Will Deacon c2bc66082e locking/barriers: Add implicit smp_read_barrier_depends() to READ_ONCE() 
[ Note, this is a Git cherry-pick of the following commit:

    76ebbe78f7 ("locking/barriers: Add implicit smp_read_barrier_depends() to READ_ONCE()")

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

In preparation for the removal of lockless_dereference(), which is the
same as READ_ONCE() on all architectures other than Alpha, add an
implicit smp_read_barrier_depends() to READ_ONCE() so that it can be
used to head dependency chains on all architectures.
