kconfig: convert to SPDX License Identifier All files in lxdialog/ are licensed under GPL-2.0+, and the rest are under GPL-2.0. I added GPL-2.0 tags to test scripts in tests/. Documentation/process/license-rules.rst does not suggest anything about the flex/bison files. Because flex does not accept the C++ comment style at the very top of a file, I used the C style for zconf.l, and so for zconf.y for consistency.

Linux-2.6.12-rc2 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!

kconfig: convert linked list of files to hash table Currently, a linked list is used to keep track of all the Kconfig files that have ever been parsed. Every time the "source" statement is encountered, the linked list is traversed to check if the file has been opened before. This prevents the same file from being recorded in include/config/auto.conf.cmd again. Given 1500+ Kconfig files parsed, a hashtable is now a more optimal data structure. By the way, you may wonder why we check this in the first place. It matters only when the same file is included multiple times. In old days, such a use case was forbidden, but commit f094f8a1b273 ("kconfig: allow multiple inclusion of the same file") provided a bit more flexibility. Of course, it is almost hypothetical...

kconfig: incorrect 'len' field initialisation ? 1) The field 'len' of the 'gstr' structure seems to track the size of the memory already allocated for the "growable string". So the value of this field should be the same as the 'malloc()' just above, shouldn't it ?

menuconfig: wrap long help lines Help text for certain config options is very extensive (the text includes the names of all other options the option in question depends on). Long lines are not wrapped, making it impossible to see the list without scrolling horizontally. This patch adds some logic which wraps help screen lines at word boundaries to prevent truncating. Tested by running ARCH=powerpc make menuconfig O=/tmp/build which shows that the long lines are now wrapped, and ARCH=powerpc make xconfig O=/tmp/build to demonstrate that it still compiles and operates as expected.
