33e30239f1 sched: replace sync pause with async pause for nxtask_terminate
reason:
In the kernel, we are planning to remove all occurrences of up_cpu_pause as one of the steps to
simplify the implementation of critical sections. The goal is to enable spin_lock_irqsave to encapsulate critical sections,
thereby facilitating the replacement of critical sections(big lock) with smaller spin_lock_irqsave(small lock)

908df725ad arch: use up_current_regs/up_set_current_regs replace CURRENT_REGS
reason:
1 On different architectures, we can utilize more optimized strategies
  to implement up_current_regs/up_set_current_regs.
eg. use interrupt registersor percpu registers.

42d0e356c2 arch/addrenv: Change group_addrenv_t to arch_addrenv_t
This is preparation for moving address environments out of the group
structure into the tcb.

Why move ? Because the group is destroyed very early in the exit phase,
but the MMU mappings are needed until the context switch to the next
process is complete. Otherwise the MMU will lose its mappings and the
system will crash.
