src/sys/arch/x86/x86: mpbios.c
Log Message:
Firecracker and qemu/microvm in MMIO mode don't have ACPI, either
they rely on MP tables, but using it IOAPIC was not detected.
This patch fixes it by adding a Linux-specific behavior, counting
the right amount of entries and then find the IOAPIC entry.
These bugs were found by Colin Percival and described here
https://www.usenix.org/publications/loginonline/freebsd-firecracker
/!\ This needs a new kernel option: MPTABLE_LINUX_BUG_COMPAT
