[PATCH v2 0/3] xen/arm: Add option to optionally disable trapping on unmapped acceses

["Edgar E. Iglesias" <edgar.iglesias@xxxxxxxxx>]

From: "Edgar E. Iglesias" <edgar.iglesias@xxxxxxx>

This follows up on the virtio-pci discussion and adds a per-domain
option to select the behaviour of accesses to unmapped address ranges.
The new option is trap_unmapped_accesses, it's general but for now
only implemented for ARM.

I'm happy with any name, so if you have better ideas please suggest them!

Thanks,
Edgar

ChangeLog:

v1 -> v2:
* Rename trap_unmapped_mmio to trap_unmapped_accesses
* Generalize to allow other archs to later support this option
* Change dom0less DT binding from boolean to integer
* Remove changes to autogenerated go bindings

Edgar E. Iglesias (3):
  xen/arm: Add way to disable traps on accesses to unmapped addresses
  xen/arm: dom0less: Add trap-unmapped-accesses
  tools/arm: Add the trap_unmapped_accesses xl config option
