[PATCH v4 0/2] mm: add vmalloc_no_huge and use it

[Claudio Imbrenda <imbrenda@xxxxxxxxxxxxx>]

Add vmalloc_no_huge and export it, so modules can allocate memory with
small pages.

Use the newly added vmalloc_no_huge in KVM on s390 to get around a
hardware limitation.

v3->v4:
* reword commit messages to be more clear
* add comment in the second patch

v2->v3:
* do not export __vmalloc_node_range
* add vmalloc_no_huge as a wrapper around __vmalloc_node_range
* use vmalloc_no_huge instead of __vmalloc_node_range in kvm on s390x
