      radeon: Test for PCI root bus before assuming bus->self · 0bd252de
      Alex Williamson authored
      
      
      If we assign a Radeon device to a virtual machine, we can no longer
      assume a fixed hardware topology, like the GPU having a parent device.
      This patch simply adds a few pci_is_root_bus() tests to avoid passing
      a NULL pointer to PCI access functions, allowing the radeon driver to
      work in a QEMU 440FX machine with an assigned HD8570 on the emulated
      PCI root bus.

       - fixes for potential memory corruption problems in magicmouse and
         picolcd drivers (the HW would have to be manufactured to be
         deliberately evil to trigger those) which were found by Steven
         Vittitoe

      Pull btrfs fixes from Chris Mason:
       "The biggest of these comes from Liu Bo, who tracked down a hang we've
        been hitting since moving to kernel workqueues (it's a btrfs bug, not
        in the generic code).  His patch needs backporting to 3.16 and 3.15
        stable, which I'll send once this is in.
      
        Otherwise these are assorted fixes.  Most were integrated last week
        during KS, but I wanted to give everyone the chance to test the
        result, so I waited for rc2 to come out before sending"

      Pull trace buffer epoll hang fix from Steven Rostedt:
       "Josef Bacik found a bug in the ring_buffer_poll_wait() where the
        condition variable (waiters_pending) was set before being added to the
        poll queue via poll_wait().  This allowed for a small race window to
        happen where an event could come in, check the condition variable see
        it set to true, clear it, and then wake all the waiters.  But because
        the waiter set the variable before adding itself to the queue, the
        waker could have cleared the variable after it was set and then miss
        waking it up as it wasn't added to the queue yet.
      
        Discussing this bug, we realized that a memory barrier needed to be
        added too, for the rare case that something polls for a single trace
        event to happen (and just one, no more to come in), and miss the
        wakeup due to memory ordering.  Ideally, a memory barrier needs to be
        added on the writer side too, but as that will kill tracing
        performance and this is for a situation that tracing wasn't even
        designed for (who traces one instance of an event, use a printk
        instead!), this isn't worth adding the barrier.  But we can in the
        future add the barrier for when the buffer goes from empty to the
        first event, as that would cover this case"

      HID: picolcd: sanity check report size in raw_event() callback · 844817e4
      Jiri Kosina authored
      
      
      The report passed to us from transport driver could potentially be
      arbitrarily large, therefore we better sanity-check it so that raw_data
      that we hold in picolcd_pending structure are always kept within proper
      bounds.

      ALSA: hda - Set up initial pins for Acer Aspire V5 · 1a22e775
      Takashi Iwai authored
      Acer Aspire V5 doesn't set up the pins correctly at the cold boot
      while the pins are corrected after the warm reboot.  This patch gives
      the proper pin configs statically in the driver as a workaround.

      "struct inode_operations"->rename == NULL if
      "struct inode_operations"->rename2 != NULL .
      
      TOMOYO needs to check for both ->rename and ->rename2 , or
      a system on (e.g.) ext4 filesystem won't boot.
