[v2] hw/xen: Have most of Xen files become target-agnostic

[PATCH-for-9.0 v2 15/19] hw/xen: Reduce inclusion of 'cpu.h' to target-specific sources

Posted by Philippe Mathieu-Daudé 2 years, 2 months ago

We rarely need to include "cpu.h" in headers. Including it
'taint' headers to be target-specific. Here only the i386/arm
implementations requires "cpu.h", so include it there and
remove from the "hw/xen/xen-hvm-common.h" *common* header.
