Subject: linux-next: build failure after merge of the xen-tip tree

Hi all,

After merging the xen-tip tree, today's linux-next build (x86_64
allmodconfig) failed like this:

ERROR: modpost: "acpi_os_ioremap" [drivers/gpu/drm/gma500/gma500_gfx.ko] undefined!

Caused by commit

  de4237fd5174 ("xen: allow mapping ACPI data using a different physical address")

acpi_os_ioremap is not exported to modules.

I have used the xen-tip tree from next-20240910 (as the next-20240911
version had a different build failure).
