      treewide: fix up files incorrectly marked executable · 262b42e0
      Linus Torvalds authored
      I'm not exactly clear on what strange workflow causes people to do it,
      but clearly occasionally some files end up being committed as executable
      even though they clearly aren't.
      
      This is a reprise of commit 90fda63f ("treewide: fix up files
      incorrectly marked executable"), just with a different set of files (but
      with the same trivial shell scripting).
      
      So apparently we need to re-do this every five years or so, and Joe
      needs to just keep reminding me to do so ;)

      tsnep: Fix TX queue stop/wake for multiple queues · 3d53aaef
      Gerhard Engleder authored
      netif_stop_queue() and netif_wake_queue() act on TX queue 0. This is ok
      as long as only a single TX queue is supported. But support for multiple
      TX queues was introduced with 76203137 and I missed to adapt stop
      and wake of TX queues.
      
      Use netif_stop_subqueue() and netif_tx_wake_queue() to act on specific
      TX queue.

      net/tg3: resolve deadlock in tg3_reset_task() during EEH · 6c4ca03b
      David Christensen authored
      During EEH error injection testing, a deadlock was encountered in the tg3
      driver when tg3_io_error_detected() was attempting to cancel outstanding
      reset tasks:

      Code inspection shows that both tg3_io_error_detected() and
      tg3_reset_task() attempt to acquire the RTNL lock at the beginning of
      their code blocks.  If tg3_reset_task() should happen to execute between
      the times when tg3_io_error_deteced() acquires the RTNL lock and
      tg3_reset_task_cancel() is called, a deadlock will occur.
      
      Moving tg3_reset_task_cancel() call earlier within the code block, prior
      to acquiring RTNL, prevents this from happening, but also exposes another
      deadlock issue where tg3_reset_task() may execute AFTER
      tg3_io_error_detected() has executed:

      ...
      
      This issue can be avoided by aborting tg3_reset_task() if EEH error
      recovery is already in progress.
