A suspended VM can cause spurious soft lockup warnings. To avoid these, the
watchdog now checks if the kernel knows it was stopped by the host and skips
the warning if so.

The KVM_GUEST_PAUSED flag will prevent a guest from compaining about a soft
lockup but it can mask real soft lockups if the flag isn't cleared when it is
no longer relevant. This patch adds a kvm ioctl that the hypervisor will use
when it resumes a guest to start a timer for aging out the flag. T
Now that we have a flag that will tell the guest it was suspended, create an
interface for that communication using a KVM ioctl.
