This allows to retrieve the IPA address range KVM supports. This is based on branch: https://github.com/eauger/linux/tree/4.16.0-rc3-Suzuki-52b-IPA-v2 itself derived from Suzuki's branch (just incremented the IOCTL index) git://linux-arm.org/linux-skp.git ipa52/v2 Signed-off-by: Eric Auger --- linux-headers/asm-arm/kvm.h | 15 --------------- linux-headers/asm-arm64/kvm.h | 6 ------ linux-headers/linux/kvm.h | 6 ++++++ 3 files changed, 6 insertions(+), 21 deletions(-) diff --git a/linux-headers/asm-arm/kvm.h b/linux-headers/asm-arm/kvm.h index 670b43c..4392955 100644 --- a/linux-headers/asm-arm/kvm.h +++ b/linux-headers/asm-arm/kvm.h @@ -135,15 +135,6 @@ struct kvm_arch_memory_slot { #define KVM_REG_ARM_CRM_SHIFT 7 #define KVM_REG_ARM_32_CRN_MASK 0x0000000000007800 #define KVM_REG_ARM_32_CRN_SHIFT 11 -/* - * For KVM currently all guest registers are nonsecure, but we reserve a bit - * in the encoding to distinguish secure from nonsecure for AArch32 system - * registers that are banked by security.
