Subject[patch 37/71] libata: OCZ Vertex cant do HPA
2.6.30-stable review patch.  If anyone has any objections, please let us know.

------------------
From: Tejun Heo <tj@kernel.org>

commit 7831387bda72af3059be48d39846d3eb6d8ce2f6 upstream.

OCZ Vertex SSD can't do HPA and not in a usual way. It reports HPA,
allows unlocking but then fails all IOs which fall in the unlocked
area. Quirk it so that HPA unlocking is not used for the device.

Reported by Daniel Perup in bnc#522414.
