Merge tag 'dax-locking-for-4.7' into linus DAX locking for 4.7 - We use a bit in an exceptional radix tree entry as a lock bit and use it similarly to how page lock is used for normal faults. This fixes races between hole instantiation and read faults of the same index. - DAX PMD faults are disabled, and will be re-enabled when PMD locking is implemented.
