      radeon kms: do not flush uninitialized hotplug work · a01c34f7
      Sergey Senozhatsky authored
      Fix a warning from lockdep caused by calling flush_work() for
      uninitialized hotplug work. Initialize hotplug_work, audio_work
      and reset_work upon successful radeon_irq_kms_init() completion
      and thus perform hotplug flush_work only when rdev->irq.installed
      is true.

      Pull slab update from Pekka Enberg:
       "Highlights:
      
        - Fix for boot-time problems on some architectures due to
          init_lock_keys() not respecting kmalloc_caches boundaries

        - CONFIG_SLUB_CPU_PARTIAL requested by RT folks (Joonsoo Kim)
      
        - Fix for excessive slab freelist draining (Wanpeng Li)
      
        - SLUB and SLOB cleanups and fixes (various people)"
      
      I ended up editing the branch, and this avoids two commits at the end
      that were immediately reverted, and I instead just applied the oneliner
      fix in between myself.

      Now, this uses SLUB pretty much unmodified, but as it is the -rt kernel
      with CONFIG_PREEMPT_RT set, spinlocks are mutexes, although they do
      disable migration. But the SLUB code is relatively lockless, and the
      spin_locks there are raw_spin_locks (not converted to mutexes), thus I
      believe this bug can happen in mainline without -rt features. The -rt
      patch is just good at triggering mainline bugs ;-)
      
      Anyway, looking at where this crashed, it seems that the page variable
      can be NULL when passed to the node_match() function (which does not
      check if it is NULL). When this happens we get the above panic.
      
      As page is only used in slab_alloc() to check if the node matches, if
      it's NULL I'm assuming that we can say it doesn't and call the
      __slab_alloc() code. Is this a correct assumption?

      If radeon_cs_parser_relocs fails ttm_eu_backoff_reservation doesn't get called.
      This left open a bug where ttm_eu_reserve_buffers succeeded but the bo's were
      not unlocked afterwards:

      This is a regression caused by commit ecff665f.

      Alex Deucher authored
      They still seem to cause instability on some r6xx parts.
      As a follow up, we can switch to using CP DMA for bo
      moves on r6xx as a lighter weight alternative to using
      the 3D engine.
      
      A version of this patch should also go to stable kernels.
