Subject: [Qemu-devel] [PULL 04/20] mc146818rtc: drop unnecessary '#ifdef TARGET_I386'
Date: Fri, 19 May 2017 13:20:56 +0200 [thread overview]
Message-ID: <1495192872-27667-5-git-send-email-pbonzini@redhat.com> (raw)
In-Reply-To: <1495192872-27667-1-git-send-email-pbonzini@redhat.com>
From: Xiao Guangrong <xiaoguangrong@tencent.com>
If the code purely depends on LOST_TICK_POLICY_SLEW, we can simply
drop '#ifdef TARGET_I386' as only x86 can enable this tick policy
