[PATCH 3.16 007/133] powerpc/mm: Build fix for non SPARSEMEM_VMEMAP config

From: Ben Hutchings
Date: Tue Nov 21 2017 - 21:21:47 EST


3.16.51-rc1 review patch. If anyone has any objections, please let me know.

------------------

From: "Aneesh Kumar K.V" <aneesh.kumar@xxxxxxxxxxxxxxxxxx>

commit 7e7dc66adcf490a619bc3c7763a8cebadfba73e3 upstream.

We can use pfn_to_page() in realmode for other configs. Hence remove the
CONFIG_FLATMEM ifdef.

Fixes: 8e0861fa3c4e ("powerpc: Prepare to support kernel handling of IOMMU map/unmap")
