Hi all, After merging the kvm tree, today's linux-next build (x86_64 allmodconfig) failed like this: In file included from include/linux/kvm_host.h:38, from arch/x86/kvm/../../../virt/kvm/coalesced_mmio.c:14: arch/x86/include/asm/kvm_host.h:38:10: fatal error: asm/kvm_vcpu_regs.h: No such file or directory #include ^~~~~~~~~~~~~~~~~~~~~ In file included from include/linux/kvm_host.h:38, from arch/x86/kvm/../../../virt/kvm/kvm_main.c:21: arch/x86/include/asm/kvm_host.h:38:10: fatal error: asm/kvm_vcpu_regs.h: No such file or directory #include ^~~~~~~~~~~~~~~~~~~~~ In file included from include/linux/kvm_host.h:38, from arch/x86/kvm/../../../virt/kvm/eventfd.c:24: arch/x86/include/asm/kvm_host.h:38:10: fatal error: asm/kvm_vcpu_regs.h: No such file or directory #include ^~~~~~~~~~~~~~~~~~~~~ In file included from include/linux/kvm_host.h:38, from arch/x86/kvm/../../../virt/kvm/irqchip.c:27: arch/x86/include/asm/kvm_host.h:38:10: fatal error: asm/kvm_vcpu_regs.h: No such file or directory #include ^~~~~~~~~~~~~~~~~~~~~ In file included from include/linux/kvm_host.h:38, from arch/x86/kvm/../../../virt/kvm/async_pf.c:23: arch/x86/include/asm/kvm_host.h:38:10: fatal error: asm/kvm_vcpu_regs.h: No such file or directory #include ^~~~~~~~~~~~~~~~~~~~~ In file included from include/linux/kvm_host.h:38, from arch/x86/kvm/../../../virt/kvm/vfio.c:14: arch/x86/include/asm/kvm_host.h:38:10: fatal error: asm/kvm_vcpu_regs.h: No such file or directory #include ^~~~~~~~~~~~~~~~~~~~~ In file included from include/linux/kvm_host.h:38, from arch/x86/kvm/x86.c:22: arch/x86/include/asm/kvm_host.h:38:10: fatal error: asm/kvm_vcpu_regs.h: No such file or directory #include ^~~~~~~~~~~~~~~~~~~~~ In file included from include/linux/kvm_host.h:38, from arch/x86/kvm/irq.h:27, from arch/x86/kvm/mmu.c:21: arch/x86/include/asm/kvm_host.h:38:10: fatal error: asm/kvm_vcpu_regs.h: No such file or directory #include ^~~~~~~~~~~~~~~~~~~~~ In file included from include/linux/kvm_host.h:38, from arch/x86/kvm/emulate.c:23: arch/x86/include/asm/kvm_host.h:38:10: fatal error: asm/kvm_vcpu_regs.h: No such file or directory #include ^~~~~~~~~~~~~~~~~~~~~ In file included from include/linux/kvm_host.h:38, from drivers/gpu/drm/i915/gvt/kvmgt.c:42: arch/x86/include/asm/kvm_host.h:38:10: fatal error: asm/kvm_vcpu_regs.h: No such file or directory #include ^~~~~~~~~~~~~~~~~~~~~ Caused by commits 1561fcbc8e16 ("KVM: x86: Explicitly #define the VCPU_REGS_* indices") a46e726511f4 ("KVM: VMX: Move vCPU-run code to a proper assembly routine") It looks like a file was not git added :-( I have used the kvm tree from next-20190215 for today. -- Cheers, Stephen Rothwell
