Why? E.g. is 0xc0000000 unconditionally reserved, not guaranteed to be valid, something else? > So, do you have any suggesstion? Hmm, I think ideally kvm_util_base.h would define a range of memory that can be used by tests for arbitrary data. Multiple tests use 0xc0000000, which is not entirely arbitrary, i.e. it doesn't _need_ to be 0xc0000000, but 0xc0000000 is convenient because it's 32-bit addressable and doesn't overlap reserved areas in other architectures.
