Subject: [PATCH] x86/process: Export start_thread()

Commit e634d8fc792c ("x86-64: merge the standard and compat
start_thread() functions") removed exporting for the start_thread()
function in what seems like a typo. Add it back to
arch/x86/kernel/process_64.c for parity with process_32.c and other
arch.
