Subject: [PATCH V3] sched/rt, powerpc: Prepare for PREEMPT_RT
Date: Tue, 10 Nov 2020 16:53:30 +0800 [thread overview]
Message-ID: <1604998411-16116-1-git-send-email-wangqing@vivo.com> (raw)
PREEMPT_RT is a separate preemption model, CONFIG_PREEMPT will
be disabled when CONFIG_PREEMPT_RT is enabled, so we need
to add CONFIG_PREEMPT_RT output to __die().
Signed-off-by: Wang Qing <wangqing@vivo.com>
Changes in v3:
- Fix typo issue.
Changes in v2:
- Modify as Christophe suggested.
