commit 653a39d1f61bdc9f277766736d21d2e9be0391cb upstream.
When there's an xHCI host power loss after a suspend from memory, the USB
core attempts to reset and verify the USB devices that are attached to the
system. The xHCI driver has to reallocate those devices, since the
hardware lost all knowledge of them during the power loss.
When a hub is plugged in, and the host loses power, the xHCI hardware
structures are not updated to say the device is a hub. This is usually
done in hub_configure() when the USB hub is detected. That function is
skipped during a reset and verify by the USB core, since the core restores
the old configuration and alternate settings, and the hub driver has no
idea this happened. This bug makes the xHCI host controller reject the
enumeration of low speed devices under the resumed hub.
Therefore, make the USB core re-setup the internal xHCI hub device
information by calling update_hub_device() when hub_activate() is called
for a hub reset resume. After a host power loss, all devices under the
roothub get a reset-resume or a disconnect.
This patch should be queued for the 2.6.37 stable tree.

dm: Call blk_abort_queue on failed paths
Multipath began to use blk_abort_queue() to allow for
lower latency path deactivation. This was found to
cause list corruption:
the cmd gets blk_abort_queued/timedout run on it and the scsi eh
somehow is able to complete and run scsi_queue_insert while
scsi_request_fn is still trying to process the request.

commit c217649bf2d60ac119afd71d938278cffd55962b upstream.
No longer needlessly hold md->bdev->bd_inode->i_mutex when changing the
size of a DM device. This additional locking is unnecessary because
i_size_write() is already protected by the existing critical section in
dm_swap_table(). DM already has a reference on md->bdev so the
associated bd_inode may be changed without lifetime concerns.
A negative side-effect of having held md->bdev->bd_inode->i_mutex was
that a concurrent DM device resize and flush (via fsync) would deadlock.
Dropping md->bdev->bd_inode->i_mutex eliminates this potential for
deadlock. The following reproducer no longer deadlocks:

commit 9b29050f8f75916f974a2d231ae5d3cd59792296 upstream.
The current TPM TIS driver in git discards the timeout values returned
from the TPM. The check of the response packet needs to consider that
the return_code field is 0 on success and the size of the expected
packet is equivalent to the header size + u32 length indicator for the
TPM_GetCapability() result + 3 timeout indicators of type u32.
I am also adding a sysfs entry 'timeouts' showing the timeouts that are
being used.

commit c4ff4b829ef9e6353c0b133b7adb564a68054979 upstream.
If duration variable value is 0 at this point, it's because
chip->vendor.duration wasn't filled by tpm_get_timeouts() yet.
This patch sets then the lowest timeout just to give enough
time for tpm_get_timeouts() to further succeed.
This fix avoids long boot times in case another entity attempts
to send commands to the TPM when the TPM isn't accessible.

commit bf572541ab44240163eaa2d486b06f306a31d45a upstream.
Commit 1a855a0606 (2.6.37-rc4) fixed a problem where devices were
re-added when they shouldn't be but caused a regression in a less
common case that means sometimes devices cannot be re-added when they
should be.
In particular, when re-adding a device to an array without metadata
we should always access the device, but after the above commit we
didn't.
This patch sets the In_sync flag in that case so that the re-add
succeeds.
This patch is suitable for any -stable kernel to which 1a855a0606 was
applied.

commit 4e5518ca53be29c1ec3c00089c97bef36bfed515 upstream.
pcmcia_request_irq() and pcmcia_enable_device() are intended
to be called from process context (first function allocate memory
with GFP_KERNEL, second take a mutex). We can not take spin lock
and call them.
It's safe to move spin lock after pcmcia_enable_device() as we
still hold off IRQ until dev->base_addr is 0 and driver will
not proceed with interrupts when is not ready.

commit 86af95039b69a90db15294eb1f9c147f1df0a8ea upstream.
A check against division by zero was modified in commit b0525b48.
Since this change time_to_empty_now is always reported as zero
while the battery is discharging and as a negative value while
the battery is charging. This is because current is negative while
the battery is discharging.
Fix the check introduced by commit b0525b48 so that time_to_empty_now
is reported correctly during discharge and as zero while charging.

directory, create each device under the corresponding
pci device node. Symlinks to all virtio-pci
devices can be found under the pci driver link in
bus/pci/drivers/virtio-pci/devices, and all virtio
devices under drivers/bus/virtio/devices.

commit 99a0fadf561e1f553c08f0a29f8b2578f55dd5f0 upstream.
pci-stub uses strsep() to separate list of ids and generates a warning
message when it fails to parse an id. However, not specifying the
parameter results in ids set to an empty string. strsep() happily
returns the empty string as the first token and thus triggers the
warning message spuriously.
Make the tokner ignore zero length ids.

commit 2fb08e6ca9f00d1aedb3964983e9c8f84b36b807 upstream.
rtc-cmos was setting suspend/resume hooks at the device_driver level.
However, the platform bus code (drivers/base/platform.c) only looks for
resume hooks at the dev_pm_ops level, or within the platform_driver.
Switch rtc_cmos to use dev_pm_ops so that suspend/resume code is executed
again.
Paul said:
: The user visible symptom in our (XO laptop) case was that rtcwake would
: fail to wake the laptop. The RTC alarm would expire, but the wakeup
: wasn't unmasked.

: As for severity, the impact may have been reduced because if I recall

commit 4224489f45b503f0a1f1cf310f76dc108f45689a upstream.
There was a configuration page timing out during the initial port
enable at driver load time. The port enable would fail, and this would
result in the driver unloading itself, meanwhile the driver was accessing
freed memory in another context resulting in the panic. The fix is to
prevent access to freed memory once the driver had issued the diag reset
which woke up the sleeping port enable process. The routine
_base_reset_handler was reorganized so the last sleeping process woken up was
the port_enable.

The ioc->hba_queue_depth is not properly resized when the controller
firmware reports that it supports more outstanding IO than what can be fit
inside the reply descriptor pool depth. This is reproduced by setting the
controller global credits larger than 30,000. The bug results in an
incorrect sizing of the queues. The fix is to resize the queue_size by
dividing queue_diff by two.

commit 4dc2757a2e9a9d1f2faee4fc6119276fc0061c16 upstream.
When zoning end devices, the driver is not sending device
removal handshake alogrithm to firmware. This results in controller
firmware not sending sas topology add events the next time the device is

even though the PHYSTATUS_VACANT bit is set in the PhyStatus of the
event data. The current design is avoiding the handshake when the
VACANT bit is set in the phy status.

commit a8733c7baf457b071528e385a0b7d4aaec79287c upstream.
Our current handling of medium error assumes that data is returned up
to the bad sector. This assumption holds good for all disk devices,
all DIF arrays and most ordinary arrays. However, an LSI array engine
was recently discovered which reports a medium error without returning
any data. This means that when we report good data up to the medium
error, we've reported junk originally in the buffer as good. Worse,
if the read consists of requested data plus a readahead, and the error
occurs in readahead, we'll just strip off the readahead and report
junk up to userspace as good data with no error.
The fix for this is to have the error position computation take into
account the amount of data returned by the driver using the scsi
residual data. Unfortunately, not every driver fills in this data,
but for those who don't, it's set to zero, which means we'll think a
full set of data was transferred and the behaviour will be identical
to the prior behaviour of the code (believe the buffer up to the error
sector). All modern drivers seem to set the residual, so that should
fix up the LSI failure/corruption case.

commit 554d1d027b19265c4aa3f718b3126d2b86e09a08 upstream.
Since commit 6cd0b1cb872b3bf9fc5de4536404206ab74bafdd "iwlagn: fix
hw-rfkill while the interface is down", we enable interrupts when
device is not ready to receive them. However hardware, when it is in
some inconsistent state, can generate other than rfkill interrupts
and crash the system. I can reproduce crash with "kernel BUG at
drivers/net/wireless/iwlwifi/iwl-agn.c:1010!" message, when forcing
firmware restarts.
To fix only enable rfkill interrupt when down device and after probe.
I checked patch on laptop with 5100 device, rfkill change is still
passed to user space when device is down.

commit 91a970d9889c7d6f451ee91ed361d0f0119d3778 upstream.
The device driver must allocate memory for IUCV buffers with GFP_DMA,
because IUCV cannot address memory above 2GB (31bit addresses only).
Because the IUCV ignores the higher bits of the address, sending and
receiving IUCV data with this driver might cause memory corruptions.

commit 7c161d0b900ea9bd9fc5ea5d3fa9916e9eb0dd88 upstream.
The hv_netvsc gets RNDIS_STATUS_MEDIA_CONNECT event after the VM
is live migrated. Adding call to netif_notify_peers() for this event
to send GARP (Gratuitous ARP) to notify network peers. Otherwise,
the VM's network connection may stop after a live migration.
This patch should also be applied to stable kernel 2.6.32 and later.

commit d1ce318496f5943d2cc5e20171fc383a59a1421f upstream.
The ni_labpc driver module only requests a shared IRQ for PCI devices,
requesting a non-shared IRQ for non-PCI devices.
As this module is also used by the ni_labpc_cs module for certain
National Instruments PCMCIA cards, it also needs to request a shared IRQ
for PCMCIA devices, otherwise you get a IRQ mismatch with the CardBus
controller.

If anyone comes across a high-speed hub that (by mistake or by design)
claims to have no Transaction Translators, plugging a full- or
low-speed device into it will cause the USB stack to crash. This
patch (as1446) prevents the problem by ignoring such devices, since
the kernel has no way to communicate with them.

commit 271c1150b4f8e1685e5a8cbf76e329ec894481da upstream.
The major and minor number saved in the product_info structure
were copied from the address instead of the data, causing an
inconsistency in the reported versions during firmware loading:
usb 4-1: firmware: requesting edgeport/down.fw
/usr/src/linux/drivers/usb/serial/io_edgeport.c: downloading firmware version (930) 1.16.4
[..]
/usr/src/linux/drivers/usb/serial/io_edgeport.c: edge_startup - time 3 4328191260
/usr/src/linux/drivers/usb/serial/io_edgeport.c: FirmwareMajorVersion 0.0.4

commit ad84e4a9efb7c8ed322bafb6ebdb9c3a49a3d3a8 upstream.
This patch (as1442) fixes a bug in g_printer: Module parameters should
not be marked "__initdata" if they are accessible in sysfs (i.e., if
the mode value in the module_param() macro is nonzero). Otherwise
attempts to access the parameters will cause addressing violations.
Character-string module parameters must not be marked "__initdata"
if the module can be unloaded, because the kernel needs to access the
parameter variable at unload time in order to free the
dynamically-allocated string.

commit f75593ceaa08e6d27aec1a5de31cded19e850dd1 upstream.
This patch (as1440) fixes a bug in ehci-hcd. ehci->periodic_size is
used to compute the size in a dma_alloc_coherent() call, but then it
gets changed later on. As a result, the corresponding call to
dma_free_coherent() passes a different size from the original
allocation. Fix the problem by adjusting ehci->periodic_size before
carrying out any of the memory allocations.
