Claudio Imbrenda 185cca24e9 KVM: s390: prepare for hugepage vmalloc 
The Create Secure Configuration Ultravisor Call does not support using
large pages for the virtual memory area.  This is a hardware limitation.

This patch replaces the vzalloc call with an almost equivalent call to
the newly introduced vmalloc_no_huge function, which guarantees that
only small pages will be used for the backing.

The new call will not clear the allocated memory, but that has never
been an actual requirement.
