When the function tipc_group_filter_msg() finds that a member event
indicates that the member is leaving the group, it first deletes the
member instance, and then purges the message queue being handled
by the call. But the message queue is an aggregated field in the
just deleted item, leading the purge call to access freed memory.
We fix this by swapping the order of the two actions.

On some systems, when we unsplit a port we need to re-create two ports
instead. On other systems, only one needs to be re-created.
Do not try to create a port if during driver initialization it was
assigned a negative module number, which is invalid.
This avoids the following error during unsplit:
[ 941.012478] mlxsw_spectrum 0000:01:00.0: Port 43: Failed to map module
The error is harmless and caused by the fact that a local port is
already mapped to module 0.

Profiles that have an undecidable overlap in their attachments are
being incorrectly handled. Instead of failing to attach the first one
encountered is being used.
eg.
profile A /** { .. }
profile B /*foo { .. }
have an unresolvable longest left attachment, they both have an exact
match on / and then have an overlapping expression that has no clear
winner.
Currently the winner will be the profile that is loaded first which
can result in non-deterministic behavior. Instead in this situation
the exec should fail.

gcc-4.4 points out suspicious code in compute_mnt_perms, where
the aa_perms structure is only partially initialized before getting
returned:
security/apparmor/mount.c: In function 'compute_mnt_perms':
security/apparmor/mount.c:227: error: 'perms.prompt' is used uninitialized in this function
security/apparmor/mount.c:227: error: 'perms.hide' is used uninitialized in this function
security/apparmor/mount.c:227: error: 'perms.cond' is used uninitialized in this function

security/apparmor/mount.c:227: error: 'perms.stop' is used uninitialized in this function
security/apparmor/mount.c:227: error: 'perms.deny' is used uninitialized in this function
Returning or assigning partially initialized structures is a bit tricky,
in particular it is explicitly allowed in c99 to assign a partially
initialized structure to another, as long as only members are read that
have been initialized earlier. Looking at what various compilers do here,
the version that produced the warning copied uninitialized stack data,
while newer versions (and also clang) either set the other members to
zero or don't update the parts of the return buffer that are not modified
in the temporary structure, but they never warn about this.
In case of apparmor, it seems better to be a little safer and always
initialize the aa_perms structure. Most users already do that, this
changes the remaining ones, including the one instance that I got the
warning for.

Print a rate-limited warning when a user-space program attempts to execute
any of the instructions that UMIP protects (i.e., SGDT, SIDT, SLDT, STR
and SMSW).
This is useful, because when CONFIG_X86_INTEL_UMIP=y is selected and
supported by the hardware, user space programs that try to execute such
instructions will receive a SIGSEGV signal that they might not expect.
In the specific cases for which emulation is provided (instructions SGDT,
SIDT and SMSW in protected and virtual-8086 modes), no signal is
generated. However, a warning is helpful to encourage updates in such
programs to avoid the use of such instructions.
Warnings are printed via a customized printk() function that also provides
information about the program that attempted to use the affected
instructions.
Utility macros are defined to wrap umip_printk() for the error and warning
kernel log levels.
While here, replace an existing call to the generic rate-limited pr_err()
with the new umip_pr_err().

Currently device-bound programs are not able to run on the host
to save resources (host JIT is not invoked). Don't allow XDP
programs to be attached without the HW_MODE flag. In theory
if program is already translated for device offload the driver
should choose to offload it instead of loading it in the driver.
However, offloading translated program may still fail resulting
in device-bound program being run on the host.
Prevent this by refusing to attach device bound programs if

With TC shared block changes we can't depend on correct netdev
pointer being available in cls_bpf. Move the device validation
to the driver. Core will only make sure that offloaded programs
are always attached in the driver (or in HW by the driver). We
trust that drivers which implement offload callbacks will perform
necessary checks.
Moving the checks to the driver is generally a useful thing,
in practice the check should be against a switchdev instance,
not a netdev, given that most ASICs will probably allow using
the same program on many ports.

platform without this fix, disable the userspace interface.
A hotfix indicator is present in the dell-wmi-descriptor that represents
whether or not more complex calls will work properly.
"Simple" calls such as those used by dell-laptop and dell-wmi will continue
to work properly so dell-smbios-wmi should not be blocked from binding and
being used as the dell-smbios dispatcher.

Implement a '-none' output mode for kernel-doc which will only output
warning messages, and suppresses the warning message about there being
no kernel-doc in the file.
If the build has requested additional warnings, automatically check all
.c files. This patch does not check .h files. Enabling the warning
by default would add about 1300 warnings, so it's default off for now.
People who care can use this to check they didn't break the docs and
maybe we'll get all the warnings fixed and be able to enable this check
by default in the future.

It isn't clear if this function of_node_put()s the 'from'
argument, or the node it searches. Clearly indicate which
variable is touched. Fold in some more fixes from Randy too
because we're in the area.

Drop CONFIG_VIDEO_400_HACK info completely.
Drop CONFIG_VIDEO_RETAIN and CONFIG_VIDEO_LOCAL completely.
Drop CONFIG_VIDEO_COMPACT and CONFIG_VIDEO_VESA info completely.
Drop CONFIG_VIDEO_SVGA info since it has been removed.
Drop chapter number & section number references since they are wrong.
Drop (bad) ftp URL for 800x600 Thinkpad XF86Config.
Rename CONFIG_VIDEO_GFX_HACK to VIDEO_GFX_HACK since it is not a
Kconfig symbol. And to match the source code.
Build options are controlled by the kernel kconfig utility.

Sometimes a single patch is the result of multiple authors. As git only
can have one "author" of a patch, it is still good to properly give
credit to the other developers of a commit. To address this, document
the "Co-Developed-by:" tag which can be used to show other authors of
the patch.
Note, these other authors must also provide a Signed-off-by: tag as it
is their work that is being submitted here.
