[PATCH] memory hotplug prep: kill local_mapnr

The following series implements memory hot-add for ppc64 and i386.  There are
x86_64 and ia64 implementations that will be submitted shortly as well,
through the normal maintainers.

This patch:

local_mapnr is unused, except for in an alpha header.  Keep the alpha one,
kill the rest.
