Hi Konrad,
After merging the xen-two tree, today's linux-next build (x86_64
allmodconfig) failed like this:
drivers/xen/xen-acpi-memhotplug.c: In function 'acpi_memory_get_device':
drivers/xen/xen-acpi-memhotplug.c:191:2: error: implicit declaration of function 'acpi_bus_add' [-Werror=implicit-function-declaration]

Caused by commit 181232c249f0 ("xen/acpi: ACPI cpu hotplug").
These commits interacted with commits 636458de36f1 ("ACPI: Remove the
arguments of acpi_bus_add() that are not used"), 0cd6ac52b333 ("ACPI:
Make acpi_bus_scan() and acpi_bus_add() take only one argument") and
b8bd759acd05 ("ACPI / scan: Drop acpi_bus_add() and use acpi_bus_scan()
instead") from the pm tree.
I have added this merge fix patch and can carry it as necessary (I did
*not* fix the warnings above):
