'RELENG_7_0_0_RELEASE'.

This commit was manufactured to restore the state of the 7.0-RELEASE image.

- Remove variable _thr_scope_system, all threads are system scope.

2006-12-15T11:52:01+00:00

- Rename _thr_smp_cpus to boolean variable _thr_is_smp.
- Define CPU_SPINWAIT macro for each arch, only X86 supports it.

Eliminate atomic operations in thread cancellation functions, it should

2006-11-24T09:57:38+00:00

reduce overheads of cancellation points.

use rtprio_thread system call to get or set thread priority.

2006-09-21T04:21:30+00:00

Use umutex APIs to implement pthread_mutex, member pp_mutexq is added

2006-08-28T04:52:50+00:00

into pthread structure to keep track of locked PTHREAD_PRIO_PROTECT mutex,
no real mutex code is changed, the mutex locking and unlocking code should
has same performance as before.

Caching scheduling policy and priority in userland, a critical but baddly

2006-07-13T22:45:19+00:00

written application is frequently changing thread priority for SCHED_OTHER
policy.

Use thr_setscheduler, thr_getscheduler and thr_setschedparam to implement

2006-07-13T06:35:43+00:00

pthread functions.

Use kernel facilities to support real-time scheduling.

2006-07-12T06:13:18+00:00

WARNS level 4 cleanup.

2006-04-04T02:57:49+00:00

Remove priority mutex code because it does not work correctly,

2006-03-27T23:50:21+00:00

to make it work, turnstile like mechanism to support priority
propagating and other realtime scheduling options in kernel
should be available to userland mutex, for the moment, I just
want to make libthr be simple and efficient thread library.
