Ping... When may I expect reviews for this?

(1) AIUI,
- Michael hasn't acked this series, but he didn't NAK it either -- the
two of us disagree on his most recent review, but that shouldn't be
reason for others not to look at the series,
- he's alrady cooking a series based on this one.

(2) I'm aware that we're in soft freeze for 1.5 now. I'm just saying I
won't touch the HPET or SRAT until this MADT series is sufficiently
acked. I need to be able to trust the structure if I want it to carry
the HPET and the SRAT too. (I don't insist in the slightest on
(co-)owning this task, ie. there's no time pressure from my side. I'm
just pointing out a dependency.)

Thanks
Laszlo
