Subject: [PATCH 6/6] UefiCpuPkg/MpInitLib: Set new AP to idle state after switching BSP
Date: Mon, 26 Dec 2016 19:21:02 +0800	[thread overview]
Message-ID: <20161226112102.25512-7-jeff.fan@intel.com> (raw)
In-Reply-To: <20161226112102.25512-1-jeff.fan@intel.com>

We need to set new AP to idle state if it is expected to be waken up by new BSP
later.
