Carsten Otte e08b963716 KVM: s390: add parameter for KVM_CREATE_VM
This patch introduces a new config option for user controlled kernel
virtual machines. It introduces a parameter to KVM_CREATE_VM that
allows to set bits that alter the capabilities of the newly created
virtual machine.
The parameter is passed to kvm_arch_init_vm for all architectures.
The only valid modifier bit for now is KVM_VM_S390_UCONTROL.
This requires CAP_SYS_ADMIN privileges and creates a user controlled
virtual machine on s390 architectures.

Say Y here to get to see options for using your Linux host to run other
operating systems inside virtual machines (guests).
This option alone does not add any kernel code.
If you say N, all options in this submenu will be skipped and disabled.

---help---
Support hosting paravirtualized guest machines using the SIE
virtualization capability on the mainframe. This should work
on any 64bit machine.
This module provides access to the hardware capabilities through
a character device node named /dev/kvm.
To compile this as a module, choose M here: the module
will be called kvm.
If unsure, say N.

bool "Userspace controlled virtual machines"

---help---
Allow CAP_SYS_ADMIN users to create KVM virtual machines that are
controlled by userspace.
If unsure, say N.
# OK, it's a little counter-intuitive to do this, but it puts it neatly under
# the virtualization menu.
