Subject: [PATCH 0/2] KVM: s390: Don't use %pK through debug printing or
 tracepoints

Restricted pointers ("%pK") are only meant to be used when directly
printing to a file from task context.
Otherwise it can unintentionally expose security sensitive, raw pointer values.

Use regular pointer formatting instead.
