The following commit:
095b7a3e7745 ("x86/entry: Convert double fault exception to IDTENTRY_DF")
introduced a new build warning on 64-bit allnoconfig kernels, that have CONFIG_VMAP_STACK disabled:
arch/x86/kernel/traps.c:332:16: warning: unused variable ‘address’ [-Wunused-variable]
This variable is only used if CONFIG_VMAP_STACK is defined, so make it
dependent on that, not CONFIG_X86_64.

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.
