Subject: [PATCH 01/46] kernel: Move prototype declaration to header file
 include/linux/thread_info.h

Move prototype declaration to header file include/linux/thread_info.h
from arch/mn10300/include/asm/thread_info.h and
arch/tile/include/asm/thread_info.h because it is used by more than one
file.
Also, include the header file in kernel/fork.c,
arch/mn10300/kernel/kgdb.c and arch/tile/kernel/process.c.

This also eliminates the following warning in kernel/fork.c:
kernel/fork.c:136:13: warning: no previous prototype for ‘arch_release_thread_info’ [-Wmissing-prototypes]
