Using memcpy() from a string that is shorter than the length copied means
the destination buffer is being filled with arbitrary data from the kernel
rodata segment. Instead, use strncpy() which will fill the trailing bytes
with zeros.
This was found with the future CONFIG_FORTIFY_SOURCE feature.

For configurations that do not enable DAX filesystems or drivers, do not
require the DAX core to be built.
Given that the 'direct_access' method has been removed from
'block_device_operations', we can also go ahead and remove the
block-related dax helper functions from fs/block_dev.c to
drivers/dax/super.c. This keeps dax details out of the block layer and
lets the DAX core be built as a module in the FS_DAX=n case.
Filesystems need to include dax.h to call bdev_dax_supported().

If adapter is in "down" state we still allow user to see statistics from HW.

Some connectors may not allow all scaling mode properties, this function will allow
creating the scaling mode property with only the supported subset. It also wires up
this state for atomic.
This will make it possible to convert i915 connectors to atomic.
Changes since v1:
- Add DRM_MODE_PROP_ENUM flag to drm_property_create
- Use the correct index in drm_property_add_enum.
- Add DocBook for function (Sean Paul).
- Warn if less than 2 valid scaling modes are passed.
- Remove level of indent. (Sean Paul)

With gcc 4.1.2:
drivers/nvme/host/lightnvm.c: In function ‘nvme_nvm_submit_io’:
drivers/nvme/host/lightnvm.c:498: warning: ‘rq’ is used uninitialized in this function
Indeed, since commit 2e13f33a2464fc3a ("lightnvm: create cmd before
allocating request"), the request is passed to nvme_nvm_rqtocmd() before
it is allocated.
Fortunately, as of commit 91276162de9476b8 ("lightnvm: refactor end_io
functions for sync"), nvme_nvm_rqtocmd () no longer uses the passed
request, so this warning is a false positive.
Drop the unused parameter to clean up the code and kill the warning.

Let the target core check the CMD_T_ABORTED flag instead of the SRP
target driver. Hence remove the transport_check_aborted_status()
call. Since state == SRPT_STATE_CMD_RSP_SENT is something that really
should not happen, do not try to recover if srpt_queue_response() is
called for an I/O context that is in that state. This patch is a bug
fix because the srpt_abort_cmd() call is misplaced - if that function
is called from srpt_queue_response() it should either be called
before the command state is changed or after the response has been
sent.

There are some similar devices in the existing device table where this

The driver is sending a response to the actual scsi op that was
aborted by an abort task TM, while LIO is sending a response to
the abort task TM.
ibmvscsis_tgt does not send the response to the client until
release_cmd time. The reason for this was because if we did it
at queue_status time, then the client would be free to reuse the
tag for that command, but we're still using the tag until the
command is released at release_cmd time, so we chose to delay
sending the response until then. That then caused this issue, because
release_cmd is always called, even if queue_status is not.
SCSI spec says that the initiator that sends the abort task
TM NEVER gets a response to the aborted op and with the current
code it will send a response. Thus this fix will remove that response
if the CMD_T_ABORTED && !CMD_T_TAS.
Another case with a small timing window is the case where if LIO sends a
TMR_DOES_NOT_EXIST, and the release_cmd callback is called for the TMR Abort
cmd before the release_cmd for the (attemped) aborted cmd, then we need to
ensure that we send the response for the (attempted) abort cmd to the client
before we send the response for the TMR Abort cmd.

git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull libnvdimm updates from Dan Williams:
"The bulk of this has been in multiple -next releases. There were a few
late breaking fixes and small features that got added in the last
couple days, but the whole set has received a build success
notification from the kbuild robot.
Change summary:
- Region media error reporting: A libnvdimm region device is the
parent to one or more namespaces. To date, media errors have been
reported via the "badblocks" attribute attached to pmem block
devices for namespaces in "raw" or "memory" mode. Given that
namespaces can be in "device-dax" or "btt-sector" mode this new
interface reports media errors generically, i.e. independent of
namespace modes or state.
This subsequently allows userspace tooling to craft "ACPI 6.1
Section 9.20.7.6 Function Index 4 - Clear Uncorrectable Error"
requests and submit them via the ioctl path for NVDIMM root bus
devices.
- Introduce 'struct dax_device' and 'struct dax_operations': Prompted
by a request from Linus and feedback from Christoph this allows for
dax capable drivers to publish their own custom dax operations.
This fixes the broken assumption that all dax operations are
related to a persistent memory device, and makes it easier for
other architectures and platforms to add customized persistent
memory support.
- 'libnvdimm' core updates: A new "deep_flush" sysfs attribute is
available for storage appliance applications to manually trigger
memory controllers to drain write-pending buffers that would
otherwise be flushed automatically by the platform ADR
(asynchronous-DRAM-refresh) mechanism at a power loss event.
Support for "locked" DIMMs is included to prevent namespaces from
surfacing when the namespace label data area is locked. Finally,
fixes for various reported deadlocks and crashes, also tagged for
-stable.
- ACPI / nfit driver updates: General updates of the nfit driver to
add DSM command overrides, ACPI 6.1 health state flags support, DSM
payload debug available by default, and various fixes.

alpha:allmodconfig fails to build as follows.
drivers/gpu/drm/amd/amdgpu/amdgpu.h:1006:2: error:
expected identifier before '(' token
drivers/gpu/drm/amd/amdgpu/amdgpu.h:1011:28: error:
'NGG_BUF_MAX' undeclared here
The problem is not really the enum definition of NGG_BUF_MAX but PARAM,
which happens to be defined differently for alpha and a couple of other
architectures.
Use less generic defines for NGG enums to solve the problem.

The ACPI SCI (System Control Interrupt) is set up as a wakeup IRQ
during suspend-to-idle transitions and, consequently, any events
signaled through it wake up the system from that state. However,
on some systems some of the events signaled via the ACPI SCI while
suspended to idle should not cause the system to wake up. In fact,
quite often they should just be discarded.
Arguably, systems should not resume entirely on such events, but in
order to decide which events really should cause the system to resume
and which are spurious, it is necessary to resume up to the point
when ACPI SCIs are actually handled and processed, which is after
executing dpm_resume_noirq() in the system resume path.
For this reasons, add a loop around freeze_enter() in which the
platforms can process events signaled via multiplexed IRQ lines
like the ACPI SCI and add suspend-to-idle hooks that can be
used for this purpose to struct platform_freeze_ops.
In the ACPI case, the ->wake hook is used for checking if the SCI
has triggered while suspended and deferring the interrupt-induced
system wakeup until the events signaled through it are actually
processed sufficiently to decide whether or not the system should
resume. In turn, the ->sync hook allows all of the relevant event
queues to be flushed so as to prevent events from being missed due
to race conditions.
In addition to that, some ACPI code processing wakeup events needs
to be modified to use the "hard" version of wakeup triggers, so that
it will cause a system resume to happen on device-induced wakeup
events even if the "soft" mechanism to prevent the system from
suspending is not enabled (that also helps to catch device-induced
wakeup events occurring during suspend transitions in progress).
