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)
