The review for 07/14 made me expect an update - perhaps tweak the asm
constraints and add a comment.  This can be addressed later, as long as
we don't forget.

However
https://lkml.kernel.org/r/20250324104702.12139E73-hca@linux.ibm.com
needs to be addressed before a merge.  The series in mm.git breaks the
s390 build.
