[PATCH V4 0/3] riscv: kexec: Fxiup crash_save percpu and machine_kexec_mask_interrupts

[guoren]

From: Guo Ren <guoren@xxxxxxxxxxxxxxxxx>

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.
