Subject: Problems with phys_to_pfn_t in linux-next and s390
Date: Wed, 23 Dec 2015 21:56:57 -0800	[thread overview]
Message-ID: <567B8929.1060207@roeck-us.net> (raw)

s390:defconfig:

ERROR: "phys_to_pfn_t" [drivers/s390/block/dcssblk.ko] undefined!

s390 does not set CONFIG_HAS_IOMEM, which is required for phys_to_pfn_t to exist.

Introduced with commit e014f77c4b ("mm-dax-pmem-introduce-pfn_t-v3") and
possibly earlier.
