commit db16c1fe92 upstream.
[backported for dependency only extra_paholeopt variable setup and
usage, we don't want floats generated in 5.10]
pahole v1.21 supports the --btf_gen_floats flag, which makes it
generate the information about the floating-point types [1].
Adjust link-vmlinux.sh to pass this flag to pahole in case it's
supported, which is determined using a simple version check.

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.
