Subject: [PATCH kernel 02/10] powerpc/powernv: Rename pnv_pci_ioda2_tce_invalidate_entire
Date: Wed, 9 Mar 2016 17:28:58 +1100 [thread overview]
Message-ID: <1457504946-40649-3-git-send-email-aik@ozlabs.ru> (raw)
In-Reply-To: <1457504946-40649-1-git-send-email-aik@ozlabs.ru>
As in fact pnv_pci_ioda2_tce_invalidate_entire() invalidates TCEs for
the specific PE rather than the entire cache, rename it to
pnv_pci_ioda2_tce_invalidate_pe(). In later patches we will add
a proper pnv_pci_ioda2_tce_invalidate_entire().
