CONFIG_CROSS_MEMORY_ATTACH adds couple syscalls: process_vm_readv and process_vm_writev, it's a kind of IPC for copying data between processes. Currently this option is placed inside "Processor type and features".
This patch moves it into "General setup" (where all other arch-independed syscalls and ipc features are placed) and changes prompt string to less cryptic.
