[patch] Renaming kvm_arch in view of upcoming architecture ports

Hi,
in view of the upcoming architecture ports, this is a little cleanup 
patch that renames the current "_arch" to "_x86"
e.g. kvm_arch_ops -> kvm_x86_ops

I discussed with some people about names like kvm_x86_arch_ops or 
kvm_subarch_ops, ... but at the end we thought that "arch" has a special 
meaning in linux and so it should be freed for the real architecture 
ports of kvm that show up slowly on the horizon (look at Tucson).
I want to invite everyone to comment about what may be a more 
appropriate name in order to find out what naming scheme the community 
wants.

I attached the patch to keep the usual form, but actually it is just 
what comes out executing the following:
  perl -p -i -e "s/_arch/_x86/g" drivers/kvm/*

-- 

Grüsse / regards, 
Christian Ehrhardt
