[ Upstream commit c6ebf2c528470a09be77d0d9df2c6617ea037ac5 ] Runs on the kernel with CONFIG_RISCV_ALTERNATIVE enabled: kexec -sl vmlinux Error: kexec_image: Unknown rela relocation: 34 kexec_image: Error loading purgatory ret=-8 and kexec_image: Unknown rela relocation: 38 kexec_image: Error loading purgatory ret=-8 The purgatory code uses the 16-bit addition and subtraction relocation type, but not handled, resulting in kexec_file_load failure. So add handle to arch_kexec_apply_relocations_add(). Tested on RISC-V64 Qemu-virt, issue fixed.

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.
