Intercept guest reads of MSR_IA32_MCG_CAP and limit the number of memory banks reported to one. This prevents us from trying to read status of non-existent banks when migrated to a machine with fewer banks.

Direct calls perform better, so we should prefer them and use indirect ones only when there indeed is a need for indirection.

This patch series implements SMP boot for arch/arm, as far as getting all CPUs up and running the idle loop. Changes from v1: - moved barriers out of loop in udelay() - dropped broken GIC change in favour of explanatory comment - made the increment of ready_cpus atomic (I couldn''t move the increment to before signalling the next CPU because the PT switch has to happen between

libvirt-ocaml is used only by virt-v2v, so move it to this repository, instead of having it around in the common submodule. The removal from common will happen later.

Hi, this is a mostly done attempt to switch to ocaml-libvirt, embedding the latest version of it from git. This way, it is possible to improve the way v2v connects to libvirt for both input, and output modules, and interacts with libvirt (e.g. no more virsh calls needed in virt-v2v). As side effect, virt-v2v now requires libvirt, as keeping it optional would create too much burden. I could not
