Ying Sun a39416d859 riscv/kexec_file: Fix relocation type R_RISCV_ADD16 and R_RISCV_SUB16 unknown ... [ Upstream commit c6ebf2c528 ] 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.
