From b07ce24df7fee54189a7bca583bcda81a5448198 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 29 Jul 2024 23:44:59 +0200 Subject: alpha: fix ioread64be()/iowrite64be() helpers Compile-testing the crypto/caam driver on alpha showed a pre-existing problem on alpha with iowrite64be() missing: ERROR: modpost: "iowrite64be" [drivers/crypto/caam/caam_jr.ko] undefined! The prototypes were added a while ago when we started using asm-generic/io.h, but the implementation was still missing. At some point the ioread64/iowrite64 helpers were added, but the big-endian versions are still missing, and the generic version (using readq/writeq) is would not work here. Change it to wrap ioread64()/iowrite64() instead. Fixes: beba3771d9e0 ("crypto: caam: Make CRYPTO_DEV_FSL_CAAM dependent of COMPILE_TEST") Fixes: e19d4ebc536d ("alpha: add full ioread64/iowrite64 implementation") Fixes: 7e772dad9913 ("alpha: Use generic ") Closes: https://lore.kernel.org/all/CAHk-=wgEyzSxTs467NDOVfBSzWvUS6ztcwhiy=M3xog==KBmTw@mail.gmail.com/ Tested-by: Guenter Roeck Reviewed-by: Linus Walleij Signed-off-by: Arnd Bergmann --- arch/alpha/include/asm/io.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'arch') diff --git a/arch/alpha/include/asm/io.h b/arch/alpha/include/asm/io.h index 2bb8cbeedf91..b191d87f89c4 100644 --- a/arch/alpha/include/asm/io.h +++ b/arch/alpha/include/asm/io.h @@ -534,8 +534,10 @@ extern inline void writeq(u64 b, volatile void __iomem *addr) #define ioread16be(p) swab16(ioread16(p)) #define ioread32be(p) swab32(ioread32(p)) +#define ioread64be(p) swab64(ioread64(p)) #define iowrite16be(v,p) iowrite16(swab16(v), (p)) #define iowrite32be(v,p) iowrite32(swab32(v), (p)) +#define iowrite64be(v,p) iowrite64(swab64(v), (p)) #define inb_p inb #define inw_p inw @@ -634,8 +636,6 @@ extern void outsl (unsigned long port, const void *src, unsigned long count); */ #define ioread64 ioread64 #define iowrite64 iowrite64 -#define ioread64be ioread64be -#define iowrite64be iowrite64be #define ioread8_rep ioread8_rep #define ioread16_rep ioread16_rep #define ioread32_rep ioread32_rep -- cgit v1.2.3
