a9973e913d uti: futex call function in mcctrl 
Previously, futex code of McKerenl was called by mccontrol,
but there ware some problems with this method.
(Mainly, location of McKernel image on memory)

Call futex code in mcctrl instead of the one in McKernel image,
giving the following benefits:
1. Not relying on shared kernel virtual address space with Linux any more
2. The cpu id store / retrieve is not needed and resulting in the code

9f39d1cd88 move_pages: Fix and support some specs for LTP. 
1. When nodes array is NULL, move_pages doesn't move any pages,
 instead will return the node where each page
 currently resides by status array.
2. Check whether all specified node is online or not.

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)
