      mei: nfc: fix deadlock on shutdown/suspend path · 4f273959
      Tomas Winkler authored
      In function mei_nfc_host_exit mei_cl_remove_device cannot be called
      under the device mutex as device removing flow invokes the device driver
      remove handler that calls in turn to mei_cl_disable_device which
      naturally acquires the device mutex.
      
      Also remove mei_cl_bus_remove_devices which has the same issue, but is
      never executed as currently the only device on the mei client bus is NFC
      and a new device cannot be easily added till the bus revamp is
      completed.
      
      This fixes regression caused by commit be9b720a ("mei_phy: move all
      nfc logic from mei driver to nfc")
      
      Prior to this change the nfc driver remove handler called to no-op
      disable function while actual nfc device was disabled directly from the
      mei driver.

      PM / wakeirq: Avoid setting power.wakeirq too hastily · 6d3dab7d
      Rafael J. Wysocki authored
      If dev_pm_attach_wake_irq() fails, the device's power.wakeirq field
      should not be set to point to the struct wake_irq passed to that
      function, as that object will be freed going forward.
      
      For this reason, make dev_pm_attach_wake_irq() first call
      device_wakeup_attach_irq() and only set the device's power.wakeirq
      field if that's successful.
      
      That requires device_wakeup_attach_irq() to be called under the
      device's power.lock lock, but since dev_pm_attach_wake_irq() is
      the only caller of it, the requisite changes are easy to make.

      perf tools: Copy rbtree.h from the kernel · 4407f967
      Arnaldo Carvalho de Melo authored
      We were using the include/linux/rbtree.h directly from the kernel,
      which broke the build as soon as it started using rcupdate.h, to
      avoid dragging the rcu header files into tools/, for which there is
      no use so far, grab a copy of rbtree.h.
      
      This is the minimal fix, later patches will copy as well lib/rbtree.c
      and move rbtree.h into tools/include/, etc.

      ext4: replace open coded nofail allocation in ext4_free_blocks() · 7444a072
      Michal Hocko authored
      ext4_free_blocks is looping around the allocation request and mimics
      __GFP_NOFAIL behavior without any allocation fallback strategy. Let's
      remove the open coded loop and replace it with __GFP_NOFAIL. Without the
      flag the allocator has no way to find out never-fail requirement and
      cannot help in any way.

      bluetooth: fix list handling · 9b284cbd
      Linus Torvalds authored
      Commit 835a6a2f ("Bluetooth: Stop sabotaging list poisoning")
      thought that the code was sabotaging the list poisoning when NULL'ing
      out the list pointers and removed it.
      
      But what was going on was that the bluetooth code was using NULL
      pointers for the list as a way to mark it empty, and that commit just
      broke it (and replaced the test with NULL with a "list_empty()" test on
      a uninitialized list instead, breaking things even further).
      
      So fix it all up to use the regular and real list_empty() handling
      (which does not use NULL, but a pointer to itself), also making sure to
      initialize the list properly (the previous NULL case was initialized
      implicitly by the session being allocated with kzalloc())
      
      This is a combination of patches by Marcel Holtmann and Tedd Ho-Jeong
      An.
      
      [ I would normally expect to get this through the bt tree, but I'm going
        to release -rc1, so I'm just committing this directly   - Linus ]
