make selecting between the two models easier.

bool
menuconfig VIRTUALIZATION
bool "Virtualization"
---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.

config KVM_440
bool "KVM support for PowerPC 440 processors"
depends on EXPERIMENTAL && 44x
select KVM
---help---
Support running unmodified 440 guest kernels in virtual machines on
440 host processors.
This module provides access to the hardware capabilities through
a character device node named /dev/kvm.
If unsure, say N.
config KVM_EXIT_TIMING
bool "Detailed exit timing"
depends on KVM
---help---
Calculate elapsed time for every exit/enter cycle. A per-vcpu
report is available in debugfs kvm/vm#_vcpu#_timing.
The overhead is relatively small, however it is not recommended for
production environments.
If unsure, say N.
config KVM_E500
bool "KVM support for PowerPC E500 processors"
depends on EXPERIMENTAL && E500
select KVM
---help---
Support running unmodified E500 guest kernels in virtual machines on
E500 host processors.
This module provides access to the hardware capabilities through
a character device node named /dev/kvm.
If unsure, say N.

bool "KVM trace support"
depends on KVM && MARKERS && SYSFS
select RELAY
select DEBUG_FS
default n
---help---
This option allows reading a trace of kvm-related events through
relayfs. Note the ABI is not considered stable and will be
modified in future updates.
