PHY
(see: http://bcm-v4.sipsolutions.net/802.11/PHY/Anacore )
While no problems on the x86 plattform where seen, this leads to a crash
on the BCM5354 SoC (MIPS 32 LE plattform).

specs. It fixes the crash
