 kernel/commit/?h=arm-3.5&id=02349e60cbd5c0829c95f0037bd0b35f42146f98 check
 all ports in the read bitmap], instead of insisting on lock step between
 host and device firmware,

 ratelimit page allocation failure], to alleviate interactive response
  * [http://dev.laptop.org/git/olpc-
 kernel/commit/?h=arm-3.5&id=491188ebd4721f3c8804b7fa626e63d6fdd2ed09 add a
 delay hack], to avoid consuming all available CPU time,

 kernel/commit/?h=arm-3.5&id=551664ae7a7e7cbe154acbcaf3762ec2262a202c tweak
