And it also forces CRYPTO_GHASH to be builtin even CRYPTO_DEV_VMX_ENCRYPT was configured as module. This requires to change defconfig values to m for backwards compatibility. Signed-off-by: Petr Vorel --- changes v2->v3: * keep CRYPTO_DEV_VMX and merge CRYPTO_DEV_VMX_ENCRYPT into it instead of vice versa (suggested by Nicolai). I have no problem to send another version if maintainers want the original approach. * change commit subject to be compatible * remove MAINTAINERS changes arch/powerpc/configs/powernv_defconfig | 2 +- arch/powerpc/configs/ppc64_defconfig | 2 +- arch/powerpc/configs/pseries_defconfig | 2 +- drivers/crypto/Kconfig | 9 +++++---- drivers/crypto/vmx/Kconfig | 10 ---------- drivers/crypto/vmx/Makefile | 4 ++-- 6 files changed, 10 insertions(+), 19 deletions(-) delete mode 100644 drivers/crypto/vmx/Kconfig diff --git a/arch/powerpc/configs/powernv_defconfig b/arch/powerpc/configs/powernv_defconfig index 49f49c263935..661b294d1744 100644 --- a/arch/powerpc/configs/powernv_defconfig +++ b/arch/powerpc/configs/powernv_defconfig @@ -337,7 +337,7 @@ CONFIG_CRYPTO_TEA=m CONFIG_CRYPTO_TWOFISH=m CONFIG_CRYPTO_LZO=m CONFIG_CRYPTO_DEV_NX=y -CONFIG_CRYPTO_DEV_VMX=y +CONFIG_CRYPTO_DEV_VMX=m CONFIG_VIRTUALIZATION=y CONFIG_KVM_BOOK3S_64=m CONFIG_KVM_BOOK3S_64_HV=m diff --git a/arch/powerpc/configs/ppc64_defconfig b/arch/powerpc/configs/ppc64_defconfig index c8b0e80d613b..cc51b506066c 100644 --- a/arch/powerpc/configs/ppc64_defconfig +++ b/arch/powerpc/configs/ppc64_defconfig @@ -355,7 +355,7 @@ CONFIG_CRYPTO_TWOFISH=m CONFIG_CRYPTO_LZO=m CONFIG_CRYPTO_DEV_NX=y CONFIG_CRYPTO_DEV_NX_ENCRYPT=m -CONFIG_CRYPTO_DEV_VMX=y +CONFIG_CRYPTO_DEV_VMX=m CONFIG_PRINTK_TIME=y CONFIG_PRINTK_CALLER=y CONFIG_MAGIC_SYSRQ=y diff --git a/arch/powerpc/configs/pseries_defconfig b/arch/powerpc/configs/pseries_defconfig index b571d084c148..2366d3be0d11 100644 --- a/arch/powerpc/configs/pseries_defconfig +++ b/arch/powerpc/configs/pseries_defconfig @@ -315,7 +315,7 @@ CONFIG_CRYPTO_TWOFISH=m CONFIG_CRYPTO_LZO=m CONFIG_CRYPTO_DEV_NX=y CONFIG_CRYPTO_DEV_NX_ENCRYPT=m -CONFIG_CRYPTO_DEV_VMX=y +CONFIG_CRYPTO_DEV_VMX=m CONFIG_VIRTUALIZATION=y CONFIG_KVM_BOOK3S_64=m CONFIG_KVM_BOOK3S_64_HV=m diff --git a/drivers/crypto/Kconfig b/drivers/crypto/Kconfig index 4f705674f94f..923fa1effb4a 100644 --- a/drivers/crypto/Kconfig +++ b/drivers/crypto/Kconfig @@ -762,12 +762,13 @@ config CRYPTO_DEV_QCOM_RNG module will be called qcom-rng.
