Introduce the configuration variable KERNEL_NAME, typically to be
defined by the machine, that selected the kernel that is installed and
can also be depended on / built against.
Create a shadow recipe linux-disto.bb that simply PROVIDES to the
bitbake world distro kernel targets that exist in package form in either
Debian or Raspian.

With this include, it becomes almost trivial to replace the distro
kernel with a custom build. You just need to include linux-custom.inc,
specify the source URI, define via S where the source is unpacked to and
provide a defconfig.
To switch to a custom kernel recipe, KERNEL_NAME has to be adjusted in
local.conf or the machine configuration.
Unless explicitly stated via KERNEL_FLAVOR, this tag is derived from
the including recipe name which then needs to follow the scheme
"linux-<flavor>[_version].bb".
The different kernel defconfig file name can be specified via the
KERNEL_DEFCONFIG variable so that also machine-specific defconfigs can
be set in the same recipe (KERNEL_DEFCONFIG_my-machine = "...").
The approach works internally by first running "make deb-pkg" on the
kernel and the repackages the output to make the binary linux-image and
linux-header debs act as proper replacement of a distro kernel. This
results in a suboptimal technical implementation which may eventually be
replaced by an isar-implemented deb-pkg build process. However, this is
not expected to affect the user-visible interface of this class.

From: Jan Kiszka <jan.kiszka@siemens.com>
Provide two examples for describing custom kernel builds. Both are for
x86_64, simply using upstream x86_64_defconfig to define the required
defconfig. One example is demoing a build from a tarball, the other
pulling from git.

This provides an include for custom kernel modules. We choose an include
over a class as we carry a couple of files to debianize the module. The
user just needs to specify the module SRC_URI, and those sources must be
then reside in a separate directory which is - as usual - defined via S.

This demonstrates the usage of the new module.inc via a primitive
hello world module.
For wheezy:vexpress, module builds unfortunately fail with
/usr/bin/ld: unrecognized option '-Wl,-z,relro'
So disable the example on in the related multiconfig.

This provides an include for custom kernel modules. We choose an include
over a class as we carry a couple of files to debianize the module. The
user just needs to specify the module SRC_URI, and those sources must be
then reside in a separate directory which is - as usual - defined via S.

Changes in v6:
- fix module build on wheezy-arm and (upcoming) stretch-arm64
This allows to keep v5 of patch 5. Sorry for the mess, but I initially
thought it was an issue with old wheezy on special ARM hardware only.
But when it also popped up on stretch-arm64, I finally analyzed it.

Looks good to me, applied to next. Should I wait documentation for this
feature?
One small issue: you use @XYZ@ pattern for substitution, while ##XYZ##
is used in multistrap configs. I'm with unified style in Isar. I'd
prefer your variant, so just as TODO for somebody - replace remaining
##XYZ## patterns in Isar to @XYZ@.

If the multistrap cases will go anyway, this consolidation would come
for free.

Ouch, didn't notice this. :-(
Do you have any specific reason to have module_init failed? Could we
have zero return code to test its probe-ability and loading-by-default
for CI?

I didn't think of CI for this module yet, but that may make more sense
then. Do you plan to write some CI script for that? Then just change the
module code to your needs. It's "just an example". :)

Ok, thanks!
Now there is simple automated which checks that each virtual machine has
reached login prompt. You could see this in the bottom of console output:
http://isar-build.org:8080/job/isar_next/105/console
To be honest, I don't want to check this manually after each merge, so
I'm thinking about test automation for everything new appears in Isar :-)
