I'm going to put all the above except for "Implement AArch64
DAIF system register" (which had a review nit that needs fixing)
into target-arm.next. Patches 2-17 and 22-24 have all been
reviewed; 1, 18, 19 and 20 have had no adverse comment and
are generally fairly straightforward, and they've been on
list for a while now so I think they're ok to go in.

Nobody's reviewed these yet, so I'll hold on to them and
send them out with the next version of this patchset, which
might even have enough patches in it to actually boot a guest.

[I'm not planning to try to get system emulation into
QEMU 2.0; I think it's good to get the bulk of the
underlying foundational work in, though, so that the
remaining patchset is more manageable.]
