Documentation/barriers/kokr: Remove references to [smp_]read_barrier_depends()
Documentation/barriers: Remove references to [smp_]read_barrier_depends()
locking/barriers: Remove definitions for [smp_]read_barrier_depends()
alpha: Replace smp_read_barrier_depends() usage with smp_[r]mb()
vhost: Remove redundant use of read_barrier_depends() barrier
asm/rwonce: Don't pull <asm/barrier.h> into 'asm-generic/rwonce.h'
