Merge patch series "riscv: kexec: Fxiup crash_save percpu and machine_kexec_mask_interrupts"
guoren@kernel.org <guoren@kernel.org> says:
From: Guo Ren <guoren@linux.alibaba.com>
Current riscv kexec can't crash_save percpu states and disable
interrupts properly. The patch series fix them, make kexec work correct.
* b4-shazam-merge:
riscv: kexec: Fixup crash_smp_send_stop without multi cores
riscv: kexec: Fixup irq controller broken in kexec crash path
