Subject: fix for "virsh dump" dumps with KASLR
Patch-mainline: 7.2.6
Git-commit: 5aa3c1da3e22037aeeca8d745cec1481137c79fe

Fix for determining the x86_64 "phys_base" value in dumpfiles created
by the KVM "virsh dump" facility if the kernel is KASLR-enabled and
does not have the phys_base value stored in vmcoreinfo data.  Without
the patch, the message "WARNING: cannot determine physical base
address: defaulting to 0" is displayed, and the crash session fails
to initialize.
