Pull spi fixes from Mark Brown:
"A few core fixes around outlying cases here, nothing that should
affect most users but useful fixes. The diffstat is rather larger
than one might hope due some simple code motion in the fix for

- Fix handling of unsupported dual and quad mode support on slave

mapping support.

Pull ACPI and power management fixes from Rafael Wysocki:
"Still fixing regressions (partly by reverting commits that broke
things for people), fixing other stable-candidate bugs and adding some
blacklist entries for ACPI video and _OSI.
Two ACPICA regression fixes (one recent and one for a 3.14 commit), a
fix for an ACPI-related regression in TPM (introduced in 3.14), a
revert of the ACPI AC driver conversion in 3.13 that went wrong for an
unknown reason, two reverts of commits that attempted to remove an old
user space interface in /proc and broke some utilities, in 3.13 too, a
fix for a CPU hotplug bug in the ACPI processor driver (stable
material), two (stable candidate) fixes for intel_pstate and a few new
blacklist entries, mostly for systems that shipped with Windows 8.
Specifics:
- ACPICA fix for a stale pointer access introduced by a recent commit
in the XSDT validation code from Lv Zheng.
- ACPICA fix for the default value of the command line switch to
favor 32-bit FADT addresses (in case there's a conflict between a
64-bit and a 32-bit address). The previous default was that the
32-bit version would take precedence and we tried to change it to
the other way around and it didn't work. From Lv Zheng.
- A TPM commit related to ACPI _DSM in 3.14 caused the driver to
refuse to load if a specific _DSM was missing and that broke resume
from system suspend on Chromebooks that require the TPM hardware to
be restored to a working state during resume by the OS. Restore
the old behavior to load the driver if the _DSM in question is not
present, but prevent it from using the feature the _DSM is for.
- ACPI AC driver conversion in 3.13 broke thermal management on at
least one machine and has to be reverted. From Guenter Roeck.
- Two reverts of 3.13 commits that attempted to remove the old ACPI
battery interface in /proc, but turned out to break some utilities
still using that interface. From Lan Tianyu.
- ACPI processor driver fix to prevent acpi_processor_add() from
modifying the CPU device's .offline field which leads to breakage
if the initial online of the CPU fails. From Igor Mammedov.
- Two intel_pstate fixes, one to take a BayTrail documentation update
into account and one to avoid forcing the maximum P-state on init
which causes CPU PM trouble on systems with P-states coordination
when one of the CPU cores is initialized after an offline/online
cycle triggered by user space. Both stable candidates, from Dirk
Brandewie.
- Fix for the ACPI video DMI blacklist entry for Dell Inspiron 7520
from Aaron Lu.
- Two new ACPI video blacklist entries for machines shipping with
Win8 that need to use native backlight so that it can be controlled
in a usual way (which doesn't work otherwise due bugs in the ACPI
tables) from Hans de Goede.
- Two ACPI _OSI quirks for systems that need them to work correctly
with Linux from Edward Lin and Hans de Goede"

As remarked by Christopher R. Baker in his post at
http://marc.info/?l=linux-can&m=139707295706465&w=2
there's a possibility for an use after free condition at device removal.
This simplified patch introduces an additional variable to prevent the issue.
Thanks for catching this.

The sa11x0_dma_pm_ops unconditionally reference sa11x0_dma_resume
and sa11x0_dma_suspend, which currently breaks if CONFIG_PM_SLEEP
is disabled.
There is probably a better way to remove the reference in this
case, but the safe choice is to have the suspend/resume code always
built in the driver.

Commit 85ad643b ("dm thin: add timeout to stop out-of-data-space mode
holding IO forever") introduced a fixed 60 second timeout. Users may
want to either disable or modify this timeout.
Allow the out-of-data-space timeout to be configured using the
'no_space_timeout' dm-thin-pool module param. Setting it to 0 will
disable the timeout, resulting in IO being queued until more data space
is added to the thin-pool.

This driver is using devres managed calls incorrectly, giving the cpu0
device as first parameter instead of the cpufreq platform device.
This results in resources not being freed if the cpufreq platform device

The commit e783c51 (ahci: imx: software workaround for phy reset issue
in resume) calls imx_sata_phy_reset() to reset phy immediately after
SATA MPLL is enabled. It seems working fine mostly, but fails in some
case as below.
...
ahci-imx 2200000.sata: failed to reset phy: -110
ahci-imx: probe of 2200000.sata failed with error -110
After talking to the designer, we learnt that when enabling i.MX6Q SATA
MPLL, we need to wait 100us for it to settle down for safety. Add this
required delay to fix above failure.

In 2b9aecdce2 ("can: c_can: Disable rx split as workaround") a new Kconfig
option was introduced as a workaround. The tests performed by Alexander Stein
confirmed this option to be obsolete with all the other cleanups and fixes
that had been discussed that time:
http://marc.info/?l=linux-can&m=139746476821294&w=2
Both (author and tester) agreed to remove this Kconfig option again:
http://marc.info/?l=linux-can&m=139883820714229&w=2
As some more cleanups took place since then a simple revert is not possible.
This patch removes the entire option as it would behave when disabled.
Further beautification’s can be done later.

On each processed XCOPY command, two "kmalloc-512" memory objects are
leaked. These represent two allocations of struct xcopy_pt_cmd in
target_core_xcopy.c.
The reason for the memory leak is that the cmd_kref field is not
initialized (thus, it is zero because the allocations were done with
kzalloc). When we decrement zero kref in target_put_sess_cmd, the result
is not zero, thus target_release_cmd_kref is not called.
This patch fixes the bug by moving kref initialization from
target_get_sess_cmd to transport_init_se_cmd (this function is called from
target_core_xcopy.c, so it will correctly initialize cmd_kref). It can be
easily verified that all code that calls target_get_sess_cmd also calls
transport_init_se_cmd earlier, thus moving kref_init shouldn't introduce
any new problems.

Prior to commit fbd929f2dce460456807a51e18d623db3db9f077
bonding: support QinQ for bond arp interval
the arp monitoring code allowed for proper detection of devices
stacked on top of vlans. Since the above commit, the
code can still detect a device stacked on top of single
vlan, but not a device stacked on top of Q-in-Q configuration.
The search will only set the inner vlan tag if the route
device is the vlan device. However, this is not always the
case, as it is possible to extend the stacked configuration.
With this patch it is possible to provision devices on
top Q-in-Q vlan configuration that should be used as
a source of ARP monitoring information.
For example:
ip link add link bond0 vlan10 type vlan proto 802.1q id 10
ip link add link vlan10 vlan100 type vlan proto 802.1q id 100
ip link add link vlan100 type macvlan
Note: This patch limites the number of stacked VLANs to 2,
just like before. The original, however had another issue
in that if we had more then 2 levels of VLANs, we would end
up generating incorrectly tagged traffic. This is no longer
possible.

Macvlan devices try to avoid stacking, but that's not always
successfull or even desired. As an example, the following
configuration is perefectly legal and valid:
eth0 <--- macvlan0 <---- vlan0.10 <--- macvlan1

When the NAPI budget was not all used, xenvif_poll() would call
napi_complete() /after/ enabling the interrupt. This resulted in a
race between the napi_complete() and the napi_schedule() in the
interrupt handler. The use of local_irq_save/restore() avoided by
race iff the handler is running on the same CPU but not if it was
running on a different CPU.
Fix this properly by calling napi_complete() before reenabling
interrupts (in the xenvif_napi_schedule_or_enable_irq() call).

====================
pull request: wireless 2014-05-15
Please pull this batch of fixes for the 3.15 stream...
For the mac80211 bits, Johannes says:
"One fix is to get better VHT performance and the other fixes tracing
garbage or other potential issues with the interface name tracing."
And...
"This has a fix from Emmanuel for a problem I failed to fix - when
association is in progress then it needs to be cancelled while
suspending (I had fixed the same for authentication). Also included a
fix from myself for a userspace API problem that hit the iw tool and a
fix to the remain-on-channel framework."
For the iwlwifi bits, Emmanuel says:
"Alex fixes the scan by disabling the fragmented scan. David prevents
scan offload while associated, the firmware seems not to like it. I
fix a stupid bug I made in BT Coex, and fix a bad #ifdef clause in rate
scaling. Along with that there is a fix for a NULL pointer exception
that can happen if we load the driver and our ISR gets called because
the interrupt line is shared. The fix has been tested by the reporter."
And...
"We have here a fix from David Spinadel that makes a previous fix more
complete, and an off-by-one issue fixed by Eliad in the same area.
I fix the monitor that broke on the way."
Beyond that...
Daniel Kim's one-liner fixes a brcmfmac regression caused by a typo
in an earlier commit..
Rajkumar Manoharan fixes an ath9k oops reported by David Herrmann.
