Hmm, maybe my tree is missing some follow up fix but git diff sees nothin relevant. Neverheless I have noticed that both CONFIG_SWAP and CONFIG_NFS_SWAP are disabled. get_kernel_page is defined in mm/swap.c but that one should be compiled in regardless the SWAP configuration. I do not see this error on x86_64 with the above two disabled. Is it possible that this is something m32r specific? Possibly some confusion wrt.
