      Add parameter to add_partial to avoid having two functions · 7c2e132c
      Christoph Lameter authored
      
      
      Add a parameter to add_partial instead of having separate functions.  The
      parameter allows a more detailed control of where the slab pages is placed in
      the partial queues.
      
      If we put slabs back to the front then they are likely immediately used for
      allocations.  If they are put at the end then we can maximize the time that
      the partial slabs spent without being subject to allocations.
      
      When deactivating slab we can put the slabs that had remote objects freed (we
      can see that because objects were put on the freelist that requires locks) to
      them at the end of the list so that the cachelines of remote processors can
      cool down.  Slabs that had objects from the local cpu freed to them (objects
      exist in the lockless freelist) are put in the front of the list to be reused
      ASAP in order to exploit the cache hot state of the local cpu.
      
      Patch seems to slightly improve tbench speed (1-2%).

      If CONFIG_SYSFS is set then free the kmem_cache structure when
      sysfs tells us its okay.
      
      Otherwise there is the danger (as pointed out by
      Al Viro) that sysfs thinks the kobject still exists after
      kmem_cache_destroy() removed it.

      Catalin Marinas authored
      
      
      This patch adds dummy local timers for each CPU so that the board clock
      device is used to broadcast events to the other CPUs. The patch also
      adds the declaration for the dummy_timer_setup function (the equivalent
      of local_timer_setup when CONFIG_LOCAL_TIMERS is not set).
      
      Due to the way clockevents work, the dummy timer on the first CPU has to
      be registered before the board timer.

      vm audit: add VM_DONTEXPAND to mmap for drivers that need it · 2f98735c
      Nick Piggin authored
      
      
      Drivers that register a ->fault handler, but do not range-check the
      offset argument, must set VM_DONTEXPAND in the vm_flags in order to
      prevent an expanding mremap from overflowing the resource.
      
      I've audited the tree and attempted to fix these problems (usually by
      adding VM_DONTEXPAND where it is not obvious).

      Because hpet_rtc_interrupt()'s call to get_rtc_time() ends up
      resolving to include/asm-generic/rtc.h's (hilariously inlined)
      get_rtc_time(), which does spin_unlock_irq() from hard IRQ context.
      
      The obvious patch fixes it.
