864bcf556e sched/nx_bringup: Set the initial stack size in kernel build as well 
After #7364 this now works, so use it for the init process. It makes sense
as the init process typically requires a big stack (due to init scripts).

11cc232de5 pthread_mutex_timedlock never returns EINTR 
According to posix spec, this function should never return `EINTR`.

This fixes the call to `pthread_mutex_take` so it keeps retrying the
lock and doesn't return `EINTR`

08f7152d9f nuttx/sched: remove nxsched_remove_readytorun from up_block_task 
It takes about 10 cycles to obtain the task list according to the task
status. In most cases, we know the task status, so we can directly
add the task from the specified task list to reduce time consuming.

e2df52390a SMP: fix crash when switch to new task which is still running 
Situation:

Assume we have 2 cpus, and busy run task0.

task0 -> task1                      task2 -> task0
1. remove task0 form runninglist
2. take task1 as new tcb
3. add task0 to blocklist
4. clear spinlock
                                    4.1 remove task2 form runninglist
                                    4.2 take task0 as new tcb
                                    4.3 add task2 to blocklist
                                    4.4 use svc ISR swith to task0
                                    4.5 crash
5. use svc ISR swith to task1

Fix:
Move clear spinlock to the end of svc ISR
