Subject: [PATCH] powerpc/powernv/ioda: Finish removing explicit max window
size check
References: bsc#1061840
Patch-mainline: v4.16-rc1
Git-commit: ae677ff02f2ddb0980953efd4afed1c90a56c88f
9003a2498 removed checn from the DMA window pages allocator, however
the VFIO driver tests limits before doing so by calling
the get_table_size hook which was left behind; this fixes it.
