This patch adds support for the new tsc-deadline feature flag and a new model to the supported model list describing the Intel Sandy Bridge platform. --- Patches adding the SandyBridge cpu type in qemu are on review and not upstream yet. Please don't prioritize this patch. I sent it for review as the chance that nothing will change is greater than I'll have to post another version.
