Alexander Graf a725d56a02 KVM: Introduce CONFIG_HAVE_KVM_IRQ_ROUTING
Quite a bit of code in KVM has been conditionalized on availability of
IOAPIC emulation. However, most of it is generically applicable to
platforms that don't have an IOPIC, but a different type of irq chip.

Make code that only relies on IRQ routing, not an APIC itself, on
CONFIG_HAVE_KVM_IRQ_ROUTING, so that we can reuse it later.

---help---
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 fully virtualized guest machines using hardware
virtualization extensions. You will need a fairly recent
processor equipped with virtualization extensions. You will also
need to select one or more of the processor modules below.
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.

# for perf_guest_get_msrs():

---help---
Provides support for KVM on Intel processors equipped with the VT
extensions.
To compile this as a module, choose M here: the module
will be called kvm-intel.
config KVM_AMD
tristate "KVM for AMD processors support"
depends on KVM
---help---
Provides support for KVM on AMD processors equipped with the AMD-V
(SVM) extensions.
To compile this as a module, choose M here: the module
will be called kvm-amd.
config KVM_MMU_AUDIT
bool "Audit KVM MMU"
depends on KVM && TRACEPOINTS
---help---
This option adds a R/W kVM module parameter 'mmu_audit', which allows
audit KVM MMU at runtime.
# OK, it's a little counter-intuitive to do this, but it puts it neatly under
# the virtualization menu.
