26bebb2749 sched_request_migrate(): fix race condition between migration req and IRQs 
make sure the caller thread holds migration queue lock with IRQs disabled
until it notifies the target CPU so that an interrupt can not deschedule
it in the middle of the request.

67f5a1d4e0 migrate-cpu: Prevent migration target from calling schedule() twice 
Symptom:
A thread could call schedule() twice.

Cause:
 (1) The migrator raises rescheduling flag
 (2) The thread calls check_need_resched() for other
     reason than the migrate IPI, e.g, response to system call
     offload. And it finds that the flag is set and it's trying to
     call schedule().
 (3) The thread is interrupted by the migrate IPI and it finds that
     the flag is set and calls schedule() in the interrupt context.
 (4) The thread resumes the execution and call schedule()

Solution:
 (1) Reset the rescheduling flag when checking it and it's set
 (2) Set it again if it's decided not to call schedule()

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)
