New Revision: 338336
URL: https://svnweb.freebsd.org/changeset/base/338336

Log:
  Use the correct register when storing the arm VFP state.
  
  Previously we have been lucky where the state was already in r0, however
  this is not guaranteed. Use the passed in register as the location to
  store the upper half of the arm VFP registers rather than relying on it
  being r0.
