preparations for 4.13.2 and 4.12.4

[Jan Beulich <jbeulich@xxxxxxxx>]

All,

the releases are about due, but will of course want to wait for the
XSA fixes going public on the 22nd. Please point out backports
you find missing from the respective staging branches, but which
you consider relevant. (Ian, Julien, Stefano: I notice there once
again haven't been any tools or Arm side backports at all so far
since the most recent stable releases from these branches. But
maybe there simply aren't any.)

One that I have queued already, but which first need to at least
pass the push gate to master, are

8efa46516c5f hvmloader: indicate ACPI tables with "ACPI data" type in e820
e5a1b6f0d207 x86/mm: do not mark IO regions as Xen heap
b4e41b1750d5 b4e41b1750d5 [4.14 only]

On the Arm side I'd also like to ask for

5d45ecabe3c0 xen/arm64: force gcc 10+ to always inline generic atomics helpers
