edf7b36669 runq_lock: Fix deadlock due to cpu migration. 
Symptom and analysis:
runq_lock of the migration source is acquired on
the migration destination CPU.

This happens in the following steps:
 (1) The thread stores value of cpu_local_var(runq_lock)
     to its register when trying to perform
     ihk_mc_spinlock_lock() on the lock variable.
 (2) The thread takes IPI and migrates to another CPU.
 (3) The thread resumes execution and acquires the wrong lock.

Solution:
* Disable interrupts before getting the value of
  cpu_local_var(runq_lock)

ba80dd8650 arm64: Fix for ptrace instruction rewrite on thunder-x2. 
- Fixed the problem that instruction rewriting by PTRACE_POKETEXT is not reflected.
   The cause is that the instruction cache was not flushed.

 - Add instruction chache flush in ptrace_report_signal().
