James Morse 84c57dbd3c arm64: kernel: arch_crash_save_vmcoreinfo() should depend on CONFIG_CRASH_CORE Since commit `23c85094fe` ("proc/kcore: add vmcoreinfo note to /proc/kcore") the kernel has exported the vmcoreinfo PT_NOTE on /proc/kcore as well as /proc/vmcore. arm64 only exposes it's additional arch information via arch_crash_save_vmcoreinfo() if built with CONFIG_KEXEC, as kdump was previously the only user of vmcoreinfo. Move this weak function to a separate file that is built at the same time as its caller in kernel/crash_core.c. This ensures values like 'kimage_voffset' are always present in the vmcoreinfo PT_NOTE.

README

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.
