      Pull minor tracing fixes from Steven Rostedt:
       "This includes three minor fixes, mostly due to cut-and-paste issues.
      
        The first is a cut and paste issue that changed the amount of stack to
        skip when tracing a stack dump from 0 to 6, which basically made the
        stack disappear for small stack traces.
      
        The second fix is just removing an unused field in a struct that is no
        longer used, and currently just wastes space.
      
        The third is another cut-and-paste fix that had a tracepoint recording
        the wrong field (it was recording the previous field a second time)"

           startup.

      vmstat: Remove BUG_ON from vmstat_update · 587198ba
      Christoph Lameter authored
      If we detect that there is nothing to do just set the flag and do not
      check if it was already set before.  Races really do not matter.  If the
      flag is set by any code then the shepherd will start dealing with the
      situation and reenable the vmstat workers when necessary again.
      
      Since commit 0eb77e98 ("vmstat: make vmstat_updater deferrable again
      and shut down on idle") quiet_vmstat might update cpu_stat_off and mark
      a particular cpu to be handled by vmstat_shepherd.  This might trigger a
      VM_BUG_ON in vmstat_update because the work item might have been
      sleeping during the idle period and see the cpu_stat_off updated after
      the wake up.  The VM_BUG_ON is therefore misleading and no more
      appropriate.  Moreover it doesn't really suite any protection from real
      bugs because vmstat_shepherd will simply reschedule the vmstat_work
      anytime it sees a particular cpu set or vmstat_update would do the same
      from the worker context directly.  Even when the two would race the
      result wouldn't be incorrect as the counters update is fully idempotent.

      When building with XZ compression copy ashldi3.c to the build
      directory to use a different object file for the kernel and zboot.
      Without this the same object file need to be build with different
