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()

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)
