To fix an issue in which enabling NX feature will mark the AP wakeup buffer as non-executable and fail the AP init, the buffer was split into two part: the lower part in memory within 1MB and the higher part within allocated executable memory (EfiBootServicesCode). But the address of higher part memory was stored in lower part memory, which is actually shared with legacy components and will be overwritten by LegacyBiosDxe driver if CSM is enabled. This patch fixes this issue by storing the address of higher part memory in CpuMpData instead of ExchangeInfo.
