In userspace emulation how do I make a set of addresses always valid and
initialized to 0 even though the process does not map it in? In particular
I want to map the CVMSEG for Cavium qemu-mips64 and qemu-mipsn32. The
addresses would be 0xFFFFFFFFFFFF8000 - 0xFFFFFFFFFFFFBFFF. I've looked at
target_mmap but it can't handle addresses that large. The lack of an
emulated mmu for 64 bit guests is going to be a problem.
