Implement the cfg80211 TDLS channel switch ops and introduce new mac80211
ones for low-level drivers.
Verify low-level driver support for the new ops when using the relevant
wiphy feature bit. Also verify the peer supports channel switching before
passing the command down.
Add a new STA flag to track the off-channel state with the TDLS peer and
make sure to cancel the channel-switch if the peer STA is unexpectedly
removed.

Introduce commands to initiate and cancel TDLS channel-switching. Once
TDLS channel-switching is started, the lower level driver is responsible
for continually initiating channel-switch operations and returning to
the base (AP) channel to listen for beacons from time to time.
Upon cancellation of the channel-switch all communication between the
relevant TDLS peers will continue on the base channel.

For some TDLS channel switch implementations data frames need to be
sent by the firmware based on a template. This template should be
created by mac80211, and thus needs to properly be built from an
802.3 frame into an 802.11 frame. In addition, the device will need
the key information so the select_key handler needs to be run.
However, the driver/device will be responsible for all of the crypto
encapsulation, as the sequence numbers etc. cannot be built by the
host anyway in this case since it's a template to be used multiple
times.

This patch fixes a long standing issue introduced during the 3.16 merge window.
Shortly after the merge, exynos5250-based arndale boards began to produce the
following errors:
kern.err kernel: exynos-cpufreq exynos-cpufreq: failed to set cpu voltage
kern.err kernel: cpufreq: __target_index: Failed to change cpu frequency: -22
Further analysis revealed that the S5M8767 voltage regulator used on the
exynos5250-based arndale board utilizes the S3C2410 I2C controller. If the
S3C2410 I2C controller driver is not enabled, the S5M8767 voltage regulator
fails to probe. Therefore a dependency exists between these two drivers.
In the exynos_defconfig both CONFIG_REGULATOR_S5M8767 and CONFIG_I2C_S3C2410
options are enabled, and no errors are produced. However, in the
multi_v7_defconfig only the CONFIG_REGULATOR_S5M8767 option is enabled and the
errors are present. So let's enable the CONFIG_I2C_S3C2410 option in the
multi_v7_defconfig to allow the S5M8767 voltage regulator to probe.

Before this change it was expected that userspace would first suspend
all active thin devices, reload/resize the thin-pool target, then resume
all active thin devices. Now the thin-pool suspend/resume will trigger
the suspend/resume of all active thins via appropriate calls to
dm_internal_suspend and dm_internal_resume.

these calls possible.

Rename dm_internal_{suspend,resume} to dm_internal_{suspend,resume}_fast
-- dm-stats will continue using these methods to avoid all the extra
suspend/resume logic that is not needed in order to quickly flush IO.
Introduce dm_internal_suspend_noflush() variant that actually calls the
mapped_device's target callbacks -- otherwise target-specific hooks are
avoided (e.g. dm-thin's thin_presuspend and thin_postsuspend). Common
code between dm_internal_{suspend_noflush,resume} and
dm_{suspend,resume} was factored out as __dm_{suspend,resume}.
Update dm_internal_{suspend_noflush,resume} to always take and release
the mapped_device's suspend_lock. Also update dm_{suspend,resume} to be
aware of potential for DM_INTERNAL_SUSPEND_FLAG to be set and respond
accordingly by interruptibly waiting for the DM_INTERNAL_SUSPEND_FLAG to
be cleared. Add lockdep annotation to dm_suspend() and dm_resume().
The existing DM_SUSPEND_FLAG remains unchanged.
DM_INTERNAL_SUSPEND_FLAG is set by dm_internal_suspend_noflush() and
cleared by dm_internal_resume().
Both DM_SUSPEND_FLAG and DM_INTERNAL_SUSPEND_FLAG may be set if a device
was already suspended when dm_internal_suspend_noflush() was called --
this can be thought of as a "nested suspend". A "nested suspend" can
occur with legacy userspace dm-thin code that might suspend all active
thin volumes before suspending the pool for resize.
But otherwise, in the normal dm-thin-pool suspend case moving forward:
the thin-pool will have DM_SUSPEND_FLAG set and all active thins from
that thin-pool will have DM_INTERNAL_SUSPEND_FLAG set.
Also add DM_INTERNAL_SUSPEND_FLAG to status report. This new
DM_INTERNAL_SUSPEND_FLAG state is being reported to assist with
debugging (e.g. 'dmsetup info' will report an internally suspended
device accordingly).

The WMI buffer can contain multiple events. First value in buffer is
length of event followed by data of specified length. After that is next
length and next data. When length is zero then there is no more events
in bufffer.
This patch adds support for processing all events in buffer (not only
first) and parse more event types (not only hotkey events). Because of
variable length of events sometimes BIOS fills more hotkeys (or other
values) into single WMI event. In this case this patch also processes
these multiple hotkeys (and not only first one).
Some event types are just ignored because kernel is not interested in
them (e.g. NIC Link status, battery unplug, ...).
This patch is based on DSDT table from Dell Latitude E6440. Code should
be backward compatible so will process other events of old types same as
before this patch.
This patch also fixes a problem with unknown WMI event messages being
written to the log. Now all known events are parsed and those which are
not interesting to the kernel are dropped without an unknown WMI event
message.

which performs the canonical address checks. On the case of assigning an EIP >=

When segment is accessed, real hardware does not perform any privilege level
checks. In contrast, KVM emulator does. This causes some discrepencies from
real hardware. For instance, reading from readable code segment may fail due to
incorrect segment checks. In addition, it introduces unnecassary overhead.
To reference Intel SDM 5.5 ("Privilege Levels"): "Privilege levels are checked
when the segment selector of a segment descriptor is loaded into a segment
register." The SDM never mentions privilege level checks during memory access,
except for loading far pointers in section 5.10 ("Pointer Validation"). Those
are actually segment selector loads and are emulated in the similarily (i.e.,
regardless to __linearize checks).
This behavior was also checked using sysexit. A data-segment whose DPL=0 was
loaded, and after sysexit (CPL=3) it is still accessible.
Therefore, all the privilege level checks in __linearize are removed.

When performing segmented-read/write in the emulator for stack operations, it
ignores the stack size, and uses the ad_bytes as indication for the pointer
size. As a result, a wrong address may be accessed.
To fix this behavior, we can remove the masking of address in __linearize and
perform it beforehand. It is already done for the operands (so currently it is
inefficiently done twice). It is missing in two cases:
1. When using rip_relative
2. On fetch_bit_operand that changes the address.
This patch masks the address on these two occassions, and removes the masking
from __linearize.
Note that it does not mask EIP during fetch. In protected/legacy mode code
fetch when RIP >= 2^32 should result in #GP and not wrap-around. Since we make
limit checks within __linearize, this is the expected behavior.
