commit 0139aa7b7fa1 ("mm: rename _count, field of the struct page, to _refcount") changed all accesses to page->_count to use wrappers. There is already a page_ref_dec_return and we need for kvm/s390 code the function "page_ref_inc_return" as well. FWIW, the code is under https://git.kernel.org/cgit/linux/kernel/git/kvms390/linux.git/log/?h=next Can I get an ack to carry this patch via the KVM/s390 tree (will be merged into Paolos kvm tree soon)?
