This is a partial header to get the KVM_ARM_GET_MAX_VM_PHYS_SHIFT ioctl. 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 <eric.auger@redhat.com> --- 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(-)
