From: Jan Höppner <hoeppner@linux.ibm.com>

Printing pointer in error messages doesn't add any value since the
addresses are hashed. Remove the %p format specifier and adapt the error
messages slightly.

Replace %p with %px in ERP to get the actual addresses since ERP is used
for debugging purposes only anyway.
