A recent commit "mmc: sh_mmcif: fix clock management" has introduced a
use after free bug in sh_mmcif.c: in sh_mmcif_remove() the call to
mmc_free_host() frees private driver data, therefore using it afterwards
is a bug. Revert that hunk.

As mmc_start_host is getting called before enabling the dw_mmc controller
interrupt, there is a problem of missing the SDMMC_INT_CMD_DONE for the
very first command sent by the sdio_reset.
This problem occurs only when we disable MMC debugging i.e, MMC_DEBUG=n.
This patch enables the dw_mmc controller interrupt before mmc_start_host.

This is the same as /sys/bus/pci/devices/0000:??:??.?/config access

While copying the argument structures in HYPERVISOR_event_channel_op()
and HYPERVISOR_physdev_op() into the local variable is sufficiently
safe even if the actual structure is smaller than the container one,
copying back eventual output values the same way isn't: This may
collide with on-stack variables (particularly "rc") which may change
between the first and second memcpy() (i.e. the second memcpy() could
discard that change).
Move the fallback code into out-of-line functions, and handle all of
the operations known by this old a hypervisor individually: Some don't
require copying back anything at all, and for the rest use the
individual argument structures' sizes rather than the container's.

Pull more scsi target fixes from Nicholas Bellinger:
"This series is a second round of target fixes for v3.7-rc4 that have
come into target-devel over the last days, and are important enough to
be applied ASAP.
All are being CC'ed to stable. The most important two are:
- target: Re-add explict zeroing of INQUIRY bounce buffer memory to
fix a regression for handling zero-length payloads, a bug that went
during v3.7-rc1, and hit >= v3.6.3 stable. (nab + paolo)
- iscsi-target: Fix a long-standing missed R2T wakeup race in TX
thread processing when using a single queue slot. (Roland)
Thanks to Roland & PureStorage team for helping to track down this
long standing race with iscsi-target single queue slot operation.
Also, the tcm_fc(FCoE) regression bug that was observed recently with
-rc2 code has also been resolved with the cancel_delayed_work() return
bugfix (commit c0158ca64da5: "workqueue: cancel_delayed_work() should
return %false if work item is idle") now in -rc3. Thanks again to Yi
Zou, MDR, Robert Love @ Intel for helping to track this down."

If a PCI device and its parents are put into D3cold, unbinding the
device will trigger deadlock as follow:
- driver_unbind
- device_release_driver
- device_lock(dev) <--- previous lock here
- __device_release_driver
- pm_runtime_get_sync
...
- rpm_resume(dev)
- rpm_resume(dev->parent)
...
- pci_pm_runtime_resume
...
- pci_set_power_state
- __pci_start_power_transition
- pci_wakeup_bus(dev->parent->subordinate)
- pci_walk_bus
- device_lock(dev) <--- deadlock here
If we do not do device_lock in pci_walk_bus, we can avoid deadlock.
Device_lock in pci_walk_bus is introduced in commit:
d71374dafb, corresponding email thread
is: https://lkml.org/lkml/2006/5/26/38. The patch author Zhang Yanmin
said device_lock is added to pci_walk_bus because:
Some error handling functions call pci_walk_bus. For example, PCIe
aer. Here we lock the device, so the driver wouldn't detach from the
device, as the cb might call driver's callback function.
So I fixed the deadlock as follows:
- remove device_lock from pci_walk_bus
- add device_lock into callback if callback will call driver's callback
I checked pci_walk_bus users one by one, and found only PCIe aer needs
device lock.

This I2C master can do DMA and PIOQUEUE (PIO with FIFO). Originally,
only PIOQUEUE was supported and it had issues, then DMA support was added
this cycle. The original intention was to keep PIOQUEUE since it has
less overhead what is nice for small transfers. However, runtime
switching between PIOQEUE and DMA depending on the transfer size never
worked despite a lot of trying. Since PIOQUEUE mode itself was flaky
(polling at places where interrupts failed to work) and the
implementation also imposed a size limit for transfers, it is best to
remove the support, so users don't fall over its limitations. It also
makes the driver a lot cleaner and more robust. If somebody really wants
less overhead, plain PIO mode could still be implemented with the
addidtional advantage that this mode is also available on MX23, too.

When buffer sharing with the i915 and using a 1680x1050 monitor,
the i915 gives is a 6912 buffer for the 6720 width, the code doesn't
render this properly as it uses one value to set the base address for
reading from the vmap and for where to start on the device.
This fixes it by calculating the values correctly for the device and
for the pixmap. No idea how I haven't seen this before now.

On all dual CRTC GPUs the CRTC_CRT_ON in the RADEON_CRTC_EXT_CNTL register
controls the CRTC of the primary DAC. Therefore it is set in the DAC DMPS
function.
This is different for GPU's with a single CRTC but a primary and a
TV DAC: here it controls the single CRTC no matter where it is routed.
Therefore we set it here. This avoids an elaborate on/off state tracking
since both primary_dac_dpms() and tv_dac_dpms() functions would have
to touch this bit.
On single CRTC GPUs with just one DAC it's irrelevant where this bit
is handled.

The Radeon driver uses the analog/digital flag to determine if the
DAC or the TMDS encoder should be enabled on a DVI-I connector.
If the EDID is bogus this flag is no longer reliable. This fix
adds a fallback to DAC load detection to determine if anything
is connected to the DAC. If not and a (bogus) EDID is found it
assumes a digital display is connected.
This works around problems with some crappy IPMI devices using
Radeon ES1000.

The sleeping code in iscsi_target_tx_thread() is susceptible to the classic
missed wakeup race:
- TX thread finishes handle_immediate_queue() and handle_response_queue(),
thinks both queues are empty.
- Another thread adds a queue entry and does wake_up_process(), which does
nothing because the TX thread is still awake.
- TX thread does schedule_timeout() and sleeps forever.
In practice this can kill an iSCSI connection if for example an initiator
does single-threaded writes and the target misses the wakeup window when
queueing an R2T; in this case the connection will be stuck until the
initiator loses patience and does some task management operation (or kills
the connection entirely).
Fix this by converting to wait_event_interruptible(), which does not
suffer from this sort of race.

When crtc_funcs->dpms callback is called, exynos_crtc->dpms
and exynos_encoder->dpms are changed to new mode. But if user
requests dpms mode operation, OFF -> ON, when crtc's dpms callback
is called, exynos_encoder->dpms is also changed to ON. This
makes encoder's dpms callback call be ignored so display power
couldn't become on again.
This patch removes exynos_encoder->dpms changing and adds 'updated'

Microsoft Digital Media Keyboard 3000 has two interfaces, and the
second one has a report descriptor with a bug. The second collection
says:
05 01 -- global; usage page -- 01 -- Generic Desktop Controls
09 80 -- local; usage -- 80 -- System Control
a1 01 -- main; collection -- 01 -- application
85 03 -- global; report ID -- 03
19 00 -- local; Usage Minimum -- 00

15 00 -- global; Logical Minimum -- 0
26 ff 00 -- global; Logical Maximum -- ff
81 00 -- main; input

I.e. it makes us think that there are all kinds of usages of system
control. That the keyboard is a not only a keyboard, but also a
joystick, mouse, gamepad, keypad, etc. The same as for the Wireless
Desktop Receiver, this should be Physical Min/Max. So fix that
appropriately.

Commit 2863b9eb didn't take into account the changes to add TRIM support to
RAID10 (commit 532a2a3fb). That is, when using dm-raid.c to create the
RAID10 arrays, there is no mddev->gendisk or mddev->queue. The code added
to support TRIM simply assumes that mddev->queue is available without
checking. The result is an oops any time dm-raid.c attempts to create a
RAID10 device.

setup_conf in raid1.c uses conf->raid_disks before assigning
a value. It is used when including 'Replacement' devices.
The consequence is that assembling an array which contains a
replacement will misbehave and either not include the replacement, or
not include the device being replaced.
Though this doesn't lead directly to data corruption, it could lead to
reduced data safety.
So use mddev->raid_disks, which is initialised, instead.

Due to the SMP nature of some of the chips, which have per CPU
registers, the driver does not use the generic irq_gc_mask_set_bit() &
irq_gc_mask_clr_bit() functions, which only support a single register.
The driver has its own implementation of these functions, which can
pick the correct register depending on the CPU being used. The
functions do however use the gc->mask_cache value.
The call to irq_setup_generic_chip() was passing
IRQ_GC_INIT_MASK_CACHE, which caused the gc->mask_cache to be
initialized to the contents of some random register. This resulted in
unexpected interrupts been delivered from random GPIO lines.

The ath9k xmit functions for AMPDUs can send frames as non-aggregate in case
only one frame is currently available. The client will then answer using a
normal Ack instead of a BlockAck. This acknowledgement has no TID stored and
therefore the hardware is not able to provide us the corresponding TID.
The TID set by the hardware in the tx status descriptor has to be seen as
undefined and not as a valid TID value for normal acknowledgements. Doing
otherwise results in a massive amount of retransmissions and stalls of
connections.
Users may experience low bandwidth and complete connection stalls in
environments with transfers using multiple TIDs.
This regression was introduced in b11b160def
("ath9k: validate the TID in the tx status information").

xfstests has always had random failures of tests due to loop devices
failing to be torn down and hence leaving filesytems that cannot be
unmounted. This causes test runs to immediately stop.
Over the past 6 or 7 years we've added hacks like explicit unmount
-d commands for loop mounts, losetup -d after unmount -d fails, etc,
but still the problems persist. Recently, the frequency of loop
related failures increased again to the point that xfstests 259 will
reliably fail with a stray loop device that was not torn down.
That is despite the fact the test is above as simple as it gets -
loop 5 or 6 times running mkfs.xfs with different paramters:
lofile=$(losetup -f)
losetup $lofile "$testfile"
"$MKFS_XFS_PROG" -b size=512 $lofile >/dev/null || echo "mkfs failed!"
sync
losetup -d $lofile
And losteup -d $lofile is failing with EBUSY on 1-3 of these loops
every time the test is run.
Turns out that blkid is running simultaneously with losetup -d, and
so it sees an elevated reference count and returns EBUSY. But why
is blkid running? It's obvious, isn't it? udev has decided to try
and find out what is on the block device as a result of a creation
notification. And it is racing with mkfs, so might still be scanning
the device when mkfs finishes and we try to tear it down.
So, make losetup -d force autoremove behaviour. That is, when the
last reference goes away, tear down the device. xfstests wants it
*gone*, not causing random teardown failures when we know that all
the operations the tests have specifically run on the device have
completed and are no longer referencing the loop device.

Since commit 070ad7e ("floppy: convert to delayed work and single-thread
wq"), we end up calling alloc_ordered_workqueue multiple times inside
the loop, which shouldn't be intended. Besides the leak, other side
effect in the current code is if blk_init_queue fails, we would end up
calling unregister_blkdev even if we didn't call yet register_blkdev.
Just moved the allocation of floppy_wq before the loop, and adjusted the
code accordingly.

bf->bf_next is only while buffers are chained as part of an A-MPDU
in the tx queue. When a tid queue is flushed (e.g. on tearing down
an aggregation session), frames can be enqueued again as normal
transmission, without bf_next being cleared. This can lead to the
old pointer being dereferenced again later.
This patch might fix crashes and "Failed to stop TX DMA!" messages.

Arbitrarily selecting GPIOLIB causes trouble on some architectures,

depend on CONFIG_I2C_MUX_GPIO instead of CONFIG_I2C_MUX for now. We

The problem is that of_device_id->data is a const void pointer.

&qpti_template.

This change was originally titled "gpio/omap: fix off-mode bug: clear debounce
clock enable mask on free/reset". The title has been updated slightly to
reflect (what should be) the final fix.
When a GPIO is freed or shutdown, we need to ensure that any debounce settings
are cleared and if the GPIO is the only GPIO in the bank that is currently
using debounce, then disable the debounce clock as well to save power.
Currently, the debounce settings are not cleared on a GPIO free or shutdown and
so during a context restore on subsequent off-mode transition, the previous
debounce values are restored from the shadow copies (bank->context.debounce*)
leading to mismatch state between driver state and hardware state.
This was discovered when board code was doing
gpio_request_one()
gpio_set_debounce()
gpio_free()
which was leaving the GPIO debounce settings in a confused state. If that GPIO
bank is subsequently used with off-mode enabled, bogus state would be restored,
leaving GPIO debounce enabled which then prevented the CORE powerdomain from
transitioning.
To fix this, introduce a new function called _clear_gpio_debounce() to clear
any debounce settings when the GPIO is freed or shutdown. If this GPIO is the
last debounce-enabled GPIO in the bank, the debounce will also be cut.
Please note that we cannot use _gpio_dbck_disable() to disable the debounce
clock because this has been specifically created for the gpio suspend path
and is intended to shutdown the debounce clock while debounce is enabled.
Special thanks to Kevin Hilman for root causing the bug. This fix is a
collaborative effort with inputs from Kevin Hilman, Grazvydas Ignotas and
Santosh Shilimkar.
Testing:
- This has been unit tested on an OMAP3430 Beagle board, by requesting a gpio,
enabling debounce and then freeing the gpio and checking the register
contents, the saved register context and the debounce clock state.
- Kevin Hilman tested on 37xx/EVM board which configures GPIO debounce for the
ads7846 touchscreen in its board file using the above sequence, and so was
failing off-mode tests in dynamic idle. Verified that off-mode tests are
passing with this patch.

With kernel 3.6 some obsolete SCSI-2 commands including SEEK_10 have
have been removed by commit 1fd032ee10
"target: move code for CDB emulation".
There are still clients out there which use these old SCSI-2 commands.
This mainly happens when running VMs with legacy guest systems,
connected via SCSI command pass-through to iSCSI targets. Make them
happy and return status GOOD.
Many real SCSI disks or external iSCSI storage devices still support
these old commands. So let's make LIO backward compatible as well.
This patch adds support for the previously removed SEEK_10 and
additionally the SEEK_6 and REZERO_UNIT commands.

Fabric drivers currently expect to internally release se_cmd in the event
of a TMR failure during target_submit_tmr(), which means the immediate call
to transport_generic_free_cmd() after TFO->queue_tm_rsp() from within
target_complete_tmr_failure() workqueue context is wrong.
This is done as some fabrics expect TMR operations to be acknowledged
before releasing the descriptor, so the assumption that core is releasing
se_cmd associated TMR memory is incorrect. This fixes a OOPs where
transport_generic_free_cmd() was being called more than once.
This bug was originally observed with tcm_qla2xxx fabric ports.

It is possible for the target code to change the loop_id or s_id of a
target session in reaction to an FC fabric change. However, the
session structures are stored in tables that are indexed by these two
keys, and if we just change the session structure but leave the
pointers to it in the old places in the table, havoc can ensue. For
example, a new session might come along that should go in the old slot
in the table and overwrite the old session pointer.
To handle this, add a new tgt_ops->update_sess() method that also
updates the "by loop_id" and "by s_id" lookup tables when a session
changes, so that the keys where a session pointer is stored in these
tables always matches the keys in the session structure itself.

My draft of SPC-4 says the following about the SCSI name string in
inquiry VPD page 83h:
The SCSI NAME STRING field starts with either:
a) the four UTF-8 characters 'eui.' concatenated with 16, 24, or
32 hexadecimal digits (i.e., the UTF-8 characters 0 through 9
and A through F) for an EUI-64 based identifier (see
7.8.6.5). The first hexadecimal digit shall be the most
significant four bits of the first byte (i.e., most significant
byte) of the EUI-64 based identifier;
b) the four UTF-8 characters 'naa.' concatenated with 16 or 32
hexadecimal digits for an NAA identifier (see 7.8.6.6). The
first hexadecimal digit shall be the most significant four bits
of the first byte (i.e., most significant byte) of the NAA
identifier; or
c) the four UTF-8 characters 'iqn.' concatenated with an iSCSI
Name for an iSCSI-name based identifier (see iSCSI).
However, the .tpg_get_wwn method for tcm_qla2xxx formats the WWN so
the SCSI name string looks like "52:4a:93:7d:24:5f:b2:12,t,0x0001".
This patch corrects the code so that VPD 83h gives a SPC-compliant
SCSI name string like "naa.524a937d245fb212,t,0x0001" while leavig
other uses alone (so configfs will still work with ':' separated WWNs).

problems.) Thanks to Johan Hovold for finding the problems and fixing
them all up.
Other than those, there is the usual new device ids, xhci bugfixes,
and gadget driver fixes, nothing out of the ordinary.

Driver anchors the tx urbs and defers the urb submission if
a transmit request comes when the interface is suspended.
Anchoring urb increments the urb reference count. These
deferred urbs are later accessed by calling usb_get_from_anchor()
for submission during interface resume. usb_get_from_anchor()
unanchors the urb but urb reference count remains same.
This causes the urb reference count to remain non-zero
after usb_free_urb() gets called and urb never gets freed.
Hence call usb_put_urb() after anchoring the urb to properly
balance the reference count for these deferred urbs. Also,
unanchor these deferred urbs during disconnect, to free them
up.

The delayed work function int_in_work() may call usb_reset_device()
and thus, indirectly, the driver's pre_reset method. Trying to
cancel the work synchronously in that situation would deadlock.
Fix by avoiding cancel_work_sync() in the pre_reset method.
If the reset was NOT initiated by int_in_work() this might cause
int_in_work() to run after the post_reset method, with urb_int_in
already resubmitted, so handle that case gracefully.

Like our other pen-and-touch products, the Cintiq 24HD touch needs data
to be shared between its two sensors to facilitate proximity-based palm
rejection.
Unlike other tablets that report sensor data through separate interfaces
of the same USB device, the Cintiq 24HD touch has separate USB devices
that are connected to an internal USB hub.
This patch makes it possible to designate the USB VID/PID of the other
device so that the two may share data. To ensure we don't accidentally
link to a sensor from a physically separate device (if several have been
plugged in), we limit the search to siblings (i.e., devices directly
connected to the same hub).

The dw_dmac driver was originally developed for avr32 to be used with the
Synopsys DesignWare AHB DMA controller. Starting from 2.6.38, access to
the device's i/o memory was done with the little-endian readl/writel
functions(1)
This broke the driver for the avr32 platform, because it needs big
(native) endian accessors. This patch makes the endianness configurable
using 'DW_DMAC_BIG_ENDIAN_IO', which will default be true for AVR32

Coverity complains that xhci_evaluate_context_result() is missing a

statement below it does. The end result would be one that a Slot

associated with a Context State error code. No other bad behavior would
result.

The command cancellation code doesn't check whether find_trb_seg()
couldn't find the segment that contains the TRB to be canceled. This
could cause a NULL pointer deference later in the function when next_trb

command ring pointers, so add some debugging in case it happens.

Fix port-data memory leak in usb-serial probe error path by moving port
data allocation to port_probe.
Since commit a1028f0abf ("usb: usb_wwan: replace release and disconnect
with a port_remove hook") port data is deallocated in port_remove. This
leaves a possibility for memory leaks if usb-serial probe fails after
attach but before the port in question has been successfully registered.
Note that this patch also fixes two additional memory leaks in the error
path of attach should port initialisation fail for any port as the urbs
were never freed and neither was the data of any of the successfully
initialised ports.

The driver relies on the generic write implementation but did not call
generic close.
Note that the call to kill the read urb is not redundant, as mct_u232
uses an interrupt urb from the second port as the read urb and that

If dsi_get_dsidev_from_id() is called with a DSI module id that does not
exist on the board, the function will crash as omap_dss_get_output()
will return NULL.
This happens on omap3 boards when dumping DSI clocks, as the dumping
code will try to get the dsidev for DSI modules 0 and 1, but omap3 only
has DSI module 0.
Also clean up the id -> output mapping, so that if the function is
called with invalid module ID it will return NULL.

The irq_to_gpio() is old, most platforms use GENERIC_GPIO framework
and don't support this API anymore.
The i.MX6q sabrelite platform equips an egalax touchscreen controller,
and this platform already transfered to GENERIC_GPIO framework, to
support this driver, we use a more generic way to get gpio.
Add a return value checking for waking up the controller in the probe
function, this guarantee only a workable device can pass init.

Investigating the source of the message leads one to the
