The 'source' builtin is a bash alias to the '.' (dot) builtin. While the
former is supported only by bash, the latter is specified in POSIX and
works fine with all POSIX-compliant shells I am aware of.
The '$_' special parameter is specific to bash. It is partially
supported in dash too but it always evaluates to the current script path
(which causes the script to enter a loop recursively re-executing
itself). This is why I have replaced the two occurences of '$_' with the
explicit parameter.
The 'local' builtin is another example of bash-specific code. Although
it is supported by all POSIX-compliant shells I am aware of, it is not
part of POSIX specification and thus the code should not rely on it
assigning a specific value to the local variable. Moreover, the 'posh'
shell has a limited version of 'local' builtin not supporting direct
variable assignments. Thus, I have broken one of the 'local'
declarations down into a (non-POSIX) 'local' declaration and a plain
(POSIX-compliant) variable assignment.

Now that we run scripts/setlocalversion during every build, it makes
sense to move all the localversion logic there. This cleans up the
toplevel Makefile and also makes sure that the script is called only
once in 'make prepare' (previously, it would be called every time due to
a variable expansion in an ifneq statement). No user-visible change is
intended, unless one runs the setlocalversion script directly.

When using trees like wireless-testing, which have untagged tags,
scripts/setlocalversion does not display any git indication for
localversion.
This patch fixes it: If git is available, but no usable tag is found,
it uses -g${head}. It skips the detection of unanottated tags via
git name-rev.

setlocalversion used to use an abbreviated git commit sha1 to generate the
tag. This was changed in commit d882421f4e08ddf0a94245cdbe516db260aa6f41
"kbuild: change CONFIG_LOCALVERSION_AUTO to use a git-describe-ish format"
to use git describe to come up with a tag. Which is nice, but git describe
sometimes can't describe the revision.
Commit 56b2f0706d82535fd8d85503f2dcc0be40c8e55d ("setlocalversion: do not
describe if there is nothing to describe") addressed this, but there is still
no tag generated.
So, generate a plain abbreviated sha1 tag like setlocalversion used to when
git describe comes up short.

make-kpkg modifies scripts/package/Makefile and deletes
scripts/package/builddeb as part of its build process. Ignore these
changes so the tree isn't marked as -dirty, when it is just an
artifact of make-kpkg. (make-kpkg clean restores the files to their
original state, and these helper scripts won't affect the final
compiled kernel in any way.)

If git's index file is out of date, and some files have been touched
such that their timestamp doesn't what is in the index, "git
diff-index HEAD" may show that a particular file is dirty, when in
fact it really isn't. Running "git update-index" will update the
index to avoid these false positives.

Change the automatic local version to have the form -nnnnn-gSHA1SUMID,
where 'nnnnn' is the number of commits since the last tag (i.e.,
2.6.21-rc7). This makes it much more likely that the package names created
for the kernel will look "newer" to a package manager.

adds revision suffix for untagged commits that are reachable from a tag
I'm bisecting and don't get the -g...... suffix. The reason is, that
git name-rev --tags HEAD
returns e.g.
HEAD tags/v2.6.17-rc1^0~1067
which is currently good enough for setlocalversion to skip the suffix.
This introduces a dependecy to grep -E, which should be fine.

Currently scripts/setlocalversion is a Perl script that tries to figure
out the current git commit ID of a repo without using git. It also
imports Digest::MD5 without using it and generally is too big for the
small task it does. :] And it always reports a git ID, even when the
HEAD is tagged -- this is a bug.
This patch replaces it with a Bourne Shell script that uses git
commands to do the same. I can't come up with a scenario where someone
would use a git repo and refuse to install git core at the same time,
so I think it's reasonable to assume git is available.
The new script also reports uncommitted changes by adding -git_dirty to
the version string. Obviously you can't see from that _what_ has been
changed from the last commit, so it's more of a reminder that you
forgot to commit something.
The script is easily extensible: simply add a check for Mercurial (or
whatever) below the git check.
Note: the script doesn't print a newline char anymore. That's only
because it was easier to implement it that way, not a feature (or bug).
'make kernelrelease' doesn't care.

upon the git commit
If CONFIG_AUTO_LOCALVERSION is set, the user is using a git-based tree, and the
current HEAD is not referred to by any tags in .git/refs/tags/, append -g and
the first 8 characters of the commit to the version string. This makes it
easier to use git-bisect, and/or to do a daily build, without trampling on your
older, working builds, or accidentally setting up conflicting sets of modules.
