Some fixes since last version:

 - Add a patch 19/23 for disabling ACPI for Xen on ARM64 for now to fix
   compile errors on XEN ACPI, Stefano and Julien are ok with this
   temporary solution.
 - Add patch "ARM64 / ACPI: Don't unflatten device tree if acpi=force 
   is passed", which will fix the problem that the device tree will
   be unflattened even if acpi=force passed, that will not obey the
   policy.
 - update patch "irqchip: Add GICv2 specific ACPI boot support",
   which will cause compile error on i386 with both DT and ACPI
   enabled:

   All error/warnings:

                     from drivers/irqchip/irqchip.c:11:

   That's because of I include the <asm/irq.h> in <linux/acpi_irq.h>,
   and <linux/acpi_irq.h> will be put on the top of all head files,
   so use <linux/irq.h> instead of <asm/irq.h> in acpi_irq.h (in
   <linux/irq.h>, it will include <linux/*.h> before include
   <asm/irq.h>), this is the only update for this patch.

Lorenzo will send some cleanup patches on top of this one soon.

Thanks

OK, so I don't think there's anything more I need to ACK in this series, so
it is now up to the maintainers of ARM64 and the other subsystems involved
to decide whether or not to apply it.

If you need to change any patches that I've already ACKed, please let me know,
but otherwise I'm not going to look at this series any more unless specifically
requested.

OK, thank you very much!
