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.

d932e0af2a sched/procfs:use instrument to statistics run time max stack 
Usage:
1. CONFIG_FS_PROCFS_MAX_STACK_RECORD > 0, such as 32,
2. add '-finstrument-functions' to CFLAGS for What you want to check
   stack.
3. mount porcfs
4. cat /proc/<pid>/stack will print backtace & size
