commit 93b6bd26b74efe46b4579592560f9f1cb7b61994 upstream.
We've had many reports of rt61pci failures with powersaving enabled.
Therefore, as a stop-gap measure, disable powersaving of the rt61pci
until we have found a proper solution.
Also disable powersaving on rt2800pci as it most probably will show
the same problem.

commit 56b34b91e22313294154cee0c16e294cf8a45b61 upstream.
Currently, the module does not initialize fully when the DIMMs aren't
ECC but remains still loaded. Propagate the error when no instance of
the driver is properly initialized and prevent further loading.
Reorganize and polish error handling in amd64_edac_init() while at it.

commit 505422517d3f126bb939439e9d15dece94e11d2c upstream.
The current rd/wrmsr_on_cpus helpers assume that the supplied
cpumasks are contiguous. However, there are machines out there
like some K8 multinode Opterons which have a non-contiguous core
enumeration on each node (e.g. cores 0,2 on node 0 instead of 0,1), see
http://www.gossamer-threads.com/lists/linux/kernel/1160268.
This patch fixes out-of-bounds writes (see URL above) by adding per-CPU
msr structs which are used on the respective cores.
Additionally, two helpers, msrs_{alloc,free}, are provided for use by
the callers of the MSR accessors.

commit c6e1971139be1342902873181f3b80a979bfb33b upstream.
The logic of is_disconnected_device/exists_disconnected_device is wrong
in that they are used to test whether a device is trying to connect (i.e.
connecting). For this reason the patch fixes them to not consider a
Closing or Closed device to be connecting. At the same time the patch
also renames the functions according to what they really do; you could
say a closed device is "disconnected" (the old name), but not "connecting"
(the new name).
This patch is a backport of changeset 909 from the Xenbits tree.

commit 22825ab7693fd29769518a0d25ba43c01a50092a upstream.
When a DASD device is used with the DIAG discipline, the DIAG
initialization will indicate success or error with a respective
return code. So far we have interpreted a return code of 4 as error,
but it actually means that the initialization was successful, but
the device is read-only. To allow read-only devices to be used with
DIAG we need to accept a return code of 4 as success.
Re-initialization of the DIAG access is also part of the DIAG error
recovery. If we find that the access mode of a device has been
changed from writable to read-only while the device was in use,
we print an error message.

commit b16d9acbdb97452d1418420e069acf7381ef10bb upstream.
Sometimes we will use a crtc for integerated LVDS, which is different with
that assigned by BIOS. If we want to get flicker-free transitions,
then we could read out the current state for it and set our current state
accordingly.
But it is true that if we aren't reading current state out, we do need
to turn everything off before modesetting. Otherwise the clocks can get very
angry and we get things worse than a flicker at boot.
In fact we also do the similar thing in UMS mode. We will disable all the
possible outputs/crtcs for the first modesetting.
So we disable all the possible outputs/crtcs before entering the KMS mode.
Before we configure connector/encoder/crtc, the function of
drm_helper_disable_unused_function can disable all the possible outputs/crtcs.

In 2.6.32.2 r600 had no IRQ support, however the patch in
500b758725314ab1b5316eb0caa5b0fa26740e6b to fix vblanks on avivo
cards, needs irqs.
So check for an R600 card and avoid this path if so.
This is a stable only patch for 2.6.32.2 as 2.6.33 has IRQs for r600.

commit c2ff581acab16c6af56d9e8c1a579bf041ec00b1 upstream.
The routine b43_is_hw_radio_enabled() has long been a problem.
For PPC architecture with PHY Revision < 3, a read of the register
B43_MMIO_HWENABLED_LO will cause a CPU fault unless b43_status()
returns a value of 2 (B43_STAT_STARTED) (BUG 14181). Fixing that
results in Bug 14538 in which the driver is unable to reassociate
after resuming from hibernation because b43_status() returns 0.
The correct fix would be to determine why the status is 0; however,
I have not yet found why that happens. The correct value is found for
my device, which has PHY revision >= 3.
Returning TRUE when the PHY revision < 3 and b43_status() returns 0 fixes
the regression for 2.6.32.
This patch fixes the problem in Red Hat Bugzilla #538523.

commit 70abc8cb90e679d8519721e2761d8366a18212a6 upstream.
Alan Stern noticed that e100 caused slab corruption.
commit 98468efddb101f8a29af974101c17ba513b07be1 changed
the allocation of cbs to use dma pools that don't return zeroed memory,
especially the cb->status field used to track which cb to clean, causing
(the visible) double freeing of skbs and a wrong free cbs count.
Now the cbs are explicitly zeroed at allocation time.

commit b7bb1756cb6a610cdbac8cfdad9e79bb5670b63b upstream.
I've also for a long time had a problem with the
temperature calculation code, which I had fixed
by byte-swapping the values, and now it turns out
that was the correct fix after all.
Also, any use of iwl_eeprom_query_addr() that is
for more than a u8 must be cast to little endian,
and some structs as well.
Fix all this. Again, no real impact on platforms
that already are little endian.

commit af6b8ee38833b39f70946f767740565ceb126961 upstream.
The construct "le16_to_cpu((__force __le16)(r >> 16))" has
always bothered me when looking through the iwlwifi code,
it shouldn't be necessary to __force anything, and before
this code, "r" was obtained with an ioread32, which swaps
each of the two u16 values in it properly when swapping the
entire u32 value. I've had arguments about this code with
people before, but always conceded they were right because
removing it only made things not work at all on big endian
platforms.
However, analysing a failure of the OTP reading code, I now
finally figured out what is going on, and why my intuition
about that code being wrong was right all along.
It turns out that the 'priv->eeprom' u8 array really wants
to have the data in it in little endian. So the force code
above and all really converts *to* little endian, not from
it. Cf., for instance, the function iwl_eeprom_query16() --
it reads two u8 values and combines them into a u16, in a
little-endian way. And considering it more, it makes sense
to have the eeprom array as on the device, after all not
all values really are 16-bit values, the MAC address for
instance is not.
Now, what this really means is that all the annotations are
completely wrong. The eeprom reading code should fill the
priv->eeprom array as a __le16 array, with __le16 values.
This also means that iwl_read_otp_word() should really have
a __le16 pointer as the data argument, since it should be
filling that in a format suitable for priv->eeprom.
Propagating these changes throughout, iwl_find_otp_image()
is found to be, now obviously visible, defective -- it uses
the data returned by iwl_read_otp_word() directly as if it
was CPU endianness. Fixing that, which is this hunk of the
patch:
- next_link_addr = link_value * sizeof(u16);
+ next_link_addr = le16_to_cpu(link_value) * sizeof(u16);
is the only real change of this patch. Everything else is
just fixing the sparse annotations.
Also, the bug only shows up on big endian platforms with a
1000 series card. 5000 and previous series do not use OTP,
and 6000 series has shadow RAM support which means we don't
ever use the defective code on any cards but 1000.

commit bc45a67079c916a9bd0a95b0b879cc0f259bac6e upstream.
we see from http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2125
that power saving does not work well on 3945. Since then power saving has
also been connected with association problems where an AP deathenticates a
3945 after it is unable to transmit data to it - this happens when 3945
enters power savings mode.
Disable power save support until issues are resolved.

debruijn32 (0x077CB531) is used to index gen_timer_index[]
which is an array of 32 u32. Having debruijn32 as unsigned

AMDPDU actions poke hardware for TX operation, as such
we want to turn hardware on for these actions. AMDPU RX operations
do not require hardware on as nothing is done in hardware for

My previous change added in:
commit 815833e7ecf0b9a017315cae6aef4d7cd9517681
ath9k: fix tx status reporting
was not checking all possible tx error conditions. This could possibly
lead to throughput issues due to slow rate control adaption or missed
retransmissions of failed A-MPDU frames.
This patch adds a mask for all possible error conditions and uses it
in the xmit ok check.

commit 242ab7ad689accafd5e87ffd22b85cf1bf7fbbef upstream.
The calibration period is now invoked by triggering a software
interrupt from within the ISR by ath5k_hw_calibration_poll()
instead of via a timer.
However, the calibration interval isn't initialized before
interrupts are enabled, so we can have a situation where an
interrupt occurs before the interval is assigned, so the
interval is actually negative. As a result, the ISR will
arm a software interrupt to schedule the tasklet, and then
rearm it when the SWI is processed, and so on, leading to a
softlockup at modprobe time.
Move the initialization order around so the calibration interval
is set before interrupts are active. Another possible fix
is to schedule the tasklet directly from the poll routine,
but I think there are additional plans for the SWI.

commit 45b241689179a6065384260242637cf21dabfb2d upstream.
The libertas driver copies the SSID buffer back to the wireless core and
appends a trailing NULL character for termination. This is
a) unnecessary because the buffer is allocated with kzalloc and is hence
already NULLed when this function is called, and
b) for priv->curbssparams.ssid_len == 32, it writes back one byte too
much which causes memory corruptions.
Fix this by removing the extra write.

commit cd78809f6191485a90ea6c92c2b58900ab5c156f upstream.
When continuing a pq calculation the driver needs 3 extra sources. The
driver can perform a 3 source calculation with a single descriptor, but
needs an extended descriptor to process up to 8 sources in one
operation. However, in the p-disabled case only one extra source is
needed. When continuing a p-disabled operation there are occasions
(i.e. 0 < src_cnt % 8 < 3) where the tail operation does not need an
extended descriptor. Properly account for this fact otherwise invalid
'dmacount' values will be written to hardware usually causing the
channel to halt with 'invalid descriptor' errors.

commit cbd1998377504df005302ac90d49db72a48552a6 upstream.
evms configures md arrays by:
open device
send ioctl
close device
for each different ioctl needed.
Since 2.6.29, the device can disappear after the 'close'
unless a significant configuration has happened to the device.
The change made by "SET_ARRAY_INFO" can too minor to stop the device
from disappearing, but important enough that losing the change is bad.
So: make sure SET_ARRAY_INFO sets mddev->ctime, and keep the device
active as long as ctime is non-zero (it gets zeroed with lots of other
things when the array is stopped).
This is suitable for -stable kernels since 2.6.29.

commit da307123c621b01cce147a4be313d8a754674f63 upstream.
This patch (as1315) fixes some bugs in the USB core authorization
code:
usb_deauthorize_device() should deallocate the device strings
instead of leaking them, and it should invoke
usb_destroy_configuration() (which does proper reference
counting) instead of freeing the config information directly.
usb_authorize_device() shouldn't change the device strings
until it knows that the authorization will succeed, and it should
autosuspend the device at the end (having autoresumed the
device at the start).
Because the device strings can be changed, the sysfs routines
to display the strings must protect the string pointers by
locking the device.

brightness status is reported by the Apple Cinema Displays as an
'unsigned char' (u8) value, but the code used 'char' instead.
Note that he driver was developed on the PowerPC architecture,
where the two types are synonymous, which is not always the case.
Fixed that. Otherwise the driver will interpret brightness
levels > 127 as negative, and fail to load.

commit ac06c06770bb8761b1f1f9bdf2f5420fa6d3e9fa upstream.
While converting emi62 to use request_firmware(), the driver was also
changed to use the ihex helper functions. However, this broke the loading
of the FPGA firmware because the code tries to access the addr field of
the EOF record which works with a plain array that has an empty last
record but not with the ihex helper functions where the end of the data is
signaled with a NULL record pointer, resulting in:
BUG: unable to handle kernel NULL pointer dereference at (null)
IP: [<f80d248c>] emi62_load_firmware+0x33c/0x740 [emi62]
This can be fixed by changing the loop condition to test the return value
of ihex_next_binrec() directly (like in emi26.c).

commit 13c199c0d0cf78b27592991129fb8cbcfc5164de upstream.
On some laptops it will return NOTIFY_OK(non-zero) when calling the ACPI LID
notifier. Then it is used as the result of ACPI LID resume function, which
will complain the following warning message in course of suspend/resume:
>PM: Device PNP0C0D:00 failed to resume: error 1
This patch is to eliminate the above warning message.

commit bdc731bc5fcd1794e9ac8ac80c389d302381c123 upstream.
BugLink: https://bugs.launchpad.net/ubuntu/+bug/435958
The module alias currently matches any Acer computer but when loaded the
BIOS checks will only succeed on Aspire One models. This causes a invalid
BIOS warning for all other models (seen on Aspire 4810T). This is not
fatal but worries users that see this message. Limiting the moule alias
to models starting with AOA or DOA for Packard Bell.
