qword aligned address

[Oliver Ryan <oryan@physics.nuigalway.ie>]

Hi,
I hope this is the right place for this question -- if not sorry, and 
please forget about it.

I'm setting up scatter/gather dma for a PCI device.  The device requires to 
be passed a  descriptor (which will be of type struct containing 4 
integers), the address of which needs to be q-word aligned.  How do I 
declare the descriptor to make sure its address is qword aligned?

Thanks in advance.

Oliver.
