    sh: fix smp_store_mb for !SMP · fb9b050c
    Michael S. Tsirkin authored
    sh variant of smp_store_mb() calls xchg() on !SMP which is stronger than
    implied by both the name and the documentation.
    
    commit 90a3ccb0 ("sh: define __smp_xxx,
    fix smp_store_mb for !SMP") was supposed to fix it but
    left the bug in place.
    
    Drop smp_store_mb, so that code in asm-generic/barrier.h
    will define it correctly depending on CONFIG_SMP.
