3.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
commit e2c70425f05219b142b3a8a9489a622c736db39d upstream.
The original code always set the upper 32 bits to zero because it was
doing a shift of the wrong variable.
Fixes: 1a4f550a09f8 ('[SCSI] arcmsr: 1.20.00.15: add SATA RAID plus other fixes')
