bootlog 4.11

Hi!

I have compiled kernel 4.11 and this one seems to have changes in drivers/ata/sata_mv.c which will make my Buffalo Linksation unbootable! 4.10.17 is working like expected!

*** 4.10.17 bootlog: sata_mv f1080000.sata: slots 32 ports 2 ***
4.11 bootlog: sata_mv f1080000.sata: can't request region for resource [mem 0xf1080000-0xf1084fff] ***

I have patched the 4.11 version of drivers/ata/sata_mv.c back to the old 4.10.17 version and it works ;-)
