2.6.27-stable review patch. If anyone has any objections, please let us know.

------------------
From: Alex Chiang <achiang@hp.com>

commit 66f1705580f796a3f52c092e9dc92cbe5df41dd6 upstream.

We do not need to manage our own name parameter, especially since
the PCI core can change it on our behalf, in the case of duplicate
slot names.

Remove 'name' from shpchp's version of struct slot.

This change also removes the unused struct task_event from the
slot structure.
