      ath9k: disable MIB interrupts to fix interrupt storm · 92cccc2c
      Luis R. Rodriguez 提交于
      Enabling the MIB interrupts has proven to cause an
      interrupt storm after 7 hours of run. We will make use of the
      MIB interrupt once we have ANI supported added so for now
      to cure this we disable the interrupt.
      
      The interrupt storm can be seen as follows after 7 hours of run
      as reported by  Steven Noonan <steven@uplinklabs.net>:
      
      18:28:38          sum   1106.00
      18:28:39          sum   1037.62
      18:28:40          sum   1069.00
      18:28:41          sum   1167.00
      18:28:42          sum   1155.00
      18:28:43          sum   1339.00
      18:28:44          sum  18355.00
      18:28:45          sum  17845.45
      18:28:46          sum  15285.00
      18:28:47          sum  17511.00
      18:28:48          sum  17568.69
      18:28:49          sum  17704.04
      18:28:50          sum  18566.67
      18:28:51          sum  18913.13
      
      at 18:28:44 the MIB interrupt kicked off and caused huge
      latency which can be seen even on a video he submitted:

      pcmcia: Fix broken abuse of dev->driver_data · cec5eb7b
      Alan Cox 提交于
      PCMCIA abuses dev->private_data in the probe methods. Unfortunately it
      continues to abuse it after calling drv->probe() which leads to crashes and
      other nasties (such as bogus probes of multifunction devices) giving errors like
      
      pcmcia: registering new device pcmcia0.1
      kernel: 0.1: GetNextTuple: No more items
      
      Extract the passed data before calling the driver probe function that way
      we don't blow up when the driver reuses dev->private_data as its right.
      
      As its close to the final release just move the hack so it works out,
      hopefully someone will be sufficiently embarrassed to produce a nice rework
      for 2.6.28.
