Subject: linux-next: build failure after merge of the powerpc tree

---

Hi all,

After merging the powerpc tree, today's linux-next build (powerpc
allyesconfig) failed like this:

make[4]: *** No rule to make target 'arch/powerpc/mm/ptdump/core.o', needed by 'arch/powerpc/mm/ptdump/built-in.a'.

Caused by commit

5df1cfa43394 ("powerpc: Move page table dump files in a dedicated subdirectory")

I have reverted that commit for today.

Cheers,
Stephen Rothwell

In the Makefile, replace core.o by ptdump.o (or rename the file ptdump.c
to core.c). Michael, what was your intention ?

To not break the build :}

I originally used core.c but then decided ptdump.c was clearer.

My jenkins was unhappy last night due to a distro upgrade so my builds
didn't run and catch the breakage.

I'll just fix it and force push.

cheers
