The upstream Makefile uses DEBUG to control both stripping of debug
information *and* disabling optimisations.
We want to disable stripping of debug information so that (normally)
dh_strip can move it into a separate package later. However we also
want to enable optimisations by default.
Therefore:
- Set the STRIP variable (a command prefix) to "true"
- Set the DEBUG variable (a pseudo-boolean) to "true" if and only if
the "noopt" build option is used
These two are terse by default and don't respect the KBUILD_VERBOSE
environment variable.
(I considered adding V=1 to the MAKEFLAGS we use by default in
debian/rules.real, but this might have different semantics for the few
tools that aren't built using either kbuild or automake.)
This adds support for PREEMPT_RT by adding two new featureset: none and
rt. For now the rt featureset supports armmp only, support for lpae
might be added later. the none featureset supports both flavours armmp
and armmp-lpae.

Merge tag 'debian/4.17.6-2'
Release linux (4.17.6-2).
- Drop the ABI maintenance patch
- Resolve conflict between changes to config file generation in sid
(delete CONFIG_BUILD_SALT) and master (putting them in
arch-dependent packages)
Closes: #872263
- kbuild: Add build salt to the kernel and modules
- [arm64,powerpc,x86] Add build salt to the vDSO
- Set BUILD_SALT equal to the release string
The previous fix ensured that objtool was built for the right host
architecture, but it was still including some UAPI header files
(in particular <asm/bitsperlong.h>) for the build architecture.
Currently we replicate the mapping of Debian architectures to kernel
source architectures here. Use the KERNEL_ARCH variable that is now
passed down by rules.real. We still need to check whether perf is
supported on the architecture, though.

Merge tag 'debian/4.17.6-1'
Release linux (4.17.6-1).
- Drop patches for ABI maintenance or that are already upstream
- Drop ABI reference files
- Introduce linux-bootwrapper-<abiname> package containing boot wrapper
tools for the host architecture
- linux-image: Install symlinks to boot wrapper tools instead of the
native tools built by kbuild
This updates the debian changelog for listing changes of this stable
update. It also removes the patches that have been merged upstream.

objtool is normally built and used during the kernel build process,
in which case it should always be built as a native executable.
But when we build it for linux-tools it should match the target
architecture. We need to override the CC and LD variables to
make this work.
For parallel display outputs like RGB panels on i.MX device
DRM_IMX_PARALLEL_DISPLAY needs to be enabled

In Linux 4.18, various compiler version and feature tests are invoked
via kconfig rather than via kbuild. This means that we generally
cannot generate kconfig files for foreign architectures.
Move the config files to a new linux-config-<version> package which is
arch-dependent (and also M-A: same).
Make linux-config-<version> and linux-source-<version> recommend each
other.
We generate all config files when building linux-source-<version>,
and this requires running kconfig. kconfig is now built using
bison and flex instead of requiring their output to be already
included in the source tree.
- Various config symbols were removed, renamed or split
- HOTPLUG_PCI_SHPC is now boolean, so set it to built-in
- The stack protector config symbols were changed to two booleans
with different names
AM35x use EDMA for McASP audio SoC, resulting in a "missing
SND_EDMA_SOC" message during probe. This enables the support.

We always used to match arbitrary revision suffixes, but in commit
f4dbf1aa82 ".../debian.py: Fix binNMU revision parsing" I excluded
'+' from the revision_other to ensure that it wouldn't match a
binNMU suffix (which is matched separately).
Stop excluding '+' from the revision_other group, and change the
repetition to non-greedy so that any binNMU suffix will still match
the following group.
