Dirty logs currently get written with native "long" size. On little endian it doesn't matter if we use uint64_t instead though, because we'd still end up using the right bytes. On big endian, this does become a bigger problem, so we need to ensure that kernel and userspace talk the same language, which means getting rid of "long" and using a defined size instead. So I decided to use 64 bit types at all times. This doesn't break existing targets but will in conjunction with a patch I'll send to the KVM ML make dirty logs work with 32 bit userspace on 64 kernel with big endian.
