Denis Efremov 512ddf7d7d coccicheck: return proper error code on fail
If coccicheck fails, it should return an error code distinct from zero
to signal about an internal problem. Current code instead of exiting with
the tool's error code returns the error code of 'echo "coccicheck failed"'
which is almost always equals to zero, thus failing the original intention
of alerting about a problem. This patch fixes the code.

Found by Linux Driver Verification project (linuxtesting.org).

Julia Lawall 09d4d9648b Coccinelle: doubletest: reduce side effect false positives
Ensure that the cited expression is not a function call or an
assignment to reduce the chance of false positives.

Slightly modify the warning message to indicate another source
of false positves.

Masahiro Yamada d6c6ab93e1 kbuild: remove deprecated host-progs variable
The host-progs has been kept as an alias of hostprogs-y for a long time
(at least since the beginning of Git era), with the clear prompt:
  Usage of host-progs is deprecated. Please replace with hostprogs-y!

Enough time for the migration has passed.

Ben Hutchings 79a85b55e3 builddeb: Add automatic support for sh{3,4}{,eb} architectures
Different generations of the SH architecture are not very compatible,
so there are/were separate Debian ports for SH3 and SH4.

Move the fallback out of the "case" statement, so that it will also be
used in case we find some SH architecture version without a known
mapping.

Ben Hutchings 75ebcee769 builddeb: Add automatic support for riscv* architectures
Debian currently only defines "riscv64", but it seems safe to assume
that any 32-bit port will now be called "riscv32", also matching
$UTS_MACHINE.

Ben Hutchings a27ae285d5 builddeb: Add automatic support for sparc64 architecture
We currently label 64-bit kernel packages as sparc (32-bit), mostly
because it was officially supported while sparc64 was not.  Now
neither is officially supported, so label these packages as sparc64.

We currently label 64-bit big-endian kernel packages as
powerpc (32-bit), mostly because it was officially supported while
ppc64 (64-bit big-endian) was not.  Now neither is officially

Debian also has a powerpcspe (32-bit with SPE) architecture.
Label packages with a suitable configuration as powerpcspe.

Ben Hutchings 091d30aefc builddeb: Change architecture detection fallback to use dpkg-architecture
We currently use dpkg --print-architecture, which reports the
architecture of the build machine.  We can make a better guess
than this by asking dpkg-architecture what the host architecture,
i.e. the default architecture for building packages, is.  This is
sensitive to environment variables such as CC and DEB_HOST_ARCH,
which should already be set in a cross-build environment.

Masahiro Yamada 43fee2b238 kbuild: do not redirect the first prerequisite for filechk
Currently, filechk unconditionally opens the first prerequisite and
redirects it as the stdin of a filechk_* rule.  Hence, every target
using $(call filechk,...) must list something as the first prerequisite
even if it is unneeded.

'< $<' is actually unneeded in most cases.  Each rule can explicitly
adds it if necessary.
