Introduce a new interrupt class for s390 adapter interrupts and enable irqfds for s390. This is depending on a new s390 specific vm capability, KVM_CAP_S390_IRQCHIP, that needs to be enabled by userspace.

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.
