	  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.

# OK, it's a little counter-intuitive to do this, but it puts it neatly under
# the virtualization menu.
