Subject: [Qemu-devel] [PATCH v2 3/5] mc146818rtc: ensure LOST_TICK_POLICY_SLEW is only enabled on TARGET_I386
Date: Thu,  4 May 2017 19:59:46 +0800	[thread overview]
Message-ID: <20170504115948.3048-4-xiaoguangrong@tencent.com> (raw)
In-Reply-To: <20170504115948.3048-1-xiaoguangrong@tencent.com>

From: Xiao Guangrong <xiaoguangrong@tencent.com>

Any tick policy specified on other platforms rather on TARGET_I386
will fall back to LOST_TICK_POLICY_DISCARD silently, this patch makes
sure only TARGET_I386 can enable LOST_TICK_POLICY_SLEW

After that, we can enable LOST_TICK_POLICY_SLEW in the common code
which need not use '#ifdef TARGET_I386' to make these code be x86
specific anymore
