atomisp: do not do full release if more video pipes are on use

The bug (TZSP-3288) is more or less easily reproducible on systems with
udev-like software. The helper (v4l_id) is run in parallel for all /dev/videoX
nodes twice with only purpose of checking capabilities:

 ->open("/dev/videoX")
 ->ioctl(VIDIOC_QUERYCAP)
 ->release("/dev/videoX")

case of 1st opened node it does full (stage 1 + stage 2) init. Otherwise it is
a fast path (stage 1 only).

However, atomisp_release() does a fast path for non-main pipes as well. This
triggers the unbalanced power management calls:

 ->open
   -> stage 1
     -> stage 2
       -> pm_runtime_get_sync
 ->release
   -> stage 1
     -> is_main? -> (no) -> fast path

Smack: allow for significantly longer Smack labels v4

V4 updated to current linux-security#next
Targeted for git://gitorious.org/smack-next/kernel.git

Modern application runtime environments like to use
naming schemes that are structured and generated without
human intervention. Even though the Smack limit of 23
characters for a label name is perfectly rational for
human use there have been complaints that the limit is
a problem in environments where names are composed from
a set or sources, including vendor, author, distribution
channel and application name. Names like

softwarehouse-pgwodehouse-coolappstore-mellowmuskrats

are becoming harder to avoid. This patch introduces long
label support in Smack. Labels are now limited to 255
characters instead of the old 23.

The primary reason for limiting the labels to 23 characters
was so they could be directly contained in CIPSO category sets.
This is still done were possible, but for labels that are too
large a mapping is required. This is perfectly safe for communication
that stays "on the box" and doesn't require much coordination
between boxes beyond what would have been required to keep label
names consistent.

The bulk of this patch is in smackfs, adding and updating
administrative interfaces. Because existing APIs can't be
changed new ones that do much the same things as old ones
have been introduced.

The Smack specific CIPSO data representation has been removed
and replaced with the data format used by netlabel. The CIPSO
header is now computed when a label is imported rather than
on use. This results in improved IP performance. The smack
label is now allocated separately from the containing structure,
allowing for larger strings.

Four new /smack interfaces have been introduced as four
of the old interfaces strictly required labels be specified
in fixed length arrays.

The access interface is supplemented with the check interface:
access  "Subject                 Object                  rwxat"
access2 "Subject Object rwaxt"

The load interface is supplemented with the rules interface:
load   "Subject                 Object                  rwxat"
load2  "Subject Object rwaxt"

The load-self interface is supplemented with the self-rules interface:
load-self   "Subject                 Object                  rwxat"
load-self2  "Subject Object rwaxt"

The cipso interface is supplemented with the wire interface:
cipso  "Subject                  lvl cnt  c1  c2 ..."
cipso2 "Subject lvl cnt  c1  c2 ..."

The old interfaces are maintained for compatibility.

gfx: a better way to do gfx suspend/resume at DPMS on/off

A regression was introduced since we add gfx runtime pm support in DPMS
control interface and the "-sharevts" parameter for X launch on mfld, if
user run "xset dpms force off" and then "echo mem > /sys/power/state",
dsi dpi panel will fail to resume back.

Here is the problem analysis: at DPMS off, gfx driver will shutdown the
panel and enter runtime suspend, at this time if kernel doing system suspend,
PCI subsystem will call device's runtime resume interface if it find
device is in runtime suspend state. In this case it just resume gfx device
but doesn't handle dsi dpi panel, then it will cause panel fail to light on in
subsequent resume path.

The fix is directly calling  functions to control gfx device suspend/resume,
rather than the indirect way of pm_runtime_put() and pm_runtime_get().

netlink: advertise incomplete dumps

Consider the following situation:
 * a dump that would show 8 entries, four in the first
   round, and four in the second
 * between the first and second rounds, 6 entries are
   removed
 * now the second round will not show any entry, and
   even if there is a sequence/generation counter the
   application will not know

To solve this problem, add a new flag NLM_F_DUMP_INTR
to the netlink header that indicates the dump wasn't
consistent, this flag can also be set on the MSG_DONE
message that terminates the dump, and as such above
situation can be detected.

To achieve this, add a sequence counter to the netlink
callback struct. Of course, netlink code still needs
to use this new functionality. The correct way to do
that is to always set cb->seq when a dumpit callback
is invoked and call nl_dump_check_consistent() for
each new message. The core code will also call this
function for the final MSG_DONE message.
