This patchset moves svm towards a lightweight vmload/vmsave path. It was
hindered by CVE-2010-3698 which was discovered during its development, and
by the lack of per-cpu IDT in Linux, which makes it more or less useless.
However, even so it's a slight improvement, and merging it will reduce the
work needed when we do have per-cpu IDT.

KVM: SVM: Move svm->host_gs_base into a separate structure
KVM: SVM: Move fs/gs/ldt save/restore to heavyweight exit path
KVM: SVM: Fold save_host_msrs() and load_host_msrs() into their
callers
