https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=03aa047ef2db4985e444af6ee1c1dd084ad9fb4c s390/early: improve machine detection Right now the early machine detection code check stsi 3.2.2 for "KVM" and set MACHINE_IS_VM if this is different. As the console detection uses diagnose 8 if MACHINE_IS_VM returns true this will crash Linux early for any non z/VM system that sets a different value than KVM. So instead of assuming z/VM, do not set any of MACHINE_IS_LPAR, MACHINE_IS_VM, or MACHINE_IS_KVM.
