When Xen is compiled for x86 on an arm machine, libacpi build is failing
due to a wrong include path:
- arch-x86/xen.h includes xen.h
- xen.h includes arch-arm.h (as __i386__ and __x86_64__ are not defined
but arm ones are).
To solve this issue move XEN_ACPI_ definitions in a new header
guest-acpi.h that can be included cleanly by mk_dsdt.c.
Inside this header, only protect the definitions using ifdef
__XEN_TOOLS__ as the defines are not used anywhere in the hypervisor and
are not expected to be.
Previous users needing any of the XEN_ACPI_ definitions will now need to
include arch-x86/guest-acpi.h instead of arch-x86/xen.h
Fixes: d6ac8e22c7 ("acpi/x86: define ACPI IO registers for PVH guests")

ACPI builder for domain firmware BUILDING ACPI ----------------- Users of ACPI builder are expected to provide an include file that makes available the following: * strncpy * printf * NULL * test_bit * offsetof When compiling build.c, the name of this include file should be given to compiler as -DLIBACPI_STDUTILS=\"<filename>\". See tools/firmware/hvmloader/Makefile for an example. Note on DSDT Table ------------------ DSDT table source code is acpi_dsdt.asl It is already compiled and the output is acpi_dsdt.c Usually, user is not expected to change the acpi_dsdt.asl. In case that the acpi_dsdt.asl need to be updated, please Follow the instruction: # make acpi_dsdt.c
