f7a2c31f1e kbuild, deb-pkg: fix generated package name
The binary package that make deb-pkg creates is a linux-image.
To be fixed may also be the addition of $DEB_ARCH.

4bf4cd4939 kbuild, deb-pkg: improve Source field
The Source: field is defined as the source package in the package
archive from which a binary packages are built. As deb-pkg does not
generate a source package, we should avoid to use any existing source
packages here.

edec611db0 kbuild, deb-pkg: improve maintainer identification
Try harder to find email and maintainer name.
Debian's own devscripts all use DEBEMAIL or DEBFULLNAME prior to an
eventual EMAIL or NAME environment variable. Match their logic.

"Anonymous" sounds nicer then "Kernel Compiler" if no name is found.

4964451a32 kbuild, deb-pkg: pass Debian maintainer script parameters to packaging hook scripts
The Debian packaging scripts created by the deb-pkg target do not pass
on the standard Debian maintainer script parameters to hook scripts,
which means that those scripts cannot tell whether they are being called
during e.g. install vs. upgrade, or removal vs. purge of the package.

As there are several variantions in how hook scripts are called from
kernel packages, we pass the parameters in the environment variable
DEB_MAINT_PARAMS rather than as extra arguments.

Bump version of builddep script to 1.3.

d3dd3b5a29 kbuild: allow compressors (gzip, bzip2, lzma) to take multiple inputs
Allow the compression commands in Kbuild (i.e. gzip, bzip2, lzma) to
take multiple input files and emit the concatenated compressed
output.  This avoids an intermediate step when a kernel image is built
from multiple components, such as the relocatable x86-32 kernel.

Sam Ravnborg integrated the bin_size script into the Makefile.

31b6e76e21 ftrace: use .sched.text, not .text.sched in recordmcount.pl
The only references in the kernel to the .text.sched section are in
recordmcount.pl.  Since the code it has is intended to be example code
it should refer to real kernel sections.  So change it to .sched.text
instead.

4391ed6aa9 kbuild, modpost: fix unexpected non-allocatable warning with mips
mips emit the following debug sections:
.mdebug* and .pdr

They were included in the check for non-allocatable section
and caused modpost to warn.

Manuel Lauss suggested to fix this by adding the relevant
sections to the list of sections we do not check.

028ecebdd8 kbuild, modpost: fix "unexpected non-allocatable" warning with SUSE gcc
Jean reported that he saw one warning for each module like the one below:
WARNING: arch/x86/kernel/cpu/cpufreq/acpi-cpufreq.o (.comment.SUSE.OPTs): unexpected non-allocatable section.

The warning appeared with the improved version of the
check of the flags in the sections.

That check already ignored sections named ".comment" - but SUSE store
additional info in the comment section and has named it in a SUSE
specific way. Therefore modpost failed to ignore the section.

The fix is to extend the pattern so we ignore all sections
that start with the name ".comment.".

9fffb55f66 Move dtc and libfdt sources from arch/powerpc/boot to scripts/dtc
The powerpc kernel always requires an Open Firmware like device tree
to supply device information.  On systems without OF, this comes from
a flattened device tree blob.  This blob is usually generated by dtc,
a tool which compiles a text description of the device tree into the
flattened format used by the kernel.  Sometimes, the bootwrapper makes
small changes to the pre-compiled device tree blob (e.g. filling in
the size of RAM).  To do this it uses the libfdt library.

Because these are only used on powerpc, the code for both these tools
is included under arch/powerpc/boot (these were imported and are
periodically updated from the upstream dtc tree).

However, the microblaze architecture, currently being prepared for
merging to mainline also uses dtc to produce device tree blobs.  A few
other archs have also mentioned some interest in using dtc.
Therefore, this patch moves dtc and libfdt from arch/powerpc into
scripts, where it can be used by any architecture.

The vast bulk of this patch is a literal move, the rest is adjusting
the various Makefiles to use dtc and libfdt correctly from their new
locations.

surrounded by /* ...  */ <struct members> /* ...  */ if there is a /*

b614a697dc kbuild, modpost: Check the section flags, to catch missing "ax"/"aw"
When you put
  .section ".foo"
in an assembly file instead of
  .section "foo", "ax"
, one of the possible symptoms is that modpost will see an
ld-generated section name ".foo.1" in section_rel() or section_rela().
But this heuristic has two problems: it will miss a bad section that
has no relocations, and it will incorrectly flag many gcc-generated
sections as bad when compiling with -ffunction-sections
-fdata-sections.

On mips it fixes a lot of bogus warnings with gcc 4.4.0 lije this one:
WARNING: crypto/cryptd.o (.text.T.349): unexpected section name.

So instead of checking whether the section name matches a particular
pattern, we directly check for a missing SHF_ALLOC in the section
flags.
