When CONFIG_MODULES is not set/enabled:
../arch/riscv/kernel/elf_kexec.c:353:9: error: unknown type name 'Elf_Rela'; did you mean 'Elf64_Rela'?
353 | Elf_Rela *relas;
| ^~~~~~~~
| Elf64_Rela
Replace Elf_Rela by Elf64_Rela to avoid relying on CONFIG_MODULES.

This patch supports kexec_file to load and relocate purgatory.
It works well on riscv64 QEMU, being tested with devmem.

This patch adds support for loading a kexec on panic (kdump) kernel.
It has been tested with vmcore-dmesg on riscv64 QEMU on both an smp
and a non-smp system.

This patch adds support for kexec_file on RISC-V. I tested it on riscv64
QEMU with busybear-linux and single core along with the OpenSBI firmware
fw_jump.bin for generic platform.
On SMP system, it depends on CONFIG_{HOTPLUG_CPU, RISCV_SBI} to
resume/stop hart through OpenSBI firmware, it also needs a OpenSBI that
support the HSM extension.
