Subject: [PATCH V2 0/2] riscv: kexec: Fixup 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, make kexec work correct.

Changes in v2:
 - Add Fixes tags
 - Remove extern from bool smp_crash_stop_failed(void)

v1: https://lore.kernel.org/linux-riscv/20220816012701.561435-1-guoren@kernel.org/

Guo Ren (2):
  riscv: kexec: Disable all interrupts in kexec crash path
  riscv: kexec: Fixup crash_smp_send_stop with percpu crash_save_cpu
