Introduce the 3.10 kernel. This is based on the 3.10.9 upstream kernel
and replaces the 3.8 recipes, which will be removed once all reference
boards have been updated.
3.10 also the latest LTSI and will be updated with that content when it
becomes available.
Other features of the 3.10 kernel include:
- refreshed -rt support
- refreshed yaffs2, aufs3
- cryptodev
- bfs, edf, and OCF staged features
- scrubbed and updated meta data for v3.10
- improved tools support for meta data updates and queue maintenance
- patch carry forward from all previous linux-yocto kernels and
configuration.
This kernel has been built and boot tested on all qemu machines and architectures.

The addition of ptrace_peeksiginfo_args to the uapi in kernel commit

These are bug fixes, usability changes as well as the removal of the
guilt dependency. During the uprev of the guilt package, the amount of
circumvention of the typical guilt workflow and checks meant that using
it as a series -> branch manager was no longer appropriate. As a result
a new tools kgit-s2q (series 2 queue) was created based on git-quiltimport,
git am, and the LTSI tree generation scripts.
The result is better series to branch validation, faster application and
a simpler management model. This tool is backwards compatible with any
tree previously constructed with guilt. We are now "guilt free"

As the Linux kernel, unconditionally, builds the dtc application and
it is the compatible version with the DeviceTree files shipped within
the kernel it is better to use it and the kernel build system to
generate the dtb files.
Some DeviceTree files rely on CPP and kernel headers to be able to
generate the dtb binary contents and it is harder to replicate it
outside of Linux kernel build system so we /use/ it.
To comply with these assumptions we need to use the dtb file when
calling 'make' instead of pointing to the DeviceTree source file; the
code has been made backward compatible but it is advised to move to
the new definition to avoid warnings as:
,----[ Original definition ]
| KERNEL_DEVICETREE = "${S}/arch/arm/boot/dts/imx6q-sabresd.dts"
`----
Becomes:
,----[ New definition ]
| KERNEL_DEVICETREE = "imx6q-sabresd.dtb"

It was pointed out that the current way the KERNEL_FEATURES variable
is appended in the base linux-yocto recipe doesn't allow the appended
features to be prevented in a layer without using python code and
a recipe finalize hook.
To allow easier overriding of 'extra' or 'optional' features that are
defined in the linux-yocto recipe, we create a KERNEL_EXTRA_FEATURES
variable. This variable can be set in a layer to define extra features
or cleared to prevent the recipe's extra features from being appended
to the core functionality.

tracing_enabled should not be used, it is heavy weight and does not
do much in helping lower the overhead. see commmit (Deprecate
tracing_enabled for tracing_on 6752ab4a9c30d5411b2dfdb251a3f1cb18aae48)

Moving forward we plan to support two kernels plus the development

for this version will be carried in the sustained/old releases.
