[Qemu-devel] [PULL 43/62] target-i386: wake up processors that receive an SMI

[Paolo Bonzini]

An SMI should definitely wake up a processor in halted state!
This lets OVMF boot with SMM on multiprocessor systems, although
it halts very soon after that with a "CpuIndex != BspIndex"
assertion failure.
