  SVN rev 188350 on 2009-02-08 22:54:58Z by imp
  
  When bouncing pages, allow a new option to preserve the intra-page
  offset.  This is needed for the ehci hardware buffer rings that assume
  this behavior.
  
  This is an interim solution, and a more general one is being worked
  on.  This solution doesn't break anything that doesn't ask for it
  directly.  The mbuf and uio variants with this flag likely don't work
  and haven't been tested.
  
  Universe builds with these changes.  I don't have a huge-memory
  machine to test these changes with, but will be happy to work with
  folks that do and hps if this changes turns out not to be sufficient.
