From: Logan Gunthorpe Subject: [PATCH v5 2/6] powerpc: iomap.c: introduce io{read|write}64_{lo_hi|hi_lo} Date: Wed, 26 Jul 2017 17:19:13 -0600 Message-ID: <20170726231917.6073-3-logang@deltatee.com> References: <20170726231917.6073-1-logang@deltatee.com> Cc: Arnd Bergmann , Greg Kroah-Hartman , =?UTF-8?q?Horia=20Geant=C4=83?= , Stephen Bates , Logan Gunthorpe To: linux-kernel@vger.kernel.org, linux-arch@vger.kernel.org, linux-ntb@googlegroups.com, linux-crypto@vger.kernel.org Return-path: Received: from ale.deltatee.com ([207.54.116.67]:41391 "EHLO ale.deltatee.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1751078AbdGZXTX (ORCPT ); Wed, 26 Jul 2017 19:19:23 -0400 In-Reply-To: <20170726231917.6073-1-logang@deltatee.com> Sender: linux-crypto-owner@vger.kernel.org List-ID: These functions will be introduced into the generic iomap.c so they can deal with PIO accesses in hi-lo/lo-hi variants. Thus, the powerpc version of iomap.c will need to provide the same functions even though, in this arch, they are identical to the regular io{read|write}64 functions. --- arch/powerpc/kernel/iomap.c | 40 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 40 insertions(+) diff --git a/arch/powerpc/kernel/iomap.c b/arch/powerpc/kernel/iomap.c index a1854d1ded8b..b43dbadfd24f 100644 --- a/arch/powerpc/kernel/iomap.c +++ b/arch/powerpc/kernel/iomap.c @@ -44,12 +44,32 @@ u64 ioread64(void __iomem *addr) { return readq(addr); } +u64 ioread64_lo_hi(void __iomem *addr) +{ + return readq(addr); +} +u64 ioread64_hi_lo(void __iomem *addr) +{ + return readq(addr); +} u64 ioread64be(void __iomem *addr) { return readq_be(addr); } +u64 ioread64be_lo_hi(void __iomem *addr) +{ + return readq_be(addr); +} +u64 ioread64be_hi_lo(void __iomem *addr) +{ + return readq_be(addr); +} EXPORT_SYMBOL(ioread64); +EXPORT_SYMBOL(ioread64_lo_hi); +EXPORT_SYMBOL(ioread64_hi_lo); EXPORT_SYMBOL(ioread64be); +EXPORT_SYMBOL(ioread64be_lo_hi); +EXPORT_SYMBOL(ioread64be_hi_lo); #endif /* __powerpc64__ */ void iowrite8(u8 val, void __iomem *addr) @@ -82,12 +102,32 @@ void iowrite64(u64 val, void __iomem *addr) { writeq(val, addr); } +void iowrite64_lo_hi(u64 val, void __iomem *addr) +{ + writeq(val, addr); +} +void iowrite64_hi_lo(u64 val, void __iomem *addr) +{ + writeq(val, addr); +} void iowrite64be(u64 val, void __iomem *addr) { writeq_be(val, addr); } +void iowrite64be_lo_hi(u64 val, void __iomem *addr) +{ + writeq_be(val, addr); +} +void iowrite64be_hi_lo(u64 val, void __iomem *addr) +{ + writeq_be(val, addr); +} EXPORT_SYMBOL(iowrite64); +EXPORT_SYMBOL(iowrite64_lo_hi); +EXPORT_SYMBOL(iowrite64_hi_lo); EXPORT_SYMBOL(iowrite64be); +EXPORT_SYMBOL(iowrite64be_lo_hi); +EXPORT_SYMBOL(iowrite64be_hi_lo); #endif /* __powerpc64__ */ /* -- 2.11.0
