[PATCH] hwpoison: fix uninitialized warning

From: Hugh Dickins
Date: Tue Sep 15 2009 - 17:20:11 EST


Fix mmotm build warning, presumably also in linux-next:
mm/memory.c: In function `do_swap_page':
mm/memory.c:2498: warning: `pte' may be used uninitialized in this function

I've only noticed this warning on one machine, the powerpc: certainly it
needs CONFIG_MIGRATION or CONFIG_MEMORY_FAILURE to see it, but I thought
I had one of those set on other machines - just musing in case it's being
masked elsewhere by some other bug...
