In each case, the containing function is only called from one place, where
a spin lock is held.
The semantic patch that makes this change is as follows:

// <smpl>
@gfp exists@
identifier fn;
position p;

fn(...) {
... when != spin_unlock
when any
GFP_KERNEL@p
... when any
}
@locked@
identifier gfp.fn;
@@
spin_lock(...)
... when != spin_unlock
fn(...)
@depends on locked@
position gfp.p;
@@
- GFP_KERNEL@p
+ GFP_ATOMIC
