Merge branch 'vm-cleanups' (unmap_vma() interface cleanup)
This series sanitizes the interface to unmap_vma(). The crazy interface
annoyed me no end when I was looking at unmap_single_vma(), which we can
spend quite a lot of time in (especially with loads that have a lot of
small fork/exec's: shell scripts etc).
Moving the nr_accounted calculations to where they belong at least
clarifies things a little. I hope to come back to look at the
performance of this later, but if/when I get back to it I at least don't
have to see the crazy interfaces any more.
* vm-cleanups:
vm: remove 'nr_accounted' calculations from the unmap_vmas() interfaces
vm: simplify unmap_vmas() calling convention
