Jian J Wang f9d0e5daa0 MdeModulePkg/DxeIplPeim: reserve page 0 for NULL pointer detection ... When a boot loader examines the memory map, it can see that location 0 is available memory. If it chooses to use that memory, and PcdNullPointerDetectionPropertyMask is enabled, use of memory in page 0 will cause an exception. This does occur when running the memtest86 program. Leaving page 0 available is for legacy support purpose. Since we have deprecated the support of legacy, the solution is just reserving it so that it cannot be allocated for other uses.
