More efficient and simpler task termination.
Based on the assumption, that after its creation, only the task itself can create more threads for itself,
the last thread with userspace context to execute thread_exit() will perform futex and IPC cleanup. When
the task has no threads, it is destroyed. Both the cleanup and destruction is controlled by reference
counting.
As for userspace threads, even though there could be a global garbage collector for joining threads, it is
much simpler if the uinit thread detaches itself before switching to userspace.
task_kill() is now an idempotent operation. It just instructs the threads within a task to exit.
Change in the name of a thread state: Undead -> JoinMe. |

Fix the problem with sys_thread_create() by splitting the create and attach functionality of
thread_create(). Now it is possible to specify a flag that will cause thread_create() to only allocate and
initialize the thread structure. A call to thread_attach() will make the thread visible to the system.
This arrangement makes it easier to undo creation of a thread in case of a failure in sys_thread_create(). |

Fix two memory leaks.
In kernel, kernel_uarg structure needs to be deallocated when a thread
with userspace context is destroyed.
In userspace, the return value of the SYS_THREAD_CREATE must be checked
for error conditions and in case of error, uarg and stack must be freed
up. |

Cleanup the waitq_wakeup() interface.
Replace numeric constants (i.e. 0)
and boolean constants (i.e. false) with
more readable WAKEUP_FIRST. Also change the
type of the second argument of waitq_wakeup()
to a newly introduced type wakeup_mode_t.
Fix behaviour of waitq_wakeup() in case
that WAKEUP_ALL semantics is required
but no threads are sleeping in the wait
queue. This is a similar fix to that of
Jan Hudecek committed in the RCU branch,
but, IMHO, is more straightforward and
also doesn't eat up previous missed
wakeups. |

Fix a nasty bug in the TLB miss handlers on sparc64.
After we no longer lock the kernel stack in the DTLB,
there is a real danger of nested DTLB misses. The nested
miss can very easily clobber the DTLB Tag Access register.
Therefore, the original miss may not read this register, but
it has to receive its value as an argument. The argument
value is saved in the trap table when it is guaranteed that
the nested TLB miss will not occur. |

Remove printf() serialization from thread1 test in tester.
The agreement among developers seems to be that:
- there _must_ be a futex to serialize access to printf()
- there _must_ be pseudo thread serialization in printf()
- the best place for this is vprintf(), the one that goes to console |

Revert some of the changes introduced in revision 2209.
I think it is not correct to remove serialization of pseudo threads in printf_core.c.
With thread-level futex serialization, several pseudo threads running in one thread could easily deadlock
the task.
Add a dedicated futex serialization to thread1.c test only. |
