Subject: [PATCH v2 3/3] MdeModulePkg/Mem: Initialize the variable MapMemory
Date: Wed, 30 Oct 2019 22:08:30 +0800	[thread overview]
Message-ID: <20191030140830.31156-4-shenglei.zhang@intel.com> (raw)
In-Reply-To: <20191030140830.31156-1-shenglei.zhang@intel.com>

MapMemory is not initialized by FindGuardedMemoryMap
or CoreInternalAllocatePages which calls MapMemory.
So we give a 0 to it.
