* Import my recent 1:1 threading working. some features improved includes:davidxu2005-04-0249-4267/+5873
| | | | | | | | | | | | | | | | 1. fast simple type mutex. 2. __thread tls works. 3. asynchronous cancellation works ( using signal ). 4. thread synchronization is fully based on umtx, mainly, condition variable and other synchronization objects were rewritten by using umtx directly. those objects can be shared between processes via shared memory, it has to change ABI which does not happen yet. 5. default stack size is increased to 1M on 32 bits platform, 2M for 64 bits platform. As the result, some mysql super-smack benchmarks show performance is improved massivly. Okayed by: jeff, mtm, rwatson, scottl

* 1. Now that it's a thread's state is changed from within the kernel, wheremtm2004-10-132-4/+10
| | | | | | | | | | | | | | no userland locks are heald, the dead thread lock can no longer protect access to it. Therefore, instead of using an if (!dead)...else clause after walking the active threads list test the thread pointer before deciding not to walk the dead threads list. If the thread pointer is null it means it was not found in the active threads list and the dead threads list should be checked. 2. Do not free the stack of a thread that is not marked dead. This is the 2nd and final part of eliminating the race to free a thread's stack. MFC after: 3 days

* Close a race between a thread exiting and the freeing of it's stack.mtm2004-10-061-3/+2
| | | | | | | | | After some discussion the best option seems to be to signal the thread's death from within the kernel. This requires that thr_exit() take an argument. Discussed with: davidxu, deischen, marcel MFC after: 3 days

* The SUSv3 function say that the affected functions MAY FAIL, if themtm2004-09-221-27/+6
| | | | | | | | | | | | specified mutex is invalid. In spec parlance 'MAY FAIL' means it's up to the implementor. So, remove the check for NULL pointers for two reasons: 1. A mutex may be invalid without necessarily being NULL. 2. If the pointer to the mutex is NULL core-dumping in the vicinity of the problem is much much much better than failing in some other part of the code (especially when the application doesn't check the return value of the function that you oh so helpfully set to EINVAL).

| | | | | | | | | | | | | | | | | | | | pointer to the corresponding struct thread to the thread ID (lwpid_t) assigned to that thread. The primary reason for this change is that libthr now internally uses the same ID as the debugger and the kernel when referencing to a kernel thread. This allows us to implement the support for debugging without additional translations and/or mappings. To preserve the ABI, the 1:1 threading syscalls, including the umtx locking API have not been changed to work on a lwpid_t. Instead the 1:1 threading syscalls operate on long and the umtx locking API has not been changed except for the contested bit. Previously this was the least significant bit. Now it's the most significant bit. Since the contested bit should not be tested by userland, this change is not expected to be visible. Just to be sure, UMTX_CONTESTED has been removed from <sys/umtx.h>. Reviewed by: mtm@ ABI preservation tested on: i386, ia64
