Subject[PATCH] block: pmem: Add dependency on HAS_IOMEM
Date
Not all architectures have io memory.

Fixes:
drivers/block/pmem.c: In function ‘pmem_alloc’:
drivers/block/pmem.c:146:2: error: implicit declaration of function ‘ioremap_nocache’ [-Werror=implicit-function-declaration]
pmem->virt_addr = ioremap_nocache(pmem->phys_addr, pmem->size);
^
drivers/block/pmem.c:146:18: warning: assignment makes pointer from integer without a cast [enabled by default]
pmem->virt_addr = ioremap_nocache(pmem->phys_addr, pmem->size);
^
drivers/block/pmem.c:182:2: error: implicit declaration of function ‘iounmap’ [-Werror=implicit-function-declaration]
iounmap(pmem->virt_addr);
^

Saying Y here will allow you to use a contiguous range of reserved
memory as one or more persistent block devices.
