Hmm, so what this means is that exit_thread() can now be called for
threads which are not running on the CPU. So, I think the comment
in arch/arm/vfp/vfpmodule.c needs to be updated:
* THREAD_NOTIFY_EXIT
* - the thread (v) will be running on the local CPU, so
* v === current_thread_info()
along with this change, since that becomes false.
The code, however, looks like it'll cope just fine with that being
false, as will the other users of THREAD_NOTIFY_EXIT in ARM.
Thanks.
