This patch series mainly add MP support to QEMU as well as some other necessary fixes for x86.
Verified by booting Linux kernel on QEMU i440FX and Q35, and make sure I/O APIC interrupt is being used by the kernel with the help of MP table provided by U-Boot.
This series is the prerequisite for the follow-up ACPI support which is currently being worked on by Saket.
