Subject: [PATCH 0/2] riscv: kexec: Support crash_save percpu and machine_kexec_mask_interrupts
Date: Mon, 15 Aug 2022 21:26:59 -0400 [thread overview]
Message-ID: <20220816012701.561435-1-guoren@kernel.org> (raw)
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
