From: Guo Ren <guoren at linux.alibaba.com>

Current riscv kexec can't crash_save percpu states and disable
interrupts properly. The patch series fix them.

Guo Ren (2):
  riscv: kexec: EOI active and mask all interrupts in kexec crash path
  riscv: kexec: Implement crash_smp_send_stop with percpu crash_save_cpu
