This patch applies to 2.6.31 and 2.6.30 (at least).  How far back
should it be ported?

There was no Cc:stable in the changelog.

There was no Cc:stable in the mail headers.  Nor cc:linux-ide.

Adding a Reported-by: is nice.

Please use the form

Addresses http://bugzilla.kernel.org/show_bug.cgi?id=14227

when mentioning bugzilla reports within changelogs.  To provide a nice
greppable pattern for those people who might close off old reports for us.
