At LWN.net: "Ok, the patch is reasonably big, mainly due to a new architecture (cris)
and some updates to others (arm and mips). But what's interesting here are actually three very small patches:
- mm/memory.c (PageReserved() check): this could corrupt the shared zero
page if you used direct IO, and thus make your system unusable
- elevator fix (another missed re-initialization in __make_request(), and
this time we made sure to check that everything else _is_ initialized)
- IDE driver multi-mode write fix (ide_multwrite())."
