[Crash-utility] [PATCH] s390x: Implement swap PTE for kernel 3.12

[Michael Holzheu]

Hi Dave,

The following kernel git commit changes swap PTEs again
for Linux 3.12:

commit e509861105a3c1425f3f929bd631f88340b499bf
Author: Martin Schwidefsky <schwidefsky at de.ibm.com>
Date:   Tue Jul 23 20:57:57 2013 +0200

    s390/mm: cleanup page table definitions

So we have to do this also in crash.
