Subject: [PATCH 1/3] powerpc: export cpu_to_chip_id
Date: Tue, 10 Sep 2013 18:38:55 +0200 [thread overview]
Message-ID: <1378831135-2179-1-git-send-email-murzin.v@gmail.com> (raw)
While cross-building for PPC64 I've got
ERROR: ".cpu_to_chip_id" [drivers/block/mtip32xx/mtip32xx.ko] undefined!
mtip32xx refer to topology_physical_package_id, which stands for
cpu_to_chip-id.
Make cpu_to_chip-id (and topology_physical_package_id) available for
external users.
