This patch series combines the global include files into a single include
and cleans up dependencies that were in the wrong location. We had code
dependencies on the UNISYSSPAR Kconfig flag instead of the VISORBUS config
flag. UNISYSSPAR is just there for organizational purposes.

The Kconfig flag UNISYSSPAR depended on ACPI and X86, these dependencies
really belong to visorbus, so move them there.

Let's document the magic a bit, especially why device_hotplug_lock is
required when adding/removing memory and how it all play together with
requests to online/offline memory from user space.

Let's perform all checking + offlining + removing under
device_hotplug_lock, so nobody can mess with these devices via
sysfs concurrently.

Maybe there ought to be a define so you can do:
DEFINE_BITMAP(value_bitmap, 32);
While it might just generate an unsigned long [] there is probably

You need to sort out whether the byteswap is needed or not.
