Is this specific to alpha? I wonder why we don't see this on other platforms?

The x86 version of <asm/pci.h> includes <linux/slab.h> which hides the
problem on x86 at least. There was a big cleanup of implicit
<linux/slab.h> inclusions few months ago which has exposed the
problem.

It's a bug in the driver, just add the include there.
