Subject: [PATCH V4 0/3] riscv: kexec: Fxiup 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.

Also cleanup arm64, x86 declarations in asm/smp.h.

Changlogs:

v4:
 - Add cpu_ops[cpu]->cpu_stop() in ipi_cpu_crash_stop
 - Wording optimization in comments

V3:
https://lore.kernel.org/linux-riscv/20220819025444.2121315-1-guoren@kernel.org/
 - Fixup compile problem with !SMP, which reported by lkp@...el.com
 - Cleanup declarations in asm/smp.h
 - Add reviewed-by

V2:
https://lore.kernel.org/linux-riscv/20220817161258.748836-1-guoren@kernel.org/ 
 - Add Fixes tags
 - Remove extern from bool smp_crash_stop_failed(void)

  riscv: kexec: Fixup irq controller broken in kexec crash path
  riscv: kexec: Fixup crash_smp_send_stop without multi cores
  arch: crash: Remove duplicate declaration in smp.h
