Notes:
v7:
- no functional changes, pick up Igor's R-b
- rebase to master, resolve conflict with commit abc62c89f319 ("pc.h:
move x-mach-use-reliable-get-clock compat entry to PC_COMPAT_2_8",
2017-01-18)
v6:
- rename "smi_broadcast" to "x-smi-broadcast" [Eduardo]
- pick up Eduardo's R-b
- pick up Michael's R-b
v5:
- replace the v4 patch "hw/i386/pc_q35: advertise broadcast SMI if VCPU
hotplug is turned off" with a simple device property and compat
setting [Igor]
