From 61abc356bf310d346d2d469cb009f6d4334f34de Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Fri, 29 Mar 2019 17:46:29 -0700 Subject: crypto: aes - Use ___cacheline_aligned for aes data cacheline_aligned is a special section. It cannot be const at the same time because it's not read-only. It doesn't give any MMU protection. Mark it ____cacheline_aligned to not place it in a special section, but just align it in .rodata Cc: herbert@gondor.apana.org.au Suggested-by: Rasmus Villemoes Signed-off-by: Andi Kleen Acked-by: Ard Biesheuvel Signed-off-by: Herbert Xu --- crypto/aes_generic.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'crypto') diff --git a/crypto/aes_generic.c b/crypto/aes_generic.c index 13df33aca463..fddcbe3edb0a 100644 --- a/crypto/aes_generic.c +++ b/crypto/aes_generic.c @@ -64,7 +64,7 @@ static inline u8 byte(const u32 x, const unsigned n) static const u32 rco_tab[10] = { 1, 2, 4, 8, 16, 32, 64, 128, 27, 54 }; /* cacheline-aligned to facilitate prefetching into cache */ -__visible const u32 crypto_ft_tab[4][256] __cacheline_aligned = { +__visible const u32 crypto_ft_tab[4][256] ____cacheline_aligned = { { 0xa56363c6, 0x847c7cf8, 0x997777ee, 0x8d7b7bf6, 0x0df2f2ff, 0xbd6b6bd6, 0xb16f6fde, 0x54c5c591, @@ -328,7 +328,7 @@ __visible const u32 crypto_ft_tab[4][256] __cacheline_aligned = { } }; -__visible const u32 crypto_fl_tab[4][256] __cacheline_aligned = { +__visible const u32 crypto_fl_tab[4][256] ____cacheline_aligned = { { 0x00000063, 0x0000007c, 0x00000077, 0x0000007b, 0x000000f2, 0x0000006b, 0x0000006f, 0x000000c5, @@ -592,7 +592,7 @@ __visible const u32 crypto_fl_tab[4][256] __cacheline_aligned = { } }; -__visible const u32 crypto_it_tab[4][256] __cacheline_aligned = { +__visible const u32 crypto_it_tab[4][256] ____cacheline_aligned = { { 0x50a7f451, 0x5365417e, 0xc3a4171a, 0x965e273a, 0xcb6bab3b, 0xf1459d1f, 0xab58faac, 0x9303e34b, @@ -856,7 +856,7 @@ __visible const u32 crypto_it_tab[4][256] __cacheline_aligned = { } }; -__visible const u32 crypto_il_tab[4][256] __cacheline_aligned = { +__visible const u32 crypto_il_tab[4][256] ____cacheline_aligned = { { 0x00000052, 0x00000009, 0x0000006a, 0x000000d5, 0x00000030, 0x00000036, 0x000000a5, 0x00000038, -- cgit v1.2.3-59-g8ed1b
