[Qemu-devel] [qemu PATCH 0/5] publish etc/acpi/APIC in fw_cfg

[Laszlo Ersek <lersek@redhat.com>]

This series exports the MADT (APIC) ACPI table under the new
"etc/acpi/APIC" fw_cfg file. I sought to follow the requirements set
forth in [1], the new table is only visible in the patched/patched case.
I cross-tested { master, patched } qemu with { master, patched } seabios
(the APIC, DSDT and RSDT tables) using guest acpidump and dmesg.

The -acpitable command line option is purposely ignored based on the
last paragraph of [2]; the user isn't supposed to pass APIC with that
option.

checkpatch.pl complains a little but (as last time) it's a false alarm.

The series is bisectable.
