Subject: [PATCH v2 00/13] SMM implementation for KVM

This brings together the remaining parts of SMM.  For now I've left the
"weird" interaction between SMM and NMI blocking, and I'm using the same
format for the state save area (which is also the one used by QEMU) as
the RFC.

It builds on the previous cleanup patches, which (with the exception
of "KVM: x86: pass kvm_mmu_page to gfn_to_rmap") are now in kvm/queue.
The first six patches are more or less the same as the previous version,
while the address spaces part hopefully touches all affected functions
now.

Patches 1-6 implement the SMM API and world switch; patches 7-12
implements the multiple address spaces; patch 13 ties the loose
ends and advertises the capability.

Tested with SeaBIOS and OVMF, where SMM provides the trusted base
for secure boot.

Thanks,

Paolo
