[NOTES:
* I really hope that at least _some_ of the bugs below have been already
fixed, but I didn't have the time to search through all of the histories.
_Please_ let me know which of them can be closed.
* If you close one of the bugs in this list, please do your best to put the
hash of the fix commit into the Bugzilla entry.]

This message contains a list of some regressions introduced between 2.6.31 and
2.6.32, for which there are no fixes in the mainline I know of. If any of them
have been fixed already, please let me know.

If you know of any other unresolved regressions introduced between 2.6.31
and 2.6.32, please let me know either and I'll add them to the list.
Also, please let me know if any of the entries below are invalid.

issue.
