Your customers are not concervative at all if they are consuming the
RETBLEED and other Spectre-like fixes into your kernels.  Those are
major changes as you can see (affecting every single file you build), so
the "do not change anything" argument does not make any sense here,
right?

That's great, but some help in fixing this reported issue would also be
most appreciated, as you are the best one to test and verify the fix.
