From: Petr Tesarik <petr.tesarik.ext at huawei.com>

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 additional relocation types and removes the need
to implement a Global Offset Table (GOT) for the purgatory.

Petr Tesarik (2):
  riscv/kexec: handle R_RISCV_ADD16 and R_RISCV_SUB16 relocation types
  riscv/purgatory: do not link with string.o

Torsten Duwe (1):
  riscv/kexec: handle R_RISCV_CALL_PLT relocation type
