For the purpose of the CI testing, let's use the fork [1] from upstream XTF with implemented support for arm64 (the upstream XTF only supports x86). Add a new script under automation/scripts to be used by the CI XTF test jobs to perform the following tasks: - Compiling XTF, - Generating u-boot script using ImageBuilder, - Running Xen with XTF as domU in pure dom0less configuration using Qemu, - Checking test result. The script takes the name of the XTF test to run as a first parameter.

However the operation here really is read-only: we read from the string and write it to the ring, so the C stub should implement the read-only string version, and if needed we could use Bytes.unsafe_to_string to be able to send 'bytes'. However that is not necessary as the 'bytes' version is dropped above.

In fact, this removes one dependency on Xen being "at 0" (the XEN_IMG_OFFSET passed as src) for relocation to occur. This removes all the temporary pagetable handling under the covers of move_memory(), and results in a forward copy rather than a chunked backwards copy (caused by move_memory() always constructing src and dst in a way to trigger memmove() to copy backwards). With the penultimate caller of move_memory() dropped, clean up the API. Drop the keep boolean, folding in 0 from the final caller, and drop the return address which has been unused since c/s 0b76ce20de85 ("x86/setup: don't relocate the VGA hole.") in 2007.

Replace the function by mfn_to_nid() plus a page_to_nid() wrapper macro. Replace call sites by the respectively most suitable one. While there also - introduce a !NUMA stub, eliminating the need for Arm (and potentially other ports) to carry one individually, - drop the (strictly speaking wrong) "pure" attribute from the function, - extend a condition in dump_numa() to make sure that none of the assertions would trigger for empty or (unlikely) single-page nodes (at the same time this also prevents the warning printk() to be issued for every empty [e.g. CPU-only] node).

This was the case with the scenarios described in XSA-156. Make use of the Notify VM Exit mechanism, that will trigger a VM Exit if no interrupt window occurs for a specified amount of time. Note that using the Notify VM Exit avoids having to trap #AC and #DB exceptions, as Xen is guaranteed to get a VM Exit even if the guest puts the CPU in a loop without an interrupt window, as such disable the intercepts if the feature is available and enabled. Setting the notify VM exit window to 0 is safe because there's a threshold added by the hardware in order to have a sane window value. Note the handling of EXIT_REASON_NOTIFY in the nested virtualization case is passed to L0, and hence a nested guest being able to trigger a notify VM exit with an invalid context would be able to crash the L1 hypervisor (by L0 destroying the domain). Since we don't expose VM Notify support to L1 it should already enable the required protections in order to prevent VM Notify from triggering in the first place.

Such detection works by triggering a vmexit, which ought to be enough of a pause to prevent a guest from abusing of the Bus Lock. Add an extra Xen perf counter to track the number of Bus Locks detected. This is done because Bus Locks can also be reported by setting the bit 26 in the exit reason field, so also account for those. Note EXIT_REASON_BUS_LOCK VMExits will always have bit 26 set in exit_reason, and hence the performance counter doesn't need to be increased for EXIT_REASON_BUS_LOCK handling.
