Subject: [Patch v5 31/48] UefiCpuPkg/MpInitLib: Implementation of MpInitLibEnableDisableAP()
Date: Tue,  2 Aug 2016 16:59:31 +0800	[thread overview]
Message-ID: <1470128388-17960-32-git-send-email-jeff.fan@intel.com> (raw)
In-Reply-To: <1470128388-17960-1-git-send-email-jeff.fan@intel.com>

v4:
  1. Simply the internal function MpInitLibEnableDisableAP()'s function
     header due to it is duplicated with MpInitLibEnableDisableAP().
v3:
  1. Use CamelCase for mCheckAllAPsEvent, mStopCheckAllApsStatus.
