New Revision: 309522
URL: https://svnweb.freebsd.org/changeset/base/309522

Log:
  Fix a typo (move parenthesis to correct location in the line).
  
  Before this, it would cause the one consumer of this API in powerpc usage
  (dev/dpaa) to set the PTE WIMG flags to empty instead of --M-, making the
  cache-enabled buffer portals non-coherent.
