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.
