Our genvdso tool performs some rather paranoid checking that the VDSO library isn't attempting to make use of a GOT by constraining the number of entries that the GOT is allowed to contain to the minimum 2 entries that are always generated by binutils. Unfortunately lld prior to revision 334390 generates a third entry, which is unused & thus harmless but falls foul of genvdso's checks & causes the build to fail. Since we already check that the VDSO contains no relocations it seems reasonable to presume that it also doesn't contain use of a GOT, which would involve relocations. Thus rather than attempting to work around this issue by allowing 3 GOT entries when using lld, simply remove the GOT checks which seem overly paranoid.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
