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

Changlogs:
v5:
 - Remove the patch which isn't relate to riscv
 - Add fixup crash_smp_send_stop test result

v4:
https://lore.kernel.org/linux-riscv/20220921033134.3133319-1-guoren@kernel.org/
 - 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/
