Allow recipes to specify sections to be stripped from the kernel output
using KERNEL_IMAGE_STRIP_EXTRA_SECTIONS. For example:
KERNEL_IMAGE_STRIP_EXTRA_SECTIONS = ".comment .unwanted"
The kernel output is stripped in place.
Since the toolchain does not give indication when the specified sections
are absent, we read the sections first and make this report by issuing a
warning to the developer.
The toolchain by default strips the image with the -s option (even
when -s is not specified):
-s --strip-all Remove all symbol and relocation information
For example, these sections are always removed:
.debug_aranges
.debug_info
.debug_abbrev
.debug_line
.debug_frame
.debug_str
.debug_loc
.debug_ranges
.symtab
.strtab
In addition to these, the sections listed in
KERNEL_IMAGE_STRIP_EXTRA_SECTIONS will also be removed.
Only stripping of vmlinux (elf) is supported at this time. A warning
will be given if the image type is not vmlinux.
Stripping the image could also be done in the kernel, but that would
only work for linux-yocto based kernels, so it's not the route we
decided to go.

Variables defined in .scc files have two purposes:
- Documentation in the meta-series
- Variables that can be tested in sub sections and other features
The second part of this functionality was broken when fixing configuration
for tiny/small systems. As a result, arch tests were failing and configs were
dropped. This restores the existing functionality.

This is fixed by:

And by disabling ftrace for qemumips boards
2) netfilter options being dropped
When KERNEL_EXTRA_FEATURES was introduced, and allowed to be
inhibited, the variable was only applied to qemux86 machines. It
should be applied ot all machine types (unless inhibited), so we

One of the features introduced early on in the 1.4 release cycle was the
ability to include a kernel feature, but only get its patches and not configs
(and vice versa).
As it turns out, this only was exercised recently and once a single include
with dropped configs was started, ALL configuration values following the
commit were dropped.
To fix the problem, the processing of kernel features has been split into
two. Where the features are preprocessed and the assembled/complete file is
used to generate the meta-series (which is later applied to the tree). The
logic of the tools is the same, but the two phases of processing allows
configuration values to be excluded properly and simply, while keeping the
logic for modifying the tree in a separate step.
All changes are invisible to the user, and are done within the existing
scripts and build system bindings. Output series and manipulations to
the tree are the same as they were before this change.
Updating the kern-tools SRCREV to pickup the kern-tools changes for this.

The policy of building AUTOFS as a module is something that can be
changed, since boot processes that use automounting can take advantage
of the built in support to reduce complexity.
The size increase of the base policy is small with this change, and
users of the linux-yocto kernel can still override this value, which
is exactly what the poky-tiny kernel does.
Keeping the configuration consistent for all boards, and not adding
and exception for qemumips makes sense in this case.

Not only was the variable reference in this line broken, but it wasn't
going to work anyway - we install the script directly into /etc/rcS.d
and not into /etc/init.d, so the code in update-rc.d.bbclass couldn't
find anything there. This resulted in a postinstall script for
rpm-postinsts being created in /etc/rpm-postinsts which can't work when
the root filesystem is read-only. To simplify things just remove the use
of update-rc.d.bbclass since we don't really need the added complexity
here.
