Most platforms ignore parameter provided to ZERO_PAGE macro,
hence wrong parameter was used and missed. This caused to compilation
error like presented below.
drivers/infiniband/core/uverbs_main.c: In function 'rdma_umap_fault':
drivers/infiniband/core/uverbs_main.c:898:28: error: 'struct vm_fault' has no member named 'vm_start'
vmf->page = ZERO_PAGE(vmf->vm_start);
