commit 8a487b1a74 upstream.
When the queue is unmapped while it was so loaded that
mac80211's was stopped, we need to wake the queue after
having freed all the packets in the queue.
Not doing so can result in weird stuff like:
* run lots of traffic (mac80211's queue gets stopped)
* RFKILL
* de-assert RFKILL
* no traffic

commit b967613d7e upstream.
When a queue is disabled, it frees all its entries. Later,
the op_mode might still get notifications from the firmware
that triggers to free entries in the tx queue. The transport
should be prepared for these races and know to ignore
reclaim calls on queues that have been disabled and whose
entries have been freed.

commit fbf33f516b upstream.
Commit 4f535093cf "PCI: Put pci_dev in device tree as early as possible"
moves device registering from pci_bus_add_devices() to pci_device_add().
That causes problems for virtual functions because device_add(&virtfn->dev)
is called before setting the virtfn->is_virtfn flag, which then causes Xen
to report PCI virtual functions as PCI physical functions.
Fix it by setting virtfn->is_virtfn before calling pci_device_add().
[Jiang Liu]: Move the setting of virtfn->is_virtfn ahead further for better
readability and modify changelog.

commit c378f70adb upstream.
Currently, when a disconnect is requested by the user (via NBD_DISCONNECT
ioctl) the return from NBD_DO_IT is undefined (it is usually one of
several error codes). This means that nbd-client does not know if a
manual disconnect was performed or whether a network error occurred.
Because of this, nbd-client's persist mode (which tries to reconnect after
error, but not after manual disconnect) does not always work correctly.
This change fixes this by causing NBD_DO_IT to always return 0 if a user
requests a disconnect. This means that nbd-client can correctly either
persist the connection (if an error occurred) or disconnect (if the user
requested it).

commit 91bdad0b62 upstream.
The role of acpi_bus_update_power() is to update the given ACPI
device object's power.state field to reflect the current physical
state of the device (as inferred from the configuration of power
resources and _PSC, if available). For this purpose it calls
acpi_device_set_power() that should update the power resources'
reference counters and set power.state as appropriate. However,
that doesn't work if the "new" state is D1, D2 or D3hot and the
the current value of power.state means D3cold, because in that
case acpi_device_set_power() will refuse to transition the device
from D3cold to non-D0.
To address this problem, make acpi_bus_update_power() call
acpi_power_transition() directly to update the power resources'
reference counters and only use acpi_device_set_power() to put
the device into D0 if the current physical state of it cannot
be determined.

commit 2fa97feb44 upstream.
On HP Folio 13-2000, the BIOS defines a CMOS RTC Operation Region and
the EC's _REG methord accesses that region. Thus an appropriate
address space handler must be registered for that region before the
EC driver is loaded.
Introduce a mechanism for adding CMOS RTC address space handlers.
Register an ACPI scan handler for CMOS RTC devices such that, when
a device of that kind is detected during an ACPI namespace scan, a
common CMOS RTC operation region address space handler will be
installed for it.

commit 098b1aeaf4 upstream.
There are two tool-stack that can instruct the Xen PCI frontend
and backend to change states: 'xm' (Python code with a daemon),
and 'xl' (C library - does not keep state changes).
With the 'xm', the path to disconnect a single PCI device (xm pci-detach
<guest> <BDF>) is:
4(Connected)->7(Reconfiguring*)-> 8(Reconfigured)-> 4(Connected)->5(Closing*).
The * is for states that the tool-stack sets. For 'xl', it is similar:
4(Connected)->7(Reconfiguring*)-> 8(Reconfigured)-> 4(Connected)
Both of them also tear down the XenBus structure, so the backend
state ends up going in the 3(Initialised) and calls pcifront_xenbus_remove.
When a PCI device is plugged back in (xm pci-attach <guest> <BDF>)
both of them follow the same pattern:
2(InitWait*), 3(Initialized*), 4(Connected*)->4(Connected).
[xen-pcifront ignores the 2,3 state changes and only acts when
4 (Connected) has been reached]
Note that this is for a _single_ PCI device. If there were two
PCI devices and only one was disconnected 'xm' would show the same
state changes.
The problem is that git commit 3d925320e9
("xen/pcifront: Use Xen-SWIOTLB when initting if required") introduced
a mechanism to initialize the SWIOTLB when the Xen PCI front moves to
Connected state. It also had some aggressive seatbelt code check that
would warn the user if one tried to change to Connected state without
hitting first the Closing state:
pcifront pci-0: PCI frontend already installed!
However, that code can be relaxed and we can continue on working
even if the frontend is instructed to be the 'Connected' state with
no devices and then gets tickled to be in 'Connected' state again.
In other words, this 4(Connected)->5(Closing)->4(Connected) state
was expected, while 4(Connected)->.... anything but 5(Closing)->4(Connected)
was not. This patch removes that aggressive check and allows
Xen pcifront to work with the 'xl' toolstack (for one or more
PCI devices) and with 'xm' toolstack (for more than two PCI
devices).

commit f51e1eb63d upstream.
Toralf Förster reported that the cpufreq ondemand governor behaves erratically
(doesn't scale well) after a suspend/resume cycle. The problem was that the
cpufreq subsystem's idea of the cpu frequencies differed from the actual
frequencies set in the hardware after a suspend/resume cycle. Toralf bisected
the problem to commit a66b2e5 (cpufreq: Preserve sysfs files across
suspend/resume).
Among other (harmless) things, that commit skipped the call to
cpufreq_update_policy() in the resume path. But cpufreq_update_policy() plays
an important role during resume, because it is responsible for checking if
the BIOS changed the cpu frequencies behind our back and resynchronize the
cpufreq subsystem's knowledge of the cpu frequencies, and update them
accordingly.
So, restore the call to cpufreq_update_policy() in the resume path to fix
the cpufreq regression.

In line 2908 we can find the copy_to_user function:

The cgc->buffer is never cleaned and initialized before this function.
If ret = 0 with the previous basic block, it's possible to display some
memory bytes in kernel space from userspace.
When we read a block from the disk it normally fills the ->buffer but if
the drive is malfunctioning there is a chance that it would only be
partially filled. The result is an leak information to userspace.

rbd: send snapshot context with writes
Sending the right snapshot context with each write is required for
snapshots to work. Due to the ordering of calls, the snapshot context
is never set for any requests. This causes writes to the current
version of the image to be reflected in all snapshots, which are
supposed to be read-only.
This happens because rbd_osd_req_format_write() sets the snapshot
context based on obj_request->img_request. At this point, however,
obj_request->img_request has not been set yet, to the snapshot context
is set to NULL. Fix this by moving rbd_img_obj_request_add(), which
sets obj_request->img_request, before the osd request formatting
calls.

Pull regulator fix from Mark Brown:
"Fix module loading for tps6586x.
A simple one liner fix to make module loading work for distros
(product specific kernels tend to have things built in)"
* tag 'regulator-v3.10-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator:
mfd: tps6586x: correct device name of the regulator cell
Pull GPIO regression fix from Grant Likely:
"It took a while to work out the correct solution to this regression.
It is sorted now. This branch was constructed and tested by Tony.
I've verified that it builds and signed the tag"
* tag 'gpio-for-linus' of git://git.secretlab.ca/git/linux:
gpio/omap: don't use linear domain mapping for OMAP1
Pull late power management and ACPI fixes from Rafael Wysocki:
"Sorry about the timing of this, but ACPI-based docking stations with
PCI devices on them and ATA bays would be hardly usable with 3.10
without it. We've been working on these fixes for the last couple of
weeks and everyone involved appears to be reasonably comfortable with
them now.
The PM part is one fix for a cpufreq regression introduced recently
- Fix for an ACPI dock regression introduced by the recent rework of
the ACPI-based PCI hotplug code (acpiphp) that caused it to be
initialized before the ACPI dock driver, which is incorrect (ACPI
dock has to be initialized before acpiphp so that acpiphp can
register PCI devices on docking stations with it for PCI hotplug on
re-dock to work). From Jiang Liu.
- Fix for PCI resources allocation in the ACPI-based PCI hotplug code
(acpiphp) that makes it use the same PCI resources assignment rules
during runtime hotplug that are used during boot (the BIOS' choices
are now respected in both cases). This prevents PCI resource
allocation failures during hotplug from happening in some cases.
From Jiang Liu.
- Fix for ordering and synchronization issues during hot-removal of
PCI devices on docking stations. It makes the ACPI dock code carry
out the PCI devices removal synchronously during undock instead of
spawning a separate asynchronous work item to remove each of them
without even bothering to wait for all those work items to
complete. The hot-addition part is changed analogously.
- Fix for a regression (introduced a few releases ago) that removed
the code to register a hotplug notificaion handler for for ATA
ports/devices inadvertently which prevented ATA bays hotplug from
working. The missing code is added back with some improvements.
From Aaron Lu.
- Fix for a recent cpufreq regression causing a NULL pointer
dereference to trigger in od_set_powersave_bias() in some
situations from Jacob Shin"
* tag 'pm+acpi-3.10-late' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
cpufreq: fix NULL pointer deference at od_set_powersave_bias()
libata-acpi: add back ACPI based hotplug functionality
ACPI / dock / PCI: Synchronous handling of dock events for PCI devices
PCI / ACPI: Use boot-time resource allocation rules during hotplug
ACPI / dock: Initialize ACPI dock subsystem upfront
