coretemp_init loops with for_each_online_cpu, adding platform_devices
and sysfs interfaces, then calls register_hotcpu_notifier. There is a
race if a CPU is offlined or onlined after the loop, but before
register_hotcpu_notifier. The race might result in the absence of a
platform_device+sysfs interface for an online CPU, or the presence of
a platform_device+sysfs interface for an offline CPU. A similar race
occurs during coretemp_exit, after the module calls
unregister_hotcpu_notifier, but before it unregisters all devices, a

short while.
This fix surrounds for_each_online_cpu and register_hotcpu_notifier

This patch fixes an issue introduced after commit 4ea5454203
("HID: Fix race condition between driver core and ll-driver").
After that commit, hid-core discards any incoming packet that arrives while
hid driver's probe function is being executed.
This broke the enumeration process of hid-logitech-dj, that must receive
control packets in-band with the mouse and keyboard packets. Discarding mouse
or keyboard data at the very begining is usually fine, but it is not the case
for control packets.
This patch forces a re-enumeration of the paired devices when a packet arrives
that comes from an unknown device.

clk_{un}prepare is mandatory for platforms using common clock framework.
Since these drivers are used by SPEAr platform, which supports common
clock framework, add clk_{un}prepare() support for them. Otherwise
the clocks are not correctly en-/disabled and ethernet support doesn't

vfoi-pci supports a mechanism like KVM's irqfd for unmasking an
interrupt through an eventfd. There are two ways to shutdown this
interface: 1) close the eventfd, 2) ioctl (such as disabling the
interrupt). Both of these do the release through a workqueue,
which can result in a segfault if two jobs get queued for the same
virqfd.
Fix this by protecting the pointer to these virqfds by a spinlock.
The vfio pci device will therefore no longer have a reference to it
once the release job is queued under lock. On the ioctl side, we
still flush the workqueue to ensure that any outstanding releases
are completed.

fixes a resume regression on pre-r6xx asics.
* 'drm-fixes-3.6' of git://people.freedesktop.org/~agd5f/linux:
drm/radeon: Prevent leak of scratch register on resume from suspend
Cards typically have 5-7 scratch registers; one of these is reserved for
rdev->rptr_save_reg. Unfortunately the reservation is done in function
r100_cp_init, which is called by all drivers except r600 - and this
function is also invoked on resume from suspend. After several resumes,
no scratch registers are free and graphics acceleration is disabled.
Dmesg then reports either:
*ERROR* radeon: cp failed to get scratch reg (-22).
*ERROR* radeon: cp isn't working(-22).
radeon 0000:01:00.0: failed initializing CP (-22).
or:
*ERROR* radeon: failed to get scratch reg (-22).
*ERROR* radeon: failed testing IB on GFX ring (-22).
*ERROR* ib ring test failed (-22).
The chain of calls on boot for all except r600 is:
radeon_init -> ... -> (rXXX_init) -> rXXX_startup -> r100_cp_init
The chain of calls on resume for all except r600 is:
rXXX_resume -> rXXX_startup -> r100_cp_init.
R600 correctly allocates rptr_save_reg in r600_init (ie once only, not
in resume). However moving the code into the init functions for all
drivers means touching 4 drivers. So instead, this patch just adds a
test in r100_cp_init to avoid reallocating on resume. As the rdev
structure is allocated via kzalloc in radeon_driver_load_kms, and zero
is not a valid registerid, zero safely implies not-yet-allocated.

Merge tag 'v3.6-rc5' into for-linus
Sync with mainline so that I can revert an input patch that came in through
another subsystem tree.
powernowk8_target() runs off a per-cpu work item and if the
cpufreq_policy->cpu is different from the current one, it migrates the
kworker to the target CPU by manipulating current->cpus_allowed. The
function migrates the kworker back to the original CPU but this is
still broken. Workqueue concurrency management requires the kworkers
to stay on the same CPU and powernowk8_target() ends up triggerring
BUG_ON(rq != this_rq()) in try_to_wake_up_local() if it contends on
fidvid_mutex and sleeps.
It is unclear why this bug is being reported now. Duncan says it
appeared to be a regression of 3.6-rc1 and couldn't reproduce it on
3.5. Bisection seemed to point to 63d95a91 "workqueue: use @pool
instead of @gcwq or @cpu where applicable" which is an non-functional
change. Given that the reproduce case sometimes took upto days to
trigger, it's easy to be misled while bisecting. Maybe something made
contention on fidvid_mutex more likely? I don't know.
This patch fixes the bug by using work_on_cpu() instead if @pol->cpu
isn't the same as the current one. The code assumes that
cpufreq_policy->cpu is kept online by the caller, which Rafael tells
me is the case.
stable: ed48ece27c ("workqueue: reimplement work_on_cpu() using
system_wq") should be applied before this; otherwise, the
behavior could be horrible.

Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=47301
It isn't always necessary to update the metadata when spares are
removed as the presence-or-not of a spare isn't really important to
the integrity of an array.
Also activating a spare doesn't always require updating the metadata
as the update on 'recovery-completed' is usually sufficient.
However the introduction of 'replacement' devices have made these
transitions sometimes more important. For example the 'Replacement'
flag isn't cleared until the original device is removed, so we need
to ensure a metadata update after that 'spare' is removed.
So set MD_CHANGE_DEVS whenever a spare is activated or removed, to
complement the current situation where it is set when a spare is added
or a device is failed (or a number of other less common situations).
This is suitable for -stable as out-of-data metadata could lead
to data corruption.
This is only relevant for 3.3 and later 9when 'replacement' as
introduced.
Cc: stable@vger.kernel.org
Signed-off-by: NeilBrown <neilb@suse.de>
When a replacement device becomes active, we mark the device that it
replaces as 'faulty' so that it can subsequently get removed.
However 'calc_degraded' only pays attention to the primary device, not
the replacement, so the array appears to become degraded, which is
wrong.
So teach 'calc_degraded' to consider any replacement if a primary
device is faulty.
This is suitable for -stable as an incorrect 'degraded' value can
confuse md and could lead to data corruption.
This is only relevant for 3.3 and later.

Small random O_DIRECT writes were slower.
Other changes (batching RAID5 writes) have improved the sequential
writes using a different mechanism, so the net result of this patch
is definitely negative. So revert it.

If a command status of CMD_PROTOCOL_ERR is received, this
information should be conveyed to the SCSI mid layer, not
dropped on the floor. CMD_PROTOCOL_ERR may be received
from the Smart Array for any commands destined for an external
RAID controller such as a P2000, or commands destined for tape
drives or CD/DVD-ROM drives, if for instance a cable is
disconnected. This mostly affects multipath configurations, as
disconnecting a cable on a non-multipath configuration is not
going to do anything good regardless of whether CMD_PROTOCOL_ERR
is handled correctly or not. Not handling CMD_PROTOCOL_ERR
correctly in a multipath configaration involving external RAID
controllers may cause data corruption, so this is quite a serious

only affects tape drives and CD and DVD ROM drives in the cciss

On some platforms, bootloaders are known to do some interesting RTC
programming. Without going into the obscurities as to why this may be
the case, suffice it to say the the driver should not make any
assumptions about the state of the RTC when the driver loads. In
particular, the driver probe should be sure that all interrupts are
disabled until otherwise programmed.
This was discovered when finding bursty I2C traffic every second on
Overo platforms. This I2C overhead was keeping the SoC from hitting
deep power states. The cause was found to be the RTC firing every
second on the I2C-connected TWL PMIC.
Special thanks to Felipe Balbi for suggesting to look for a rogue driver
as the source of the I2C traffic rather than the I2C driver itself.
Special thanks to Steve Sakoman for helping track down the source of the
continuous RTC interrups on the Overo boards.

Fix a serious but uncommon bug in nbd which occurs when there is heavy
I/O going to the nbd device while, at the same time, a failure (server,
network) or manual disconnect of the nbd connection occurs.
There is a small window between the time that the nbd_thread is stopped
and the socket is shutdown where requests can continue to be queued to
nbd's internal waiting_queue. When this happens, those requests are
never completed or freed.
The fix is to clear the waiting_queue on shutdown of the nbd device, in
the same way that the nbd request queue (queue_head) is already being
cleared.

This patch fixes the following kernel panic invoked by uninitialized fields
in the chip initialization for the 1G bnx2 iSCSI offload.
One of the bits in the chip initialization is being used by the latest
firmware to control overflow packets. When this control bit gets enabled
erroneously, it would ultimately result in a bad packet placement which would
cause the bnx2 driver to dereference a NULL ptr in the placement handler.
This can happen under certain stress I/O environment under the Linux
iSCSI offload operation.
This change only affects Broadcom's 5709 chipset.

Clear Audio Enable bit to trigger unsolicated event to notify Audio
Driver part the HDMI hot plug change. The patch fixed the bug when
remove HDMI cable the bit was not cleared correctly.
In intel_hdmi_dpms(), if intel_hdmi->has_audio been true, the "Audio enable bit" will
be set to trigger unsolicated event to notify Alsa driver the change.
intel_hdmi->has_audio will be reset to false from intel_hdmi_detect() after
remove the hdmi cable, here's debug log:
[ 187.494153] [drm:output_poll_execute], [CONNECTOR:17:HDMI-A-1] status updated from 1 to 2
[ 187.525349] [drm:intel_hdmi_detect], HDMI: has_audio = 0
so when comes back to intel_hdmi_dpms(), the "Audio enable bit" will not be cleared. And this
cause the eld infomation and pin presence doesnot update accordingly in alsa driver side.
This patch will also trigger unsolicated event to alsa driver to notify the hot plug event:

Pin-leaks persist and we get the perennial bug reports of machine

Read unit address is done for all devices during online processing to read
out LCU features. This is also done after disconnect/connect a LCU.
Some older storage hardware does not provide the capability to read unit
address configuration.
This leads to a loop trying to read unit address configuration every 30
seconds. The device is still operational but logs are flooded with error
messages.
Fix the loop by recognizing a command reject saying that the suborder
for ruac is not supported.

If a new path is available we need to verify the path data. If it is the
first path for a device the stop bits are removed after path verification.
If a pathgroup is established we need to set system characteristics for
the lcu. Therefore I/O has to be started.
If the device is stopped the set system characteristics worker may block
the path verification worker and the device is blocked.
Turn on failfast for set system characteristics CQR to prevent a deadlock
with the path verification worker.
If a pathgroup is established on a device that is not in use trigger path
verification. Maybe we were not informed about a working path.

====================
This is a batch of fixes intended for the 3.6 stream.
Arend van Spriel sends a simple thinko fix to correct a constant,
preventing the setting of an invalid power level.
Colin Ian King gives us a simple allocation failure check to avoid a
NULL pointer dereference.
Felix Fietkau sends another ath9k tx power patch, this time disabling a
feature that has been reported to cause rx problems.
Hante Meuleman provides a pair of endian fixes for brcmfmac.
Larry Finger offers an rtlwifi fix that avoids a system lockup related
to loading the wrong firmware for RTL8188CE devices.
These have been in linux-next for a few days and I think they should be
included in the final 3.6 kernel if possible.

Currently the MFD core supports remapping MFD cell interrupts using an
irqdomain but only if the MFD is being instantiated using device tree
and only if the device tree bindings use the pattern of registering IPs
in the device tree with compatible properties. This will be actively
harmful for drivers which support non-DT platforms and use this pattern
for their DT bindings as it will mean that the core will silently change
remapping behaviour and it is also limiting for drivers which don't do
DT with this particular pattern. There is also a potential fragility if
there are interrupts not associated with MFD cells and all the cells are
omitted from the device tree for some reason.
Instead change the code to take an IRQ domain as an optional argument,
allowing drivers to take the decision about the parent domain for their
interrupts. The one current user of this feature is ab8500-core, it has
the domain lookup pushed out into the driver.

The managed clk functions are currently only available when the generic clk
lookup framework is build. But the managed clk functions are merely wrappers
around clk_get and clk_put and do not depend on any specifics of the generic
lookup functions and there are still quite a few custom implementations of the
clk API. So make the managed functions available whenever the clk API is
implemented.
The patch also removes the custom implementation of devm_clk_get for the
coldfire platform.

commit a606dac368 adds support to link
devices which have _PRx, if a device does not have _PRx, a warning
message will be printed.
This commit is for ZPODD on Intel ZPODD capable platforms, on other
platforms, it has no problem if there is no power resource for this
device, so a warning here is not appropriate, change it to debug.

Commit 3236b2d469 ("IB/qib: MADs with misset M_Keys should return
failure") introduced a return code assignment that unfortunately
introduced an unconditional exit for the routine due to missing braces.
This patch adds the braces to correct the original patch.
