Commit 480b6837aa57 "nvdimm: fix PHYS_PFN/PFN_PHYS mixup" identified that we were passing an invalid address to devm_nvdimm_ioremap(). With that fixed it exposed a bug in the memory reservation size for flush hint tables. Since we map a full page we need to mock a full page of memory to back the flush hint table entries.
