Dependent on the already existing CONFIG_KVM_GUEST config option
this patch
changes wrteei to wrtee allowing the hypervisor to rewrite those
to nontrapping
instructions. Maybe we should split the kvm guest otpimizations in
two parts
one for the overhead free optimizations and on for the rest that
might add
some complexity for non virtualized execution (like this one).

So this commit message doesnt explain why 'wrtee' facilities doing
whatever optimization and 'wrteei' doesnt.
yep I only explained it elsewhere.
I'll add it here too in the next version - thanks Kumar
(and fix the word otpimizations)
Where is the other discussion? I'd like to understand what's going on
here.. (especially since I added the wrtee[i] changes to kernel way
back when).
