From: Zhongjie Zhu <zhongjiez...@gmail.com>
there are different cases for _ISR_lock_ISR_disable() and _ISR_lock_ISR_enable()
in the case RTEMS_SMP is defined or RTEMS_PROFILING is defined, so remove the
related code.
../../../cpukit/include/rtems/score/threaddispatch.h: In function
'_Thread_Dispatch_disable':
