For Yang Rong,
This patch need be put ahead of the utest patch to avoid regression. Thanks.

Subject: [PATCH v2 3/3] add bswap64 for gen7/gen75 and gen8 seperately.
From: Luo Xionghu <xionghu....@intel.com>
as the long type data layout is not continous on platform gen7/gen75, the
indirect address access pattern is a bit different than gen8.
