I've noticed that the aac driver in 4.10-RELEASE-p2 includes support for 
the Dell CERC SATA controller, but the aac driver in 5.2.1-RELEASE-p8 does 
not. Is this because changes elsewhere in the kernel break CERC support in 
5.x, or has it just not been backported from -CURRENT to 5.x-RELEASE? Can I 
just add the line for the CERC controller to aac_pci.c in 5.x and expect it 
to work?
