there's a few weeks of inactivity expected in that area i think - so if
you'd like to pick it up from there, feel free ...

but apic_32/64.c is looking already pretty good in tip/master:

1 file changed, 391 insertions(+), 358 deletions(-)

the most significant bit of that delta seems to be around x2apic,
calibration differences and some older 32-bit legacies which are not on
the 64-bit side (but which we can add safely).
