linux-next: hwpoison tree build failure

From: Stephen Rothwell

Hi Andi,

Today's linux-next build (x86_64 allmodconfig) failed like this:

mm/memory-failure.c: In function 'soft_offline_page':
mm/memory-failure.c:1266: error: too few arguments to function 'migrate_pages'

Caused by commit c71d409184af558ddac0fd0167061d6282428872 ("HWPOISON: Add
soft page offline support") from the hwpoison tree interacting with
commit 62b61f611eb5e20f7e9f8619bfd03bdfe8af6348 ("ksm: memory hotremove
migration only") from Linus' tree.

I added the following merge fix for today (I don't know if it is correct)
and can carry it for a while:
