99b2cdde83 scripts/extract-ikconfig: Support LZ4-compressed images.
Support for kernel image LZ4 compression was added around 3.11, but not
the corresponding kernel .config extraction.

This makes possible extracting the kernel config for LZ4-compressed
kernels you're not running, or the current LZ4-compressed kernel if
compiled without /proc/config.gz support.

7b76bfc867 kconfig: simplification of scripts/extract-ikconfig
I've rewritten the extract-ikconfig script to extract the kernel
configuration from a kernel compiled with CONFIG_IKCONFIG. The main
motivation for the rewrite was to remove the dependency on the
external C program binoffset.c, which is compiled on the initial run.

The binoffset executable is invoked with a relative path, which means
that the old script can only be run from the top of the kernel tree,
and only when you have write permission in the scripts directory.

The new script uses tr/grep/tail/zcat only, and can be invoked from
anywhere. The binoffset.c program has been removed. This script
requires GNU grep 2.5 (released 2002-03-13) or higher, because the -o
option was introduced in that version.

6be51ffc17 kconfig: have extract-ikconfig read ELF files
It would be nice to use extract-ikconfig to find the congfig.gz
in either vmlinux (not vmlinuz) or configs.ko.

This patch changes the script to also be able to read ELF files directly.

[ Impact: find config.gz in vmlinux and configs.ko ]

Both start and end should be tested for existence before continuing
to parse the config.gz file.

efddd79512 remove bashisms from scripts/extract-ikconfig
unbashify-extract-ikconfig.patch

scripts/extract-ikconfig contains a lot of gratuituous bashisms,
which make it fail if /bin/sh isn't bash. This patch replaces them
with regular Bourne shell constructs.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
