Generating the version kernel tag relies on "git describe" command to
get the latest Linus kernel tag.
However, when working from clones of Linus' git we may not have the latest
tag. For example, when working on Arnaldo's acme.git, we can have this:
$ git branch
perf/core
$ head -n 5 ../../Makefile | tail -n 4
VERSION = 5
PATCHLEVEL = 17
SUBLEVEL = 0
EXTRAVERSION = -rc3
$ git describe --abbrev=0 --match "v[0-9].[0-9]*"
v4.13-rc5
Indeed using tags is a problem as it relies on tags being pulled from
Linus' git (and pushed to the clone).
In commit a4147f0f91 ("perf tools: Fix perf version generation")
Robert introduced a change to use the kernelversion rule to generate the
kernel tag when no git tags are available.
However, as mentioned above, the tag we generate may be incorrect, so
just always use kernelversion to get the tag (apart from building perf
out of tree).

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
