Xen-unstable :can't boot HVM guests, bisected to commit: "hvmloader: indicate ACPI tables with "ACPI data" type in e820"

[Sander Eikelenboom <linux@xxxxxxxxxxxxxx>]

Hi Igor/Jan,

I tried to update my AMD machine to current xen-unstable, but
unfortunately the HVM guests don't boot after that. The guest keeps
using CPU-cycles but I don't get to a command prompt (or any output at
all). PVH guests run fine.

Bisection leads to commit:

8efa46516c5f4cf185c8df179812c185d3c27eb6
hvmloader: indicate ACPI tables with "ACPI data" type in e820

I tried xen-unstable with this commit reverted and with that everything
works fine.

I attached the xl-dmesg output.
