fa3d315a "KVM: Validate userspace_addr of memslot when registered" introduced
this new warning onn s390:
kvm_main.c: In function '__kvm_set_memory_region':
kvm_main.c:654:7: warning: passing argument 1 of '__access_ok' makes pointer
from integer without a cast
arch/s390/include/asm/uaccess.h:53:19: note: expected 'const void *' but
argument is of type '__u64'
Add the missing cast to get rid of it again...
