Currently we call cpu_reload_memory_map() from cpu_exec_init(), but this is not necessary: * KVM doesn't use the data structures maintained by cpu_reload_memory_map() (the TLB and cpu->memory_dispatch) * for TCG, we will call this function via tcg_commit() either as soon as tcg_cpu_address_space_init() registers the listener, or when the first MemoryRegion is added to the AddressSpace if the AS is empty when we register the listener The unnecessary call is awkward for adding support for multiple address spaces per CPU, so drop it.
