[S390] arch/s390/kvm: Use GFP_ATOMIC when a lock is held
The containing function is called from several places. At one of them, in
the function __sigp_stop, the spin lock &fi->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
// </smpl>
