      mei: me: clear interrupts on the resume path · 42f132fe
      Tomas Winkler 提交于
      We need to clear pending interrupts on the resume
      path. This brings the device into defined state
      before starting the reset flow
      
      This should solve suspend/resume issues:

      mei: init: Flush scheduled work before resetting the device · 5e85b364
      Samuel Ortiz 提交于
      Flushing pending work items before resetting the device makes more
      sense than doing so afterwards. Some of them, like e.g. the NFC
      initialization one, find themselves with client IDs changed after
      the reset, eventually leading to trigger a client.c:mei_me_cl_by_id()
      warning after a few modprobe/rmmod cycles.

      Tulip throws an error when dma debugging is enabled, as it doesn't properly
      check dma mapping results with dma_mapping_error() durring tx ring refills.
      
      Easy fix, just add it in, and drop the frame if the mapping is bad

      of: Fix locking vs. interrupts · d25d8694
      Benjamin Herrenschmidt 提交于
      The OF code uses irqsafe locks everywhere except in a handful of functions
      for no obvious reasons. Since the conversion from the old rwlocks, this
      now triggers lockdep warnings when used at interrupt time. At least one
      driver (ibmvscsi) seems to be doing that from softirq context.
      
      This converts the few non-irqsafe locks into irqsafe ones, making them
      consistent with the rest of the code.
