A variety of one-off changes... The following changes since commit e9e60c82fe391d04db55a91c733df4a017c28b2f: selftests/kvm: fix compilation on non-x86_64 platforms (2023-11-21 11:58:25 -0500) are available in the Git repository at: https://github.com/kvm-x86/linux.git tags/kvm-x86-misc-6.8 for you to fetch changes up to 15223c4f973a6120665ece9ce1ad17aec0be0e6c: KVM: SVM,VMX: Use %rip-relative addressing to access kvm_rebooting (2023-11-30 12:51:54 -0800) ---------------------------------------------------------------- KVM x86 misc changes for 6.8: - Turn off KVM_WERROR by default for all configs so that it's not inadvertantly enabled by non-KVM developers, which can be problematic for subsystems that require no regressions for W=1 builds. - Advertise all of the host-supported CPUID bits that enumerate IA32_SPEC_CTRL "features". - Don't force a masterclock update when a vCPU synchronizes to the current TSC generation, as updating the masterclock can cause kvmclock's time to "jump" unexpectedly, e.g. when userspace hotplugs a pre-created vCPU. - Use RIP-relative address to read kvm_rebooting in the VM-Enter fault paths, partly as a super minor optimization, but mostly to make KVM play nice with position independent executable builds. ---------------------------------------------------------------- Jim Mattson (2): KVM: x86: Advertise CPUID.(EAX=7,ECX=2):EDX[5:0] to userspace KVM: x86: Use a switch statement and macros in __feature_translate() Sean Christopherson (2): KVM: x86: Turn off KVM_WERROR by default for all configs KVM: x86: Don't unnecessarily force masterclock update on vCPU hotplug Uros Bizjak (1): KVM: SVM,VMX: Use %rip-relative addressing to access kvm_rebooting arch/x86/kvm/Kconfig | 14 +++++++------- arch/x86/kvm/cpuid.c | 21 ++++++++++++++++++--- arch/x86/kvm/reverse_cpuid.h | 33 ++++++++++++++++++++++----------- arch/x86/kvm/svm/vmenter.S | 10 +++++----- arch/x86/kvm/vmx/vmenter.S | 2 +- arch/x86/kvm/x86.c | 29 ++++++++++++++++------------- 6 files changed, 69 insertions(+), 40 deletions(-)
