1ec0ed0839 [media] v4l: Remove "_ACTUAL" from subdev selection API target definition names
The string "_ACTUAL" does not say anything more about the target names. Drop
it. V4L2 selection API was changed by "V4L: Remove "_ACTIVE" from the
selection target name definitions" by Sylwester Nawrocki. This patch does
the same for the V4L2 subdev API.

c133482300 [media] V4L: Remove "_ACTIVE" from the selection target name definitions
This patch drops the _ACTIVE part from the selection target names
as a prerequisite to unify the selection target names across the subdev
and regular video node API.

The meaning of V4L2_SEL_TGT_*_ACTIVE and V4L2_SUBDEV_SEL_TGT_*_ACTUAL
selection targets is logically the same. Different names add to confusion
where both APIs are used in a single driver or an application. For some
system configurations different names may lead to interoperability issues.

For backwards compatibility V4L2_SEL_TGT_CROP_ACTIVE and
V4L2_SEL_TGT_COMPOSE_ACTIVE are defined as aliases to V4L2_SEL_TGT_CROP
and V4L2_SEL_TGT_COMPOSE. These aliases will be removed after deprecation
period, according to Documentation/feature-removal-schedule.txt.

Tested with an actual Connectix B&W parallel port webcam, both on a

6016af82ea [media] v4l2: use __u32 rather than enums in ioctl() structs
V4L2 uses the enum type in IOCTL arguments in IOCTLs that were defined until
the use of enum was considered less than ideal. Recently Rémi Denis-Courmont
brought up the issue by proposing a patch to convert the enums to unsigned:

<URL:http://www.spinics.net/lists/linux-media/msg46167.html>

This sparked a long discussion where another solution to the issue was
proposed: two sets of IOCTL structures, one with __u32 and the other with
enums, and conversion code between the two:

<URL:http://www.spinics.net/lists/linux-media/msg47168.html>

Both approaches implement a complete solution that resolves the problem. The
first one is simple but requires assuming enums and __u32 are the same in
size (so we won't break the ABI) while the second one is more complex and
less clean but does not require making that assumption.

The issue boils down to whether enums are fundamentally different from __u32
or not, and can the former be substituted by the latter. During the
discussion it was concluded that the __u32 has the same size as enums on all
archs Linux is supported: it has not been shown that replacing those enums
in IOCTL arguments would break neither source or binary compatibility. If no
such reason is found, just replacing the enums with __u32s is the way to go.

This is what this patch does. This patch is slightly different from Remi's
first RFC (link above): it uses __u32 instead of unsigned and also changes
the arguments of VIDIOC_G_PRIORITY and VIDIOC_S_PRIORITY.

b1a808ff43 Merge branch 'for-next' of git://gitorious.org/kernel-hsi/kernel-hsi
Pull HSI (High Speed Synchronous Serial Interface) framework from Carlos Chinea:
 "The High Speed Synchronous Serial Interface (HSI) is a serial
  interface mainly used for connecting application engines (APE) with
  cellular modem engines (CMT) in cellular handsets.

  The framework is currently being used for some people and we would
  like to see it integrated into the kernel for 3.3.  There is no HW
  controller drivers in this pull, but some people have already some of
  them pending which they would like to push as soon as this integrated.
  I am also working on the acceptance for an TI OMAP one, based on a
  compatible legacy version of the interface called SSI."

Ok, so it didn't get into 3.3, but here it is pulled into 3.4.

Several people piped up to say "yeah, we want this".

bec4d62ead kgdb,debug_core: add the ability to control the reboot notifier
Sometimes it is desirable to stop the kernel debugger before allowing
a system to reboot either with kdb or kgdb.  This patch adds the
ability to turn the reboot notifier on and off or enter the debugger
and stop kernel execution before rebooting.

It is possible to change the setting after booting the kernel with the
following:

echo 1 > /sys/module/debug_core/parameters/kgdbreboot

It is also possible to change this setting using kdb / kgdb to
manipulate the variable directly.

Using KDB:
   mm kgdbreboot 1

Using gdb:
   set kgdbreboot=1
