exec: allocate PROT_NONE pages on top of RAM
This inserts a read and write protected page between RAM and QEMU memory, for file-backend RAM. This makes it harder to exploit QEMU bugs resulting from buffer overflows in devices using variants of cpu_physical_memory_map, dma_memory_map etc. Signed-off-by: Michael S.
