[PATCH v2 0/4] OvmfPkg: broadcast SMIs and dynamically revert to traditional AP sync mode

[Laszlo Ersek <lersek@redhat.com>]

This is version 2 of the series originally posted here:
<https://lists.01.org/pipermail/edk2-devel/2016-November/004702.html>.

In this version, OVMF negotiates the broadcast SMI feature with QEMU
dynamically, using the interface added in this QEMU series:
<http://lists.nongnu.org/archive/html/qemu-devel/2016-11/msg03582.html>.
If the feature is available, OVMF selects it, and also re-sets the
UefiCpuPkg PCDs that are related to BSP-AP synchronization to their
"UefiCpuPkg.dec" defaults.
