      Bug cause is blast_dcache_range() in preemptible code [in
      r4k_dma_cache_wback_inv()].
      blast_dcache_range() is constructed via __BUILD_BLAST_CACHE_RANGE that
      uses cpu_dcache_line_size(). It uses current_cpu_data that use
      smp_processor_id() in turn. In case of CONFIG_DEBUG_PREEMPT
      smp_processor_id emits BUG if we are executing with preemption
      enabled.
      
      Cpu options of cpu0 are assumed to be the superset of all processors.
      
      Can I make the same assumptions for cache line size  and fix this
      issue the following way:

      IB/ehca: Fix static rate if path faster than link · b1812582
      Joachim Fenkes 提交于
      The formula would yield -1 if the path is faster than the link, which
      is wrong in a bad way (max throttling).  Clamp to 0, which is the
      correct value.

      Fix kmem_cache_free performance regression in slab · 80cbd911
      Matthew Wilcox 提交于
      The database performance group have found that half the cycles spent
      in kmem_cache_free are spent in this one call to BUG_ON.  Moving it
      into the CONFIG_SLAB_DEBUG-only function cache_free_debugcheck() is a
      performance win of almost 0.5% on their particular benchmark.
      
      The call was added as part of commit ddc2e812
      with the comment that "overhead should be minimal".  It may have been
      minimal at the time, but it isn't now.
      
      [ Quoth Pekka Enberg: "I don't think the BUG_ON per se caused the
        performance regression but rather the virt_to_head_page() changes to
        virt_to_cache() that were added later." ]
