Guo Ren 9b932aadfc riscv: kexec: Fixup crash_smp_send_stop without multi cores Current crash_smp_send_stop is the same as the generic one in kernel/panic and misses crash_save_cpu in percpu. This patch is inspired by `78fd584cde` ("arm64: kdump: implement machine_crash_shutdown()") and adds the same mechanism for riscv.

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.

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.
