[POWERPC] unmap_vm_area becomes unmap_kernel_range for the public
This makes unmap_vm_area static and a wrapper around a new exported unmap_kernel_range that takes an explicit range instead of a vm_area struct. This makes it more versatile for code that wants to play with kernel page tables outside of the standard vmalloc area. (One example is some rework of the PowerPC PCI IO space mapping code that depends on that patch and removes some code duplication and horrible abuse of forged struct vm_struct).

The first of these two routines is invoked after map_vm_area()
has installed the page table entries. The second is invoked
- before unmap_vm_area() deletes the page table entries.
+ before unmap_kernel_range() deletes the page table entries.
There exists another whole class of cpu cache issues which currently
require a whole different set of interfaces to handle properly.
