      Pull SCSI fixes from James Bottomley:
       "Eight fixes.
      
        The most important one is the mpt3sas fix which makes the driver work
        again on big endian systems. The rest are mostly minor error path or
        checker issues and the vmw_scsi one fixes a performance problem"

      init: rename and re-order boot_cpu_state_init() · b5b1404d
      Linus Torvalds authored
      This is purely a preparatory patch for upcoming changes during the 4.19
      merge window.
      
      We have a function called "boot_cpu_state_init()" that isn't really
      about the bootup cpu state: that is done much earlier by the similarly
      named "boot_cpu_init()" (note lack of "state" in name).
      
      This function initializes some hotplug CPU state, and needs to run after
      the percpu data has been properly initialized.  It even has a comment to
      that effect.
      
      Except it _doesn't_ actually run after the percpu data has been properly
      initialized.  On x86 it happens to do that, but on at least arm and
      arm64, the percpu base pointers are initialized by the arch-specific
      'smp_prepare_boot_cpu()' hook, which ran _after_ boot_cpu_state_init().
      
      This had some unexpected results, and in particular we have a patch
      pending for the merge window that did the obvious cleanup of using
      'this_cpu_write()' in the cpu hotplug init code:
      
        -       per_cpu_ptr(&cpuhp_state, smp_processor_id())->state = CPUHP_ONLINE;
        +       this_cpu_write(cpuhp_state.state, CPUHP_ONLINE);
      
      which is obviously the right thing to do.  Except because of the
      ordering issue, it actually failed miserably and unexpectedly on arm64.
      
      So this just fixes the ordering, and changes the name of the function to
      be 'boot_cpu_hotplug_init()' to make it obvious that it's about cpu
      hotplug state, because the core CPU state was supposed to have already
      been done earlier.
      
      Marked for stable, since the (not yet merged) patch that will show this
      problem is marked for stable.
