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

------------------

From: Henrique de Moraes Holschuh <hmh@hmh.eng.br>

This issue was fixed indirectly in mainline by commit
60a4ce7f4148155d3f28eea4a213f7ee47cd57b7.

acpi_ut_get_node_name() returns a four char fixed-size array, not
NULL-terminated.

This is the minimal fix for stable 2.6.28.
