4.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dave Carroll <david.carr...@microsemi.com>
commit 6c92f7dbf25c36f35320e4ae0b508676410bac04 upstream.
The logic for supporting large drives was previously tied to 4Kn support
for SmartIOC-2000. As SmartIOC-2000 does not support volumes using 4Kn
drives, use the intended option flag AAC_OPT_NEW_COMM_64 to determine
support for volumes greater than 2T.
