With VMAP_STACK now always enabled on arm64, remove the CONFIG_VMAP_STACK checks from overflow stack definitions and related code in arch/arm64/kernel/traps.c. The overflow_stack and panic_bad_stack() logic are now unconditionally included, simplifying the source and matching the mandatory stack model.

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 reStructuredText 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.
