Subject: linux-next: build failure
Date: Fri, 25 Jul 2008 16:45:33 +1000 [thread overview]
Message-ID: <20080725164533.808c209a.sfr@canb.auug.org.au> (raw)
Hi all,
Today's linux-next build (powerpc ppc44x_config) failed like this:
mm/migrate.c: In function 'remove_migration_pte':
mm/migrate.c:195: error: implicit declaration of function 'update_mmu_cache'
I applied the patch below from Benjamin Herrenschmidt (which he will send
to Linus).

where it belongs. This fixes some build problems on some configs
