fe30f0fa82 sched/wdog:change g_wdtickbase update situation.
In the 'wd_timer',the callback function executed by 'wd_expiration' could call wd_start,and g_wdtickbase might be updated.Subsequently, g_wdtickbase is incremented by the value of ticks, causing g_wdtickbase to be greater than the actual passage of time.

a73f5f86dc sched: do not crash for priority multi-boost
aio client will queue asynchronous io requests to the worker threads.
if PRIORITY_INHERITANCE is enabled, client thread's priority will be
set to worker threads. There will be multi-boost/restore of worker
threads' priority and assert the system.

No need priority multi-boot/restore to worker thread because client
thread's priority is alway the same.

dbefe37a3a sigqueue: add signal type judgment logic
To determine whether a signal is real-time signal or standard signal, the POSIX standard https://www.man7.org/linux/man-pages/man7/signal.7.html defines a real-time signal between SIGRTMIN  and SIGRTMAX , which can store multiple copies, otherwise only one can be retained.

7737efd995 SMP: fix repeat entry timer_start
If we are running on a single CPU architecture, then we know interrupts
are disabled and there is no need to explicitly call enter_critical_section().
However, in the SMP case, enter_critical_section() is required prevent
multiple cpu to enter timer_start.

1552e52e14 signal: fix group signal can't dispatch some parent group twice
reproduce:

static void *pthread(void *arg)
{
  system(arg);
}

void test (int argc, char *argv[])
{
  pthread_create(&pthread0, &attr, pthread, argv[1]);
  pthread_create(&pthread1, &attr, pthread, argv[2]);
}

only one pthread system() returnd, othres hanged

rootcause:

As we known, system() will create a new task called:
system -c XX

The example:
parent group               child groups

pthread0 -> waitpid() -> system -c ps -> exit() -> nxtask_signalparent()
pthread1 -> waitpid() -> system -c ls -> exit() -> nxtask_signalparent()

Each child group exit with function nxtask_signalparent(),

As we expect:

system -c ps will signal pthread0
system -c ls will signal pthread1

But actually:

system -c ps will signal pthread0/1
system -c ls will signal pthread0/1

As the spec, we know, this behavior is normal:
https://man7.org/linux/man-pages/man2/sigwaitinfo.2.html

So for this situation, when the signo is SIGCHLD, we broadcast.

f324d1d8dd SMP: fix repeat entry oneshot_tick_start
Situation:

Assume we have 2 cpus.

CPU0                                CPU1
1. -> nxsched_alarm_expiration
2. -> nxshced_timer_start
3. -> ONESHOT_TICK_START
4. now timer in IRQ
                                    5. in thread
                                    6. -> wd_start
                                    7. -> nxshced_timer_start
                                    8. -> ONESHOT_TICK_START
                                    9. reentry timer crash

Fix:
Enter critical section before nxsched_timer_start
