Well, yes, but the underlying allocators will also have to take the flag too
so that all the semantics are correct.

The obvious one is allocations from interrupt routines, which must be
GFP_ATOMIC (ignoring the issue of whether a driver should be doing a memory
allocation in an interrupt). Allocating large pools at driver initialisation
should probably be GFP_KERNEL as you say.
