From f1ab428711358fbb747ba392c3448462494e6c6a Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Wed, 9 Sep 2015 18:22:35 +1000 Subject: crypto: vmx - VMX crypto should depend on CONFIG_VSX This code uses FP (floating point), Altivec and VSX (Vector-Scalar Extension). It can just depend on CONFIG_VSX though, because that already depends on FP and Altivec. Otherwise we get lots of link errors such as: drivers/built-in.o: In function `.p8_aes_setkey': aes.c:(.text+0x2d325c): undefined reference to `.enable_kernel_altivec' aes.c:(.text+0x2d326c): undefined reference to `.enable_kernel_vsx' Signed-off-by: Michael Ellerman Signed-off-by: Herbert Xu --- drivers/crypto/Kconfig | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/crypto/Kconfig b/drivers/crypto/Kconfig index 07bc7aa..d234719 100644 --- a/drivers/crypto/Kconfig +++ b/drivers/crypto/Kconfig @@ -461,7 +461,7 @@ config CRYPTO_DEV_QCE config CRYPTO_DEV_VMX bool "Support for VMX cryptographic acceleration instructions" - depends on PPC64 + depends on PPC64 && VSX help Support for VMX cryptographic acceleration instructions. -- cgit v1.1 From 9da75de030bb6e49475ef37c8495d07e98cfeb33 Mon Sep 17 00:00:00 2001 From: LABBE Corentin Date: Wed, 9 Sep 2015 14:27:07 +0200 Subject: crypto: sunxi-ss - Fix a possible driver hang with ciphers The sun4i_ss_opti_poll function cipher data until the output miter have a length of 0.
