Many reasons.  Developers like the ability to rmmod and modprobe during 
development.  Distros like to keep their non-modular core small.  There 
is an external module distribution that allows users to graft a new kvm 
on an old kernel, which our testers and bleeding edge users like.  
Because it's there.

There's always CONFIG_KVM=y if you don't want it.

svm can writeback into memory at odd times if we don't do this, and the 
cost is small - clear a bit in EFER.  There's no reason to be lazy.
