We have a comment claiming __switch_to() cares about where cpu_context is located relative to cpu_domain in thread_info. However arm64 has never had a thread_info::cpu_domain field, and neither __switch_to nor cpu_switch_to care where the cpu_context field is relative to others. Additionally, the init_thread_info alias is never used anywhere in the kernel, and will shortly become problematic when thread_info is moved into task_struct. This patch removes both.
