alpha:allmodconfig fails to build with the following error.
drivers/nvdimm/pmem.c: In function 'nd_pfn_init': drivers/nvdimm/pmem.c:407:17: error: 'HPAGE_SIZE' undeclared
Problem is due to commit 658922e57b84 ("libnvdimm, pfn: fix memmap reservation sizing").
HPAGE_SIZE is not defined for all architectures and was up to now not used in driver code. All other architectures with 64 bit physical address provide the definition, though, as far as I can see, so it may be that only alpha is affected.
Since stable is copied - this will also result in stable build errors if applied to -stable branches.
