Cleanup special cases of paravirt patching: - Xen doesn't need a custom patching function, it can use paravirt_patch_default() - Remove lguest completely from the tree. A LKML mail asking for any users 3 months ago did not reveal any need for keeping lguest [1]. - Remove vsmp paravirt support. This is more kind of a RFC. The code suggests paravirt support in vsmp might be optional and there is no documentation (at least I found none) to support its need. In case the patches make it to the tree there is quite some potential for further simplification of paravirt stuff. Especially most of the pv operations can be put under the CONFIG_XEN_PV umbrella.
