23  * Based on Intel specification:
24  * http://www.intel.com/content/dam/www/public/us/en/documents/datasheets/xeon-e3-1200v3-vol-2-datasheet.pdf
25  * http://www.intel.com/content/www/us/en/processors/xeon/xeon-e3-1200-family-vol-2-datasheet.html
26  * http://www.intel.com/content/www/us/en/processors/core/7th-gen-core-family-mobile-h-processor-lines-datasheet-vol-2.html
27  *
28  * According to the above datasheet (p.16):
29  * "
30  * 6. Software must not access B0/D0/F0 32-bit memory-mapped registers with
31  * requests that cross a DW boundary.
32  * "
33  *
34  * Thus, we make use of the explicit: lo_hi_readq(), which breaks the readq into
35  * 2 readl() calls. This restriction may be lifted in subsequent chip releases,
36  * but lo_hi_readq() ensures that we are safe across all e3-1200 processors.
