From: Tejun Heo <teheo@suse.de>
Subject: [PATCH] libata: fix ata_set_max_sectors()
References: 325552
Patch-Mainline: will be submitted after verified
In ata_set_max_sectors(), the highest nibble in LBA28 mode was
missing. This made drives sized between 8G and 128G with HPA turned
on to be resized to under 8G. Fix it.
