I cherry-picked the basic, x86 and mips patches to kvm.git's master > branch (I did not use your branch in order to leave arm64 and riscv to the > respective maintainers). Since everything's dependent upon that core patch, IIUC that's going to make it a pain for them to queue things. How are you expecting the arm64 and riscv maintainers to queue things? Queue their own copies of that core patch?
