The required buffer size for InitOrder will be 96K when NumberOfCpus=1024. sizeof (CPU_FEATURES_INIT_ORDER) = 96 NumberOfCpus = 1024 = 1K sizeof (CPU_FEATURES_INIT_ORDER) * NumberOfCpus = 96K AllocateZeroPool() will call to PeiServicesAllocatePool() which will use EFI_HOB_MEMORY_POOL to management memory pool. EFI_HOB_MEMORY_POOL.Header.HobLength is UINT16 type, so there is no way for AllocateZeroPool() to allocate > 64K memory. So AllocateZeroPool() could not be used anymore for the case above or even bigger required buffer size. This patch updates the code to use AllocatePages() instead of AllocateZeroPool() to allocate buffer for InitOrder.
