Thanks for the report. > Hi, This commit broke my build in a similar way: make ARCH=x86_64 O=../linux-tdx-kvm-out/ -j36 M=arch/x86/kvm/ make[1]: Entering directory '/home/rpedgeco/repos/linux-tdx-kvm-out' /home/rpedgeco/repos/linux/scripts/Makefile.build:41: arch/x86/kvm/Makefile: No such file or directory make[3]: *** No rule to make target 'arch/x86/kvm/Makefile'.

I'm guess it has something to do with the "M=" option because: make ARCH=x86_64 O=../linux-tdx-kvm-out/ -j36 arch/x86/kvm/kvm.ko arch/x86/kvm/kvm-intel.ko ...works.
