Philippe Mathieu-Daudé May 7, 2020, 3:58 p.m. UTC
This code is not related to hardware emulation.
Move it under accel/ with the other hypervisors.

Signed-off-by: Philippe Mathieu-Daudé <philmd@redhat.com>

We could also move the memory management functions from
hw/i386/xen/xen-hvm.c but it is not trivial.

Necessary step to remove "exec/ram_addr.h" in the next series.

Hi,

This series failed the docker-quick@centos7 build test. Please find the testing commands and

locally.

I'll resend adding the following patch checking for xen_enabled() before 
calling, as we do with other accelerators:
