thread_info: move function declarations to linux/thread_info.h
There are a few __weak functions in kernel/fork.c, which architectures can override. If there is no prototype, the compiler warns about them: kernel/fork.c:164:13: error: no previous prototype for 'arch_release_task_struct' [-Werror=missing-prototypes] kernel/fork.c:991:20: error: no previous prototype for 'arch_task_cache_init' [-Werror=missing-prototypes] kernel/fork.c:1086:12: error: no previous prototype for 'arch_dup_task_struct' [-Werror=missing-prototypes] There are already prototypes in a number of architecture specific headers that have addressed those warnings before, but it's much better to have these in a single place so the warning no longer shows up anywhere.
