REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1236 When "dmem" runs without additional arguments, it dumps the memory content of EFI_SYSTEM_TABLE. But today's implementation dumps 512 bytes. It's not correct because sizeof (EFI_SYSTEM_TABLE) is less than 512, the 512-read causes page fault exception in a heap-guard enabled environment. The patch changes the implementation to only dump sizeof (EFI_SYSTEM_TABLE) bytes for gST.
