With [1], crash dump specific code is moved out of CONFIG_KEXEC_CORE and placed under CONFIG_CRASH_DUMP, where it is more appropriate. And since CONFIG_KEXEC & !CONFIG_CRASH_DUMP build option is supported with that, it led to the below warning: "WARN: resolve_btfids: unresolved symbol crash_kexec" Fix it by using the appropriate #ifdef.

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.
