Add a cpu notifier to virtio-net, so that we can reset the virtqueue affinity if the cpu hotplug happens.

When in SYS_STATE_suspend, and going through the cpu_disable_scheduler path, save a copy of the current cpu affinity, and mark a flag to restore it later. Later, in the resume process, when enabling nonboot cpus restore these affinities. v2: Fix formatting problems. remove early return in cpu_disable_scheduler() path. v3: Fix remaining errant tab Move restore_vcpu_affinity() to thaw_domains(),

Hey Stefano, I setup a cross ARM build system so that the generic changes won''t cause build issues on ARM (and actually caught a bug with fallback.o being enabled there - I''ve a fix for that). But more interestingly the build system I do also makes a variations of config entries. So there is the allmodules, allyes, allyes, but all Xen drivers are modules, etc. I found out that

This patch adds new control messages for vcpu hotplug events. Via the xm vcpu_hotplug sub-program, VCPUS in domains can be enabled/disabled when CONFIG_HOTPLUG_CPU is enabled in the target domain''s kernel. Currently there is nothing that tracks whether a VCPU is up or down. My previous [1]patch added a new per-VCPU flag (VCPUF_down) which could be used to keep track of which VCPUS are
