Will Deacon 5383f45db3 locking/barriers: Convert users of lockless_dereference() to READ_ONCE() ...

commit 3382290ed2 upstream.

[ Note, this is a Git cherry-pick of the following commit:

    506458efaf ("locking/barriers: Convert users of lockless_dereference() to READ_ONCE()")

  ... for easier x86 PTI code testing and back-porting. ]

READ_ONCE() now has an implicit smp_read_barrier_depends() call, so it
can be used instead of lockless_dereference() without any change in
semantics.
