Hi, While looking at Xen target-specific code, I noticed some generic code used by x86 which is not implemented for ARM. Maybe ARM machines don't need it, I don't know. But I wanted to see if I can get this common code target agnostic and build it once, possibly bringing smth useful to ARM. The changes don't break CI testing and Avocado local tests. If this xen_memory_listener feature isn't required for ARM, I'll send follow up patch that keep this series with common xen_memory_listener but with a runtime flag to disable. Patches do the usual "change target-specific API to a target-agnostic one", in particular using "exec/target_page.h" at runtime. Then non-x86 code is extracted, then merged to the generic xen/xen-hvm-common.c. Thoughts? Regards, Phil.
