[PATCH 0/2] riscv: kexec: Support crash_save percpu and machine_kexec_mask_interrupts

Posted by guoren@kernel.org 3 years, 8 months ago

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.

Guo Ren (2):
  riscv: kexec: EOI active and mask all interrupts in kexec crash path
  riscv: kexec: Implement crash_smp_send_stop with percpu crash_save_cpu

Hey,
If these are fixes, are there fixes tags you could add?
I don't see one for either patch.
Thanks,
Conor.
