From dd5ac03e09554b7504f64990cfbcec884e3ec430 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Wed, 30 Nov 2016 19:41:02 +1100 Subject: [PATCH] powerpc/mm: Fix page table dump build on non-Book3S In the recent commit 1515ab932156 ("powerpc/mm: Dump hash table") we added code to dump the hage page table. Currently this can be selected to build on any platform. However it breaks the build if we're building for a non-Book3S platform, because none of the hash page table related defines and so on exist. So restrict it to building only on Book3S. Similarly in commit 8eb07b187000 ("powerpc/mm: Dump linux pagetables") we added code to dump the Linux page tables, which uses some constants which are only defined on Book3S - so guard those with an #ifdef.
