Subject: [PATCH 4/8] powerpc: invoke jump_label_init() in a much earlier stage
Date: Thu, 20 Aug 2015 20:14:32 +0800 [thread overview]
Message-ID: <1440072876-8321-5-git-send-email-haokexin@gmail.com> (raw)
In-Reply-To: <1440072876-8321-1-git-send-email-haokexin@gmail.com>
So we can use static_key for cpu_has_feature() and mmu_has_feature().
