Subject: [PATCH] KVM: kvm/ia64: select ANON_INODES
PREEMPT_NOTIFIERS, once virtualization configured.

Once virtulization configured, make PREEMPT_NOTIFIERS, ANON_INODES
selected by default.
What is the motivation for this?  Don't things work as is

You know, kvm depends on these two configrations.  If user doesn't
configure KVM when building host kernel, then PREEMPT_NOTIFIERS and
ANON_INODES shouldn't be selected .  In this case, once user wants to
exercise KVM later, he has to replace the host kernel again. To some
high-end servers, it maybe infeasible to replace kernel and get a
restart.  So I want to get them selected once users doesn't disable
virtulization explictly.

But it also means the user will have these features enabled needlessly. Right now when KVM is the only option under the virtualization menu, this may be okay, but if other features are added, this is not acceptable.

Really, if users want KVM, they should enable it in their kernel configuration.
