Subject: [PATCH 0/2] riscv: kexec: Support crash_save percpu and machine_kexec_mask_interrupts

From: Guo Ren <guoren@...ux.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
