Aneesh Kumar K.V 0ec2698fe1 powerpc/mm: Check for matching hpte without taking hpte lock 
With smaller hash page table config, we would end up in situation
where we would be replacing hash page table slot frequently. In
such config, we will find the hpte to be not matching, and we
can do that check without holding the hpte lock. We need to
recheck the hpte again after holding lock.
