The kexec_file_load(2) syscall does not work at least in some kernel
builds. For details see the relevant section in this blog post:

This patch series handles an additional relocation types, removes the need
to implement a Global Offset Table (GOT) for the purgatory and fixes the
placement of initrd.

  riscv/kexec: load initrd high in available memory
  riscv/kexec: handle R_RISCV_CALL_PLT relocation type
