KVM: s390: Change guestaddr type in gaccess
All registers are unsigned long types. This patch changes all occurences of guestaddr in gaccess from u64 to unsigned long. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com> Signed-off-by: Christian Borntraeger <borntraeger@de.ibm.com> Signed-off-by: Avi Kivity <avi@qumranet.com>
