exit: Implement kthread_exit
[ Upstream commit bbda86e988d4c124e4cfa816291cbd583ae8bfb1 ]
The way the per task_struct exit_code is used by kernel threads is not
quite compatible how it is used by userspace applications. The low
byte of the userspace exit_code value encodes the exit signal. While
kthreads just use the value as an int holding ordinary kernel function
exit status like -EPERM.
Add kthread_exit to clearly separate the two kinds of uses.
